Introduction

Have you ever wondered how and why valves are made,  processed and then delivered to your door? Well, that’s what I’m here to tell you. Valves are important items used in our everyday life. Without it we wouldn't have things such as heat or water. Valves are used in the basic mechanical functions in our life. It’s essential for all manufacturing processes and every energy production and supply system. There are various steps to make the right valve function for your needs. The basic steps for it to be functionally ready are the design, plastic moulding, mechanical processing, assembly and testing, and quality. The process for it to be manufactured is a complex and long process. It needs to be manufactured for perfect efficiency, and undergo various tests so it's in perfect functioning order befitting our customers.

Checklist

The manufacturing department will find the necessary materials needed to cast the valve best suited for your needs, such as the materials needed to build the valve and the type of material to design the casting of the valve. Will also look for the raw materials needed to build the valve such as the stem, spool, body, disc, and bonnet, making sure that the materials are compliant.  After getting all the materials the team will go over the checklist to make sure everything is done and complete, and to have the final draft of the design completed. Once the design is completed and finalized, it’s time to manufacture them. There are 2 common methods that are used to manufacture the valves, the cast method and forged method.

Cast methods

The cast method body is when the pre-shape is cleaned, the body is put on the turning machine, so the single cutter can cut the desired shape needed. Then a coating material is added over the entire body.  Then the next step is to polish the whole body, create the threads over the body, so attachments can be installed to the body. Each hole would be a different size depending on the valve size requirement. Then it’s painted and baked with elastomer. For the seat, it goes through the same process as the body.  It needs to be aligned perfectly to the body. The stem does not need a lot of manufacturing, it just needs to be cut into the right dimensions.

Forged Method

After choosing the material, it  is cut into a specific length and width. Then it’s forged, each body is heated to a certain degree then the excess material is trimmed from the body. While it’s still hot, it’s molded into the correct shape and then sandblasted, which makes the valve smooth and clean. Machining enhances the size and thread and shapes depending on the design of the valve.

Assembly

After all the materials are ready, then it is time to put them all together. The technicians attach all the components together by hand. 

Testing

Then when everything is ready it undergoes the testing stage to make sure it works and there is no leakage when the fluid goes through. It could range from a couple hours to a day, depending on the valve size. If there is leakage, it’s repaired so it works correctly, otherwise the valve shall move onto the next step, to see if it can handle water pressure. If it can withstand the high pressure, then it passes the test and is ready for the last phase.

Inspection and quality control

After the product passes all the tests, the QA inspector checks the valves for leaks and to make sure there are no production errors. This last inspection is to make sure the quality of the product meets the company’s standards. The product is now ready for consumers to purchase and use.

Anix Valve USA is a valve manufacturer based in Texas, United States. Find out about our wide selection of camlocks at https://anixusa.com/camlock-ss316

What is a camlock?

A camlock fitting, also called a cam and groove coupling, is used to connect two hoses and/or pipes together in a variety of industries, so that goods from one can be transferred to the other. They are extremely useful due to their simplicity and reliability, with the ease of connecting and disconnecting without tools. They are used in homebrew, agricultural, military, and industrial environments but are used mostly in industrial environments, since the hoses tend to be larger in diameters and the cam lock being a heavy duty.

Camlock Materials

The camlocks are great for transferring dry and flowing materials. There are various materials of camlocks that are used for different purposes, stainless steel, polypropylene, and nylon, brass, and aluminum alloy. depending on the industry. The materials used are dependent on the type of elements that will be going through the camlock. A stainless steel camlock is used for acid, alkali, and corrosive substances. Polypropylene and nylon camlocks are used in the chemical industry, for transmitting liquid, and for irrigation in the agricultural industry. A brass camlock is mostly used for acid and alkali substances, but can be used for transmitting saltwater. Aluminum alloy camlocks are good for freshwater and/or for mixing oil and water together. When using camlocks they should not be used for steam applications. If it was used in a steam situation it would be very dangerous and could result in an explosion. 

Camlock Styles

There are various styles as there are materials.The type of styles that they have are male adapter with a female thread,  female coupler with a male thread, coupler with a shank (hose barb), coupler with a female thread, adapter with a shank, adapter with a male thread, dust cap, and dust plug. It's important to know what each style is so you know which type is right for the job. 

Benefits of camlock fittings

There are many benefits to using camlocks, besides the cost effectiveness. One benefit is durability, since they come in various materials it's easy to choose the correct one for your situation. Another is that it is quick to set up and use. They are designed to be easy to connect to pipes or hoses.  It’s designed so there’s no need for more attachments except the camlock.  Just simply lock in the camlock in place and it's ready to use. It's versatile which means it can be used in any application. They are also reliable-by choosing the correct size, material, and pressure rating, for any application.

There are various types of camlocks such as a snaplock camlock, saflok camlock, and an eco camlock  A snaplock is used for carrying liquids, powders, and granules but shouldn't be used for compressed air. It’s usually used in agricultural or manufacturing industries due to the safe, clean transfer of various fluids. These are good for coupling systems of low and medium pressures and for connecting hose lines quickly and swiftly. A saflok camlock is an automatic camlock. It has locking arms which is designed to prevent any spillage. The automatic lock system is built into the camlock arms. It's just like a standard camlock, except it can't be easily opened by accident. An eco camlock is more cost effective and lightweight. It’s used for light duties, limited to certain applications that have less mechanical stress.

Anix Valve USA is a valve manufacturer based in Houston, Texas. Find out about our wide selection of butterfly valves at https://anixusa.com/butterfly-valves-2

What is a butterfly valve?

A butterfly quarter is a quarter-turn valve, allowing for a quick shut off making it cost efficient. The “butterfly” is a metal disc positioned in the center of the pipe with a rod passing through the disc to an actuator on the outside of the valve. It is in the shape of a gear, that is usually referred to as a gearbox, while the handwheel is connected to the stem. Rotating the actuator turns the disc either parallel or perpendicular to the flow.  The valve is fully opened or closed when the disc is rotated a quarter turn, to stop, regulate, or start the flow. They are suited for handling large flows of liquid and gas at low pressures.

Types of Butterfly Valves

The most common body types of the butterfly valves manufactured are short, circular body, a round disc, metal-to-metal or soft seats, top and bottom shaft bearings, and a stuffing box. Each design for the valve varies depending on the use.  One type is the wafer type that fits in between 2 flanges. Another type is the lug wafer type, where it's held between 2 flanges by bolts, and that pass through the valve casing. They are an advantage to the gate, globe, plug, and ball valves, since the maintenance cost to fix is low and there are a lot of moving parts which allow any fluid to flow freely.

Advantages of Butterfly Valves

It's used for different fluid services and is best in slurry situations. One advantage is that it is compressed so it doesn't need a lot of space , compared to the other valves. It's not heavy, it's lightweight. It's quick to use the handle and it does not require a lot of time to open or close. It is audible in different sizes, from small to very large. It also has a low pressure drop but a high pressure recovery.

Actuation method

Butterfly valves come in various operated handles, such as manually by handles and gears or automatically by electric, pneumatic or hydraulic actuators. Manual actuations are easy to operate and inexpensive, and are made as either a hand lever or a gear. The handlebar is the most common of butterfly valves and is capable of being open, partially closed, and fully closed. The gears are designed for much bigger valves, in which it increases the torque but decreases the speed for the opening and closing of the valve. These are self locking, and have position indicators. Automatic actuations are the most reliable since you can use it in any remote location. It is designed to fail open(it stays open if actuator fails) and or fail closed ( it stays open if actuator fails). One type is electric which uses an electric motor at the stem. Another is pneumatic which compresses the air so it can open and or close. And lastly, there is the hydraulic which uses a hydraulic pressure to move a piston or diaphragm to open/close the valve.

Butterfly valve vs ball valve

Butterfly valves are cheaper, easier to install, and is a small installation footprint compared to ball valves. Butterfly valves don’t have a complicated design so they don't have a lot of moving parts which means it is easier to repair and cheaper to produce. But, butterfly valve discs can not be cleaned due to their position and location. Ball valves are more suited for high pressure small applications, since they don't cause a lot of pressure to the system.
