Flow control valve is used to control the flow of gas and liquid. These valves have a number of internal components that determine how they function. They can either allow the flow of fluid through the valve or restrict the flow. They operate by exerting pressure on the valve’s seat and disk to allow or restrict fluid flow.
Needle valves restrict or allow the flow of liquid:
Needle valves restrict or allow the flow of liquid by altering the orifice size. These valves are often manually operated, but some are designed as variable restrictors. Variable restrictors are constructed without a handwheel and adjust to a specific rate of flow, allowing for flexible operation within a variety of systems.
Butterfly valves restrict or allow the flow of gas:
Butterfly valves restrict or allow the flow of a gas or liquid by closing or opening a valve in a closed position. Their lightweight and compact construction make them a convenient and economical alternative to ball and gate valves. They also require less maintenance. They can be operated at various temperatures and handle gas and liquids containing suspended solids. However, they are not ideal for higher-pressure differentials.
Pinch valves provide 100% tight shut-offs:
Pinch valves are used in a wide range of applications. These valves offer high shut-off pressure and a seal that is 100% tight. As a result, they are a great choice for fluids containing solid particles and contaminants. In addition, their design allows them to be installed in both directions, and their structure is streamlined to enable easy sleeve replacement, maintenance, and operation.
Motorized flow control valves:
Motorized flow control valves are designed to control the flow of liquids. They open and close the valve based on changes in pressure or temperature. Often, these valves need to be used in areas where flow is critical to the operation. Fortunately, there are many different types of motorized flow control valves. In order to find the right one for your specific needs, it’s important to consider the specifics of your operations.
Check valves
Check valves are a common device for flow control in industrial settings. Their unique design prevents backflow, providing one-way flow. They can be as small as DN3 (NPS 1/8 in) in size. These valves are constructed with two-level valve seats and built-in channels. These valves are used in various industries that need to control air, gas, or liquid flow.
Plug valves
Plug valves are used to control fluid flow in industrial processes. They are generally L-shaped with a handle attached to the larger end. Their other end is open to the outside. A quarter-turn mechanism can be used to retain the plug.
