The Common Types of Valves

The accessory that has control over the flow and adjustment of any fluid is accepted as valve. The action of re-direction and controlling fluid is done by closing, aperture or partially opening/closing the passageway. Most of the valves action this way, about there are few others that action differently, like the thermostatic re-circulating valve. Following are some of the frequently acclimated valves in today’s industry.
As the name suggests, they have only two functions, to open and close the flow of the fluid. Though it may seem like an easy task, the designs are quite complicated. This is why you have to depend on models like FC gate valves for long lasting and quality products. The list of such valves is comprised below.
Choke Valve: Check Valve are generally used in drip irrigation emitters and irrigation sprinklers. Composition disc valves are ideal for applications involving gritty liquids. A clapper valve is a type of check valve which is used in fire fighting. This type of valve is used where high pressure is required, like that in oil wellheads. The function of a choke valve is to control the flow of fluid; the flow depends on how wide the valve is opened. In oil industries, choke valves are generally made of tungsten carbide or inconel.
Gate Valve: Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. The gate is usually wedge shaped. Gate valve is used in almost every industry. As the name suggests, gate valve is closed either by a gate or a rectangular wedge. This type of valve is useful only where flow in a straight line is expected. For throttling purposes this gate valve is not the type. FC gate valve is the most common model of gate valves used now a days. Like for example, renowned manufacturers like Integrated Equipment design FC style gate valves that are made with forged body and slab-gate.
Diaphragm Valve: Diaphragm valves are related to pinch valves, but use an elastomeric diaphragm, instead of an elastomeric liner in the valve body, to separate the flow stream from the closure element. Diaphragm valves, also known as membrane valves are made up of a diaphragm, ports and saddle. Diaphragm valve is used in bio-pharmaceutical companies, for the corrosive and dirty service purposes.
Pinch valve: A pinch valve is a full bore or fully ported type of control valve which uses a pinching effect to obstruct fluid flow. There are a few types of pinch valves based upon application. Pinch valves used for fluids usually employ a device that directly contacts process tubing.
The above mentioned were some of the most common types of valves, there are many more. Whichever type of valve you use or modify, make sure to buy it from reliable manufacturers like Integrated Equipment which designs all components of Wellhead equipment ranging from FC gate valves to tubing heads and spools.Datian Valve
