The plate valve has 2 primary components within it – i.e., the valve disk and dampening disk. Radiused disk compressor valves are also designed in such a way that they perfectly align with the valve seats. The ones above may be the major compressor valve types, but there are other types of valves in and around reciprocating compressors or found at a natural gas compressor station.
Cook Compression is an innovator in the design, manufacture and application of compressor valves. From precision-crafted metal plate valves to the latest high-performance designs with non-metallic internals, we offer solutions for any reciprocating compressor in any type of service. Cook Compression manufactures complete valve assemblies, as well as plates, discs, rings, buttons, poppets, damper plates, spring plates, leaf springs and other metallic and non-metallic components for any make or model valve.
air compressor valve types Related Question:
Which type of valves are used in compressor?
Explanation: Plate type or Reed type valves are used in reciprocating compressors. These valves are either floating or clamped, usually, backstops are provided to limit the valve displacement.
What type of valves are most commonly used in an air compressor?
Solenoid valves and ball valves are often used in compressed air systems. They are for example used to control actuators or the main air supply. To prevent leakage and pressure drops during the night, a solenoid valve or ball valve can be installed at the compressor output.
What are the two valves on an air compressor?
On reciprocating piston compressors First, there are 2 check valves, or sets of check valves used inside the piston head to control the airflow from and to the cylinder. The air is sucked in through the inlet (check-) valve when the piston moves down.
How do the valves work on an air compressor?
In the case of your compressor, the check valve controls the flow of air between the pump and the tank. The valve is self-regulated, which means that it relies on the directional flow of air to open and close. Air should only travel from the tank to the pump, not the other way around.
How do reed valves work air compressor?
Compressor reed valves are thin steel flaps fastened to the valve plate. Reed valves allow refrigerant into and out of each cylinder as the piston travels up and down the cylinder wall.
What is concentric valve?
Concentric valves are a space-saving alternative to conventional inlet/outlet valves. They are suitable for all types of compressors in the lower power range. In concentric valves, the suction and discharge parts are integrated in a common valve body. This allows a very compact design of the compressor.
What is a poppet type valve?
A poppet valve consists of an orifice that is opened and closed by raising and lowering a sealing surface onto the orifice. It usually has an internal spring that holds the valve in the closed position. When the spring force is overcome, the sealing surface lifts off the orifice and the valve opens.
What type of valve is a butterfly valve?
The butterfly valve is classified as a quarter-turn valve. It works like a ball valve for quick shutoff, but unlike a ball valve, the butterfly valve can also open and close incrementally. This difference means that the disc is always present in the flow and allows for a drop in pressure.
How can you tell the difference between an air compressor and a suction valve?
The suction valves permit flow into the cylinder but not back out, and discharge valves permit flow to exit the cylinder but not return back in. Suction and discharge valve failures are the most common component failure in a reciprocating compressor.
What is IGV valve?
Inlet Guide Vane (IGV) This is another common type of inlet valve, but its design is distinctly different from that of a butterfly valve. An IGV regulates airflow using a series of radial blades or “guide vanes” arranged in the intake. When the valve is open, the vanes are parallel to the airflow.
What is IGV in compressor?
Variable inlet guide vane (IGV) is used to control the mass flow and generate prewhirl in centrifugal compressors. The efficient operation of IGV is limited to the range of aerodynamic characteristics of their vane profiles.
Where is the unloader valve on an air compressor?
Where Is the Unloader Valve Located? If you own a smaller reciprocating air compressor, you’ll likely find the unloader valve mounted on or inside the pressure switch. When the switch shuts the compressor off, it actuates the valve.
Why do air compressors have plate type valves?
Plate valves are designed to withstand high pressure and dirty gas applications. There are two main components in the plate valve: the valve disc and dampening disc. Because plate valves are used in dirty gas applications, the valve disc must be resistant to any particles contained in these gases.
What are gate valves made of?
Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels.
What are the two main types of compressor?
The two main types of compressors are dynamic and positive displacement. The positive displacement compressor is probably the one you’re familiar with. It traps gas in a volume and then decreases that volume. The decrease in volume causes a rise in pressure.
