Parker provides the industry's widest selection of check and isolation valves, available in a variety of end connections for use in a range of applications, from air and fuel systems to load holding. Our check and isolation valves utilize a variety of media including oil, air and water, and are made from materials such as aluminum, stainless steel, brass and carbon steel. Parker valves are built to the highest quality standards, recognized around the world for their performance, durability and reliability.
Parker’s Liquid Drain Ball Valve has a spring return handle, and available in either stainless or carbon steel.
Parker’s V2 and V3, rugged, all steel bodied, tiny hand valves are designed to seat tight and permit isolation of small system components. They are primarily used as gauge (V2) and drain (V3) valves.
The Type CK1 Check Valves prevent backward flow of fluid in refrigerant suction, hot gas or liquid lines.
The CK-3 check valve prevents backward flow of high pressure refrigerant gases and liquid.
The Type CK4A Check Valves prevent backward flow of fluid in refrigerant suction, hot gas or liquid lines.
These CK-2 Gas Powered Suction Stop Valves are used on low temperature applications to positively close suction lines and both liquid legs and gas returns on flooded evaporators.
The CK-2D valves are employed as a low pressure drop, gas-powered suction stop valve for low temperature evaporators. These valves are used for suction stop and evaporator equalization following a defrost cycle.
The CK-5 gas-powered suction stop valve provides the normal operating features of the R/S CK-2 suction stop valve and features a built-in failsafe to close the valve until pressure is equalized in the event of a power loss.
The CK-6D is a suction stop valve for hot gas defrost applications. This normally open valve features dual solenoids for equalization and a pressure regulator to prevent the valve from opening during defrost in the event of a power loss.
The S9A and S9W valves are designed to promptly and fully open or close under conditions which make conventional solenoid valves unreliable or unsuitable. The S9 requires no minimum pressure drop to open which makes it ideal for certain applications.
