Sporlan Controls 900004 1/2 Inch # Regulator Valve W/Strn 0/50#

The Sporlan Controls 900004 is a 1/2-inch pressure regulator valve with a built-in strainer that is commonly used in refrigeration and air conditioning systems. It serves as a control point, controlling the flow of liquid or refrigerant gas to maintain steady and secure pressure levels within the system. An internal mechanism of the valve reacts to variations in the downstream pressure, or the pressure on the valve's outlet side. More liquid or gas can pass through the valve to refill the pressure when the downstream pressure drops below the intended setpoint. On the other hand, the valve partially closes to restrict flow and stop excessive pressure buildup if the pressure rises above the setpoint.
