G1PR / H1PR Pressure Reducing Valve

The Clorius G1PR / H1PR pressure reducing valves are a self-acting unit consisting of a valve, springs, an actuator and one capillary tube connected on the upper side of the actuator. The G1PR / H1PR pressure reducing valves are designed for maintaining the pressure downstream of the valve to an adjusted setpoint value.

The Clorius G1PR / H1PR pressure reducing valves are a self-acting unit consisting of a valve, springs, an actuator and one capillary tube connected on the upper side of the actuator. The G1PR / H1PR pressure reducing valves are designed for maintaining the pressure downstream of the valve to an adjusted setpoint value.

Function

The medium flows through the free area between the seat and cone in the direction indicated by the arrow on the body. The position of the valve cone determines the flow rate and consequently the pressure ratio across the valve. The downstream pressure is transmitted through the compensation chamber, and the capillary to the diaphragm converted into a positioning force. This positioning force is adjusting the cone with dependence on the force of the operating springs.

The spring force can be adjusted by using the setpoint adjuster. The valve cone is pressure balanced. The pressure acts onto the bottom and top surface of the cone at the same time. In this way, the forces produced by the media are compensated.

Design

The pressure reducing valve is a self-acting unit consisting of a valve, springs, an actuator and one capillary tube connected on the upper side of the actuator. The valve body is made of nodular cast iron or cast steel. The seat and cone are made of stainless steel. The diaphragm is made of EPDM or NBR rubber, depending on the medium to be controlled.
