MPC series Multi-stage pressure control valve utilizes multi-cage to reduce the pressure. It has features of S-shape passageway and high Cv. The valve plug is designed as balancing structure, so it can adjust the flow stable and has excellent anti-differential pressure capability. According to different differential pressure, it can be designed with 1 to 3 stage cage to avoid the generation of flashing and cavitation effectively, ideal for services of high gas or liquid differential pressure, flashing and cavitation.
Design Feature
– Strong flow capacity
– Large guiding area for stable movement
– Wide adjustable range and high adjusting precise
– Ideal for service with high differential pressure
– Low sealing resistance with excellent sealing
– Multi-stage cage design avoiding cavitation and flashing appearance
– Modularized integral structure design for easy inter-changeable
– Ideal for controlling flow of various pressure and temperature
Principle of Operation
The process medium flows through the valve in the direction indicated by the arrow on the body. The position of the 3-stage or 5-stage valve plug determines the free area between the valve seats and plugs and hence the pressure drop or flow rate through the valve. The pressure drop occurs in stages so that critical operating conditions like cavitation, excessive wear and high noise emissions are avoided. Additionally, the plug stem is bottom-guided for added stability and to limit vibrations. A pressure-balanced version can be used with high differential pressures where the force produced by the actuator in the unbalanced version would be insufficient to close the valve. The valves can also be equipped with flow dividers to further reduce the noise level.
