Pressure reducing control valve
🌐 Product Overview – Multi-Stage Pressure Reducing Control Valve
pressure reducing control valve utilizes a multi-stage sleeve design for pressure reduction. The valve body features an S-shaped flow path design, which minimizes fluid resistance and enhances flow capacity. The valve plug adopts a balanced structure, ensuring smooth regulation and strong resistance to pressure differential.
Depending on the pressure differential across the valve, the valve employs 1 to 3 stages of sleeve pressure reduction, effectively preventing flashing and cavitation.

Pressure Class: ASME CLASS 600 ~ 2500 (PN63 ~ PN420)
Body Materials:
Carbon Steel
Stainless Steel
Alloy Steel
Duplex Stainless Steel
Operation Methods:
PDL Pneumatic Diaphragm Actuator
PCL Pneumatic Piston Actuator
