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.

🔩 Specifications

• Size Range: 1-1/2" ~ 12" (DN40 ~ DN300)

• Pressure Class: ASME CLASS 600 ~ 2500 (PN63 ~ PN420)

• Body Materials:

  • Carbon Steel

  • Stainless Steel

  • Alloy Steel

  • Duplex Stainless Steel

• Operation Methods:
