Dual Plate Check Valve Manufacturer

 

Dual Plate Check Valves

The Dual Disc® Check Valve with its compact wafer design and low cost have made it a popular choice when space and price are major factors in valve selection. The compact design features non-slam spring-assisted closing.

Features

  • Versatile design 80% to 90% less than Conventional full-body swing Check valves
  • Dual Discs open to 85 degrees
  • Spring-loaded discs calculated To increase the responsiveness Of the discs
  • Extended long-leg spring

General Application

  • General service piping systems
  • Water, oil, gasoline, chemicals
  •  Gas (compressible gases)
  •  Air (compressed air and blower

Installation

Champion wafer check valves are designed for installation in flanged piping systems, between two flanges. Valves may be installed in vertical or horizontal piping.

Care must be taken to always install the valves with the shafts in a vertical position when installing in a horizontal pipeline. Vertical up flow is always a good installation. Consult factory for vertical down flow. Champion wafer check valves are designed to provide long service life if the velocity is kept within the flow rate shown in the table on page 7 and if a minimum of 5 pipe diameters of straight pipe in front of the valve is maintained downstream from a likely cause of turbulence (i.e., pump discharge, reducers or elbows).

Industry Standards

  • ASME B16.1, B16.5, B16.34, B16.47 and
  • API 594 and 598 • MSS-SP-25, MSS-SP-55
  • API 6A and 6D (as applicable) MSS-SP-61 (standard for the resilient seated, metal seated when required)
