RST PN16/150LB SS316 SS304 WCB Dual Plate Wafer Check Valve
- RST Valve company is a industry valves manufacturer, including Thread & Flange Ball Valves, Gate Valves, Globe Valves, Check Valves, Y Strainers in stainless steel, carbon steel, cast steel, forged steel and alloy steel.
- Check Valves mainly has Thread ends Swing Check Valve, Stainless Steel Vertical type Check Valve, Screwed ends CF8M 200PSI Y type Check Valve, Stainless Steel Wafer type Check Valve, Single Disc Wafer type Check Valve, Single plate Lift type Wafer Check Valve, Dual Plate Wafer Type Check Valve, Cast Steel Flange ends Swing Check Valve, Stainless Steel Flange ends Lift type Check Valve, API Flange ends 150LB Swing Check Valve, DIN Standard Lift type Flange Check Valve.
- Dual plate, or double-door, check valves consist of two plates hinged in the center and spring loaded to assist in closing. They can be used for most media and possess good flow capacity. Sizes range from 2 inches to 60 inches and larger. Because of their design, dual plate check valves are lightweight and have compact face-to-face dimensions. As with butterfly valves, the compact design of dual plate types can require less support and shrink the needed size for a mechanical room. Dual plate valves are available in various body styles that include wafer, lug, and flange; some meet the popular API 594 face-to-face dimensions. Dual plate valves require removal from the line to perform inspection or repair.
Applicable Standards:
- Design and Manufacture API6D, API 594
- Face to face: API 594, API 6D , DIN 3202
- VALVES: ASME B16.34
- END FLANGES: ASME B16.5
- INSPECTION AND TEST: API 598
Design Description:
- PRESSURE: 150# 300# 600# 900# 1500# 2500#
- Wafer check valve is applicable for various pipelines with norminal pressure of PN1.0MPa-42.0MPa, Class150-2500 and nominal diameter
of DN15-DN1200, NPS 1/2"-48" and working temperature of -196ºC up to +540 ºC to be used for pretecting from medium backflowing.
The different materials selection can apply to the medium involving water, oil, nitric acid,, acetic acid, strong oxidizing medium and urea , etc.

Features:
- ROBUST DESIGN
This is a self acting, non=return, single plate, wafer type swing check valve which provides high quality and reliability within a simplified construction. Available in both carbon steel and stainless steel.
- MINIMAL HEAD LOSS
The low inertia disc is designed to open and close under low differential pressure conditions. Also, the short pattern design and straight flow path minimize pressure drop across the valve.
- ECONOMICAL DESIGH
The low weight and short face to face dimensions provide an economical, space-saving solution. Additionally, flange gaskets are typically not required due to the built-in, body seal O-rings.
- RESILIENT SOFT SEATS
Soft seats ( PTFE or BUNA) combined with a gravity assisted disc help to ensure a positive shutoff which creates a bubble tight seal that meets or exceeds API 598 leakage requirements.
- VERSATILE DESIGN
This valve can be installed between weld neck or slip-on type companion flanges of different standards. This valve can not be installed in a vertical pipeline with downward flow.
- FUGITIVE EMISSION DESIGN
The one piece body design eliminates potential leak paths to the environment so there are no body emissions.
Applications:
Liquid or gas where protection from flow reversal in a pipeline is required.
Construction:
The Wafer Double Disc Check Valves are constructed from rugged castings that are machined to exacting specifications. Reference individual technical data pages for standard disc, shaft, spring, and elastomer seat.
Installation:
Wafer Double Disc Check Valves are used in both vertical and horizontal applications. For horizontal flow applications the shaft should be vertically oriented. Contact RST for downward vertical flow installations.
Application standards:
- Design ASME B16.5
- Design ASME B16.34
- Testing API 598
- Conform to API594/API6D
- MSS SP-6
- MSS SP-25
- MSS SP-55
