Product Description


Industrial Stainless Steel Wafer Check Valve ( H71 )

• 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.
• Wafer Check Valves are available Solid Body, H-Body and Extended Body Designs in sizes up to 30". Body materials include Carbon Steel, 316 Stainless Steel, Cast Iron, Brass and Aluminum. Available elastomers include Buna N, EPDM, Viton, Silicon and PTFE. Valve internal components can be customized to fit your exact application requirements.
• Full Port, Lowest Pressure Drop. Full Port Wafer Check Valves provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve's open area and flow coefficient (Cv). They are ideal for application in vacuum pumps, compressed air and gas systems as well as in water systems where low head loss and elimination of water hammer are desirable.

Features:
 
1. Light weight,versatile design- 80% to 90% less than conventional full-body swing check valves

• Simplifies piping
• Reduces thermal and seismic considerations
• Optimizes space utilization
• Lowers installation costs
• Reduces pipe supports
• Requires less number of man-hours

2. Single Disc opening

• Unobstructed flow
• Stable disc at lower flow velocities

3. Single integrated arm/disc assembly Spring-loaded disc calculated to increase the responsiveness of the disc

• No shearing of disc from arm
• Non-rotating disc for longer life
• No nut to back-off disc stem

4. Elastomer o-ring seat secured in body with dove-tail groove

• Alleviates water hammer and resultant damaging effects

5. Integrated body seat

• Field replaceable seat
• Seat is out of the direct flow stream

6. Non-blow out shaft design

• Improved safety to personnel and surrounding equipment

7. Outside mounted accessories externally supported

• Increased control of valve performance
• Long body seal life
• Enhanced fugitive emissions control

 
Seat: NBR / EPDM / Viton / Metal. 

Competitive Advantages:
 

• Our products is guaranteed within 18 months after delivery.
