API/DIN Standard Stainless Steel Dual Plate Wafer Type Check Valve
Dual Plate Wafer type Check Valve, sometimes people also call them as door valve, its shape like a door. There are two parts of disc, they combine with a spring, when fluid come, they will open in two direction like a door. So spring is a very important part for wafer type check valve. Wafer type check valve, could prevent reverse of fluid of medium. But generally speaking, wafer type check valve can not bear very high pressure, PN16~PN40 is ok. Wafer type check valve is a kind of automatic valve, no need to use handle or gear to control open and close. It is a kind of one way valve, fluid only could flow in one direction. There are three types of wafer check valve, one is swing type, lift type and butterfly type.

Features:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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
