The Duo-Chek wafer valve design is generally stronger, lighter, smaller, more efficient and less expensive than conventional swing check valves. Its design meets API 594 which is approximately one fourth the face to face dimension and 15 to 20 the weight, on most popular sizes, making them less expensive than a swing check valve. It is much
Check valves having springs with rated crack pressures of 3 psig 0.21 bar or less may require up to 4 psig 0.28 bar back pressure to re-seal bubble-tight. Note Check valves which are not actuated for a period of time may initially crack at higher than the above crack pressure ranges.
The Access chamber has a pre-installed WaStop valve. The WaStop module is removable from ground level for easy maintenance. Available in NPS 4 , NPS 5 and NPS 6 . Please refer to drawings for more information. The following technical information relating to WaStop inline check valves
The simplest test for a ball check valve is to pressurize the valve and measure the leakage. For hydraulic valves, it is not uncommon for the test specifications to give a maximum number of drops per minute and for gas, the number of bubbles, at a given pressure that is an acceptable leakage. This method may not be appropriate for several reasons.

Check Valve Manufacturer. Check valves are mechanical devices that permit liquids and gases to flow in only one direction, preventing flow from reversing. They are classified as one-way directional valves meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
Parker provides the industrys widest selection of check valves, available in a variety of end connections. Our valves are used in a diverse range of applications, from air and fuel systems to load holding.
