The Flowserve Edward Univalve® Piston Check Valve is small bore with a forged body and a body guided disc. This valve comes equipped with certain aspects and features that allow it to be proficient every time you use it. These features include:
- Minimized flow direction changes and reduced pressure drop due to an inclined stem construction with an optimum flow shape
- Eliminated misalignment, galling and stem bending by the use of anti-thrust rings in the body guided disc
- Positive shutoff and seat life provided by an integral hardsurfaced seat
- Ease of disassembly due to ACME threads being in the threaded bonnet
- Unwelded models use a graphitic gasket for dependable sealing. Welded models employ a fillet weld (canopy weld on stainless steel valves) for absolute protection from body-bonnet leakage.
- Reliable seal provided by a die formed, flexible graphite gasket seated to a prescribed bonnet torque
Available in class 1690, 2680 and 4500 in sizes 1/2 to 4 inches.
