HEK VLVE heck Valve pplication Swg check valves are designed to close quickly and automatically with positive shut off either horizontal or vertical (flow up) pipe runs. Inherently, swg check valves have a low pressure drop and are best suitable for velocity applications. Our closure design allows our swg check valve to close completely even and rema closed with no flow when stalled a horizontal pipe run.

The disc is secured to the hge arm with the disc nut and pned to prevent disengagement durg service. Seat rgs are designed to greatly reduce and/or prevent any turbulence and avoid damages due to the corrosion. Seat rgs for gate valves are typically made from forged steel.
