Champion Valves Inc. Wafer Style Spring Loaded Dual Disc Check Valves are retainerless, self-operating valves with two discs that open to 85 degrees to allow media to flow through, alleviating potential of water hammer and pressure loss.
These dual-disc valves are suitable for
the following kinds of applications:
-
General service piping systems
-
Water, oil, gas
-
Compressed air and blowers
VALVE FEATURES
Lightweight, Versatile Design: The short lay-length of these check valves allows for an 80-90% reduction in weight compared to conventional full-body swing check valves. This reduces initial costs and helps to minimize space requirements for an easy installation.
​Reduced Pressure Loss: These check valves open to 85° in the full-open position. This minimizes the pressure drop across the valve by promoting a smooth, low-turbulent flow path to allow working fluid to transition through the valve without sustaining unnecessary losses.
Minimized Water Hammer: Spring-loaded discs close automatically at near-zero flow velocity conditions. This minimizes the surge from reverse velocity that can cause damaging pressure waves to be transmitted to the valve, pump or compressor, and other system components.
Spring Selection: Springs are available in various torque options to promote system performance optimization and to allow for various flow orientations.
