HVAC Check Valves
American Wheatley HVAC Check Valves are engineered for silent operation and even little head loss. The Wafer Style Non-Slam Check Valve will automatically prevent your system from experiencing a back-flow, when your system is desired to flow in one direction only and keep the flow from moving in the opposite direction. The disc in this valve will open automatically, as soon as the pump begins the downstream flow, providing the amount of pressure required to move in the forward direction. The disc is also going to close automatically, when the pump has stopped and the flow has started to slow down – closing before the reversal of the flow. This ensures that the reversal of the flow was positively shut off.
