Curved bill check valve
The Tideflex® TF-1 Check Valve from Red Valve features a bill that is formed into a curve that returns to a closed position every time, achieving the tightest possible seal for backflow operations, particularly at low flow rates. The eccentric, flat-bottom design allows installation where the invert of the pipe is close to the floor. The stronger engineered spine provides long-term performance while handling water weight.
