Over twenty years of field operation, research, development and engineering enhancements have combined to make the Tideflex TF-1 Check Valve today’s most reliable check valve. The bill 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. When you specify the patented TF-1 Check Valve, you are guaranteed a proven record of maintenance-free backflow prevention.
