1903 Valstop Brass Spring Check Valve Viton Seals
A high quality spring check valve with a robust brass body and Viton® seal for superior leakage protection when line pressure drops and the valve isolates upstream equipment, protecting it from unwanted flow reversal. The streamlined high flow capacity design provides quiet operation, reduction in water hammer and minimal head loss within a wide range of working pressures and temperatures in non-potable water applications.
