Foot Valves are installed at the end of a suction line to prevent fluid in the line from draining when the pump is switched off, eliminating the need for re-priming at startup. Developed to provide reliable performance, these valves ensure positive seating at both low and high pressures without slamming.
Cast iron foot valves are commonly used on the suction side of pumps to prevent flow reversal from the pump back to the sump, helping maintain pump priming. They also act as a barrier against the entry of foreign matter into the pump through the suction pipe. Designed for use with clear water, these valves comply with the requirements of IS:4038 within the specified limits.
