Product Name Notes
Relief/Sustaining/Surge Control Valves -- A106-DL The Dynamic Lifter pressure relief valve is a direct acting spring loaded relief valve. The valve is adjusted to open when the pressure exceeds the set-point, and closes drip-tight when...
Relief/Sustaining/Surge Control Valves -- 106/206-RPS-RR The valve is installed downstream of the pump check valve(s) and has two pilots.The high pressure pilot acts as a standard relief pilot, opening on excessive pressure. The differential pilot...
Relief/Sustaining/Surge Control Valves -- 106/206-RPS-L&H The valve is mounted in a tee, downstream of the pump check valve(s). It is designed to anticipate surges to avoid the severe water hammer often associated with power failure...
Relief/Sustaining/Surge Control Valves -- 6/206-RPS-Relief This unit senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting. The valve opens...
Relief/Sustaining/Surge Control Valves -- 106/206-RPS-SUSTAINING This unit senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the inlet pressure exceeds the pilot setting.Should the upstream pressure...
Relief/Sustaining/Surge Control Valves -- 106/206-RPS-D This valve and has two sensing connections. The valve and pilot remain closed until the difference between the two pressures exceeds the pilot setting. The pilot setting establishes a differential...
Relief/Sustaining/Surge Control Valves -- A106-DL-AI/A106-DL-ET This valve is a compact relief valve that is suitable for high pressures up to 200 psi. Utilizing compressed air this valve Eliminates surges, and prolongs pipe life. Product Information:...
