Pressure Relief valves are used to limit the pressure in the system as set on the valve. Direct Relief Valves are applicable in systems where quick pressure release is of prime concern for safety. This is an economical solution for systems having small flows. The valve is a zero leak valve due to the metal sealing of the poppet on the seat. The C175 can also be used for pilot systems.
As with all direct acting pressure relief valves, when the pressure at the inlet (P) exceeds the spring force set by the adjuster, the poppet moves back, opening the inlet (1) to outlet (T). This relieves the pressure to tank. The dampening buffer on the nose of the valve dampens the vibrations caused by pressure variations on the valve. This gives it a smooth opening and closing characteristic with minimum chatter.
Matched ground and hardened working parts give a long and trouble-free life. Consistent stable operation providing low pressure over ride even with increasing flows. Cartridge type construction gives maximum flexibility in mounting.
