    it reduces the torque actually required to open and close the gate at high pressure.

    Pump suction pressure is 58 bar but the process pressure is 85 bar is the pump under rated?

    Worm gear actuators have the advantage of easing the manual opening and closing of valves, generally quarter-turn valves, without opting for more expensive pneumatic, hydraulic or electric actuators. Worm gears are intertwined in such a way that each gear reduces torque, and the combined torque reduction across all worms can be so substantial as to allow the manual operation of even quite large ball valves.

    Generally a relief valve will automatically reset and close once the pressure has been reduced. A safety valve is usually valve which operates once or must be manually reset following an over pressure event.

    This distinction is not absolute, since these valves perform the same basic function.
