Normally closed pressure regulating valves; when pressure at port 1 reaches the valve setting, the valve starts to open to port 2, throttling flow to regulated the pressure; port 3 connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves; valves are accurate, have low pressure rise vs flow, smooth and quiet, and moderately fast; capacity is 30 gpm; valve hex size 1 1/8 in; valve installation torque 45-50 lbf ft
A valve designed to automatically release excessive pressures. It is actuated by static pressure upstream of the valve and is used as a safety valve or relief valve, and may be set to close at a predetermined pressure. It is not designed for regulation of continuously fluctuating loads. It may be inline or cartridge (manifold) design. Excludes valve (1), relief, pressure and temperature.
Classification: Safety or relief valves
