Hydraulic Symbol
Description
A screw-in, cartridge-style, direct-acting, poppet-type, hydraulic relief valve intended for use as a pressure limiting device for common hydraulic circuit protection.
Operation
The valve prevents flow from port 1 to port 2 until the set crack pressure at port 1 is achieved. The poppet then unseats, allowing flow from port 1 to port 2, protecting the circuit from over pressurization.
