Type S Check Valves

The Bosch Rexroth Type S check valve is designed for threaded and functions primarily to provide leak-free blocking in one direction. The valve is a spring-loaded isolator valve that allows flow in one direction once the selected cracking pressure is reached. These valves are available in sizes 6 through 30, with a maximum operating pressure of up to 450 bar (for sizes 6-20). They can optionally be ordered with a piston bore/orifice in channel B. The design and operating principle make it suitable for various hydraulic fluids, including mineral oils and bio-degradable types.
