Check Valve
Poppet Type
Cartridge – 350 bar
RVM10120-51
up to 100 l/min
up to 350 bar
The check valve RVM10120-51 is a direct-
acting, spring-loaded poppet valve.
When there is no ow through the valve,
the spring holds the poppet in the closed
position and therefore shuts off port 2 from
port 1. The valve opens when the
pressure at port 1 is higher than the
pressure at port 2 including the pressure
created by the spring force.
GENERAL
z High performance version for high cycle rate
z Main application is to prevent uncontrolled movement or creeping of loaded
cylinders and also to isolate sections of the system
z Excellent stability throughout the entire ow range
z All exposed surfaces zinc-plated and corrosion-proof
z All valve parts made of high-strength steel with hardened and ground components
to ensure minimal wear and extended service life
z Low pressure drop due to CFD optimized ow-path
z Improved water resistance, achieved by guided and dampened piston
