Check Valve
Ball Seat Valve
Metric Cartridge – 350 bar
RVM06020
Up to 38 l/min
Up to 350 bar
The check valve RVM06020 is a direct-
acting, spring-loaded ball poppet valve.
When there is no ow through the valve,
the spring holds the ball 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 together with the
pressure created by the spring force.
GENERAL
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 ow range
z All exposed surfaces zinc-plated and corrosion-proof
z Low pressure drop due to CFD optimized ow-path
z Optional version with hardened and ground seat
