43307005700000 Rexroth check valve
delivery time：4 days
Description
When pressure at 2 rises above the spring bias pressure, the
poppet is pushed from its seat and flow is allowed from 2 to
1. The valve is normally closed (checked) from 1 to 2. When
sufficient pilot pressure is present at port 3, the pilot piston
acts to push the poppet from its seat and flow is allowed from
1 to 2. Precision machining and hardening processes allow
virtually leak-free performance in the checked condition.
In case of valve application in redundancy systems it is
especially recommended to use version with sealed pilto
piston
