DESCRIPTION
E-CR10-28 is a screw in, cartridge style, direct-acting, differential area, poppet type, bidirectional hydraulic relief valve.
OPERATION
The E-CR10-28 is a direct-acting, dual cross-over relief valve in a single cartridge format. When pressure at either port exceeds the nominal setting value, flow will be transmitted to the opposite port. Back pressure at either port will affect the nominal setting of the opposite port on a 1:1 basis. For correction purposes, pre-set value will be measured at port 2. Pressure at port 1 will not exceed ±150 psi from the port 2 value.
FEATURES
* Adjustments cannot be backed out of the valve.
* Adjustments prohibit springs from going solid.
* Hardened parts for long life.
* Industry common cavity.
