DESCRIPTION

The E-DC10-40 is a cartridge style, dual pilot operated check valve for use in blocking or load holding circuits. This valve has an optional thermal relief from port 4 to port 3. 

 

OPERATION:

The E-DC10-40 valve will block flow from 1 to 2, and from 4 to 3. Flow is allowed in the opposite direction when pressure is applied to port 2 and/or port 3. 
The valve has a 3:1 pilot ratio, so at least 1/3 of the load pressure at port 1 or 4 is required at the pilot lines (ports 2 or 3) to open the flow passage to allow flow from ports 1 to 4. 
The check is spring-biased at 25 psi to assure holding in a static or no load condition. 

FEATURES:

l  Hardened seat for long life and low leakage.

l  Low pressure drop.

l  Optional thermal relief.
