Description
A 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 INDC10-40 will block flow from port 1 to port 2, and from port 4 to port 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 port 4 is required at the pilot lines (ports 2 or 3) to open the flow passage to allow flow from ports 1 or 4. The check is spring-biased at 25 psi to assure holding in a static or no load condition. Note: Orifice disc cannot be used with this product.
