DESCRIPTION
A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.
OPERATION:
The E-YDF04-00 allows flow 2 to 3 with very low pressure drop, while blocks flow from 3 to 2. The valve blocks flow from 3 to 2 until sufficient pressure is applied at 1. The valve has a 2.2:1 pilot ratio, meaning that at least 1/2.2 of the load pressue held at 3 is required at 1 to open the valve.
FEATURES
* Hardened seat for long life and low leakage.
* Optional sealed piston.
* Optional spring ranges.
* Compact size.
