DESCRIPTION
The E-CODA is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio.
OPERATION:
The E-CODA allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuirts.
FEATURES
* Product is not available with A and B spring ranges (4 and 15 psi (0.3 and 1 bar).
* Pressure at the port 2 area directly opposes pilot pressure.
* Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
* Maximum working pressure = 350 bar
* Leakage when valve closed = 0.07 ml/min.
