Directional valve


MCODA


Features Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss. 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.

Features
Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi
(70 bar) at the pilot port will close a valve against a pressure of
1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could
allow the valve to open, even if it is a momentary decay or loss.
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.
Operation
This valve is a spring biased closed, pilot-to-close check cartridge that has
a 1.8:1 pilot ratio. The valve 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 circuits.
