NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.
This valve is a 3-way, normally open modulating element that incorporates an integral pilot control cavity. The pilot
control cavity will accept any T-8A pressure control cartridge. The valve reduces a high primary pressure at the inlet
(port 2) to a constant reduced pressure at port 1, with a full flow relief function from port 1 to tank (port 3). The pilot
cartridge's setting determines the difference in pressure between reduced pressure (port 1) and the tank (port 3).
