MODEL 3217 COMPENSATING SELF-RELIEVING AIR PRESSURE REGULATING VALVE

The 3217 is a mechanically actuated, sub-plate mounted regulating valve. It is both compensating and self-relieving, with an adjustable spring for setting the valve working pressure range. Movement of the spool stem into the valve produces a proportional output pressure, within the working range of the valve.

Materials: Die-cast silicon bronze and stainless steel hardware.
Maximum Supply Pressure: 250 PSI (17.24 BAR)
