Direct-acting, pressure reducing valve
SERIES 1 / CAPACITY: 40 L/min. / CAVITY: T-11A
Direct-acting, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced
pressure at port 1. These valves incorporate a damped construction for stable operation allowing the use of high
reduced pressure.

TECHNICAL FEATURES
Note: This valve has no relieving capability. It should not be used in a dead-headed application. If the reduced pressure side of the circuit has very low leakage the
pressure may rise significantly. The pressure rise will vary from valve to valve.
For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.
