Additional Valve Information
Note: The Dale series pressure controlled valves require both an
external pilot supply and a control signal to operate the valve. When a
pressure control signal is applied the valve shifts to the open position.
The LF & LX Advantage
The LF & LX Series provides superior performance
over a diaphragm valve with a rugged poppet
design, bi-directional flow and high cycle life.
External Pilot Supply
Pressure Control Signal
X-1
The LF & LX Series provides superior
performance over a ball valve with solenoid
actuation, shifting speed, cycle life, and most
important, a cost effective alternative.
