Valves

Description
Technical data
Pumps in single-line systems can be supplied and actuated with
compressed air via servo-controlled, 3/2-way piston valves (mag- Function principle 3/2-way solenoid air valve with
netic valve). For function and operation of the valve, a minimum dif- servo piston
Initial state outlet A open
ferential pressure of 0,5 bar is requested. The valve is equipped with Operating temperature –10 to +55 °C
a control for initiation and check of function. Currentless, the valve is +14 to +131 °F
Operating pressure 0,5–16 bar;
open to outlet A. It has a smooth-running servo piston. A 3/2-way 7.3–232 psi
pilot valve (tilting armature valve) provides safe and reliable Supply voltage
