Waircom Series XVF Complementary valve

The type “XVF4” identifies a 3/2 N.C. amplifier valve that changes low pressure signals into pneumatic signals (1 ÷ 8 bar).Valve type “XVF5” is instead a 3/2 N.O. amplifier valve that changes negative pneumatic signals into pneumatic signals (1 ÷ 7 bar). Both of them are suitable to pilot directly the valves series “UDS” and “UK” with the same mounting than solenoid valves series “UL”. For single mounting there is the sub-base type “XVB” (see on page 2.8) while for manifold mounting there are the bases type “ULP” (see on page 2.7).
