PMISO valves:
born to be motorized

Technically designed and made to guarantee the highest level of functionality and torque performance.

EXCELLENT TIGHTNESS

under high pressures thanks to the two/four PTFE seats with damper O-rings which soften the valve manoeuvre by reducing the torque, thus aiding the role of the servomotor.

PRESSURE

PED 2014/68/EU certified valves – class PN40 bar

STRUCTURE

two/four kits (gasket + O-ring) around the ball in order to be perfectly centered and stopped

PUSHROD

thanks to O-rings, they are leak-proof. Teflon doesn’t generate attrition
