EXPLOSION PROOF ELECTRIC ACTUATOR
Technical data
OHQ Series are explosion-proof, intelligent quarter turn electric actuators for the accurate control of valves with torques up to 2000 N.m. OHQ explosion-proof is designed for on/off or modulating control of butterfly, ball, rotary plug valves or dampers in a wide range of heavy industrial, chemical and petrochemical plants, water treatment plants, on and offshore. It can be driven by 380V/220V/110V AC power or 24V/110V DC power, inputs 4-20mA current signal or 0-10V DC voltage signal as control signal. (CE and EX certificates approved)
