ZB60-ZT explosion-proof electrical equipment

Multi-turn valve actuators, known as Z-type. Valve is suitable for the valve so linear motion, such as gate valves, globe valves, diaphragm valves, water gates and the like. For the valve open, close or adjust the valve to achieve remote control, centralized control of the essential drive and self-control. They have a full-featured, reliable performance, advanced control system, small size, light weight, ease of use and maintenance. Widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other sectors. The performance of the product in line with JB / T8528-1997 "common type valve electric device technology" requirements. Explosion-proof performance in line with GB3836.1-83 "explosive environment with explosion-proof electrical equipment General requirements", GB3836.2-83 "electrical equipment for explosive atmospheres flameproof electrical equipment" d "" and JB / T8529-1997 "spacer provisions implosion-type valve actuators technical conditions ". Smart electric modulating device receives DC4 from DCS or PLC systems controller ~ 20mA standard current signal, control electric actuator complete proportional valve opening degree of regulation. The product set phase sequence automatically adjusted, proportional control, isolation amplifier, valve position transmitter, power driver and many other functions and one with phase protection, over-torque protection, electronic interlocking protection, move ban delay protection, lost letter protection temperature protection, complete protection. Also increase with the scene button version, the implementation of field operations and provide a variety of alarm output; increase with the valve-digit LCD display, precise visual indication of valve opening; increase with an infrared remote control, to achieve a higher degree of protection of the field operation. The product has anti-interference ability, reliable performance, seismic, moisture, small size, wiring, easy debugging, etc., by the majority of users.
