ZC FLAMEPROOF TYPE ELECTRIC VALVE ACTUATORS  ZC350B ～ ZC1000B

This series flameproof electric valve actuators (flameproof actuator as abbreviation) are explosion-proof type  of  series  ZC  electric  valve  actuators.  Types  ZC45B～ZC250B  are  single  unit  actuators  and  Type ZC350B～ZC1000B are combination set of an actuator and a gear reducer. Flameproof marks are divided intodⅠ, dⅡBT4 and dⅡCT4. This series flameproof actuators are provided with features of series ZC actuators: of full functions, advanced in control system, small in size, complete in specifications. The performance of flameproof actuators conforms to Std JB/T8528   SPECIFICATIONS  OF  ELECTRIC  VALVE  ACTUATORS OF COMMON TYPE. Flameproof  performance  of  these  products  conforms  to  Std  GB3836.1—2000  ELECTRICAL APPARATUS FOR EXPLOSIVE ATMOSPHERES-- GENERAL REQUIREMENTS and Std GB3836.2-2000 ELECTRICAL  APPARATUS  FOR  EXPLOSIVE  ATMOSPHERES—FLAMEPROOF  ELECTRICAL APPARATUS“d”  and  Std  JB/T  8529—1997  TECHNICAL  SPECIFICATIONS  OF  FLAMEPROOF ELECTIRIC VALVE ACTUATORS. This series flameproof electric valve actuators are suitable to valves of which the clacks move linearly, such as globe valves, gate valves, throttle valve, diaphragm valve etc. They can be used for rising stem valves and non-rising stem valves as well. They are necessary devices to carry out remote control, centralized control and automatic control of valve.
