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.
