Explosion integrated electric valve

Name: Explosion-proof electric valve Name: Explosion-proof electric valve Model: ZB941H-16 Specifications: PN2.5-320 DN15-180 describes the purpose and features: explosion-proof electric valve actuators (hereinafter referred to as electric apparatus) and YBDF series flameproof electric valve with Three-phase asynchronous motor assembly after a complete explosion-proof structure, explosion-proof performance in line with GB3836.2 "explosive environment with explosion-proof electrical equipment, explosion-proof electrical equipment" d "" provisions, proof mark dⅡBT4, applicable to the Class A Ⅱ , place class B, T1, T2, T3, T4 set of combustible gas and air to form an explosive mixture. DZB electric device can be directly related to the valve, closing valves, throttle valves and diaphragm supporting assembled into electric valve to be assembled into the secondary reducer DQB electric devices, and ball valve, butterfly valve supporting component electric valves. It can accurately control instructions by the opening and closing movement of the valve to implement remote control, centralized control and self-control. ◆ Main technical parameters: 1.
