Explosion-proof part of the rotary valve intelligent integration of DQ-TB electric device for medium and small diameter of the butterfly valve, ball valve, and so do 90-degree rotation of the valves and other similar devices. Protection class IP65 (up to IP67), as a reliable rotary electric actuator, DQ series valve actuators and reliable design, suitable for different control coefficients, different working environment. 
 This series Denso user installation, commissioning, maintenance is very convenient, saving installation costs can be greatly shorten the installation cycle, continuous operation can be on-site button can also be remote control, centralized control and automation, internal phase sequence identification and lack of protection function. 
 Overview 
 Part of the rotary valve actuators, collectively referred to as Q-type electrical equipment. To achieve the valve open, close or adjust the drive control device for butterfly valves, ball valves, plug valves and damper, and so do 90 ° rotation of the valve. 
 This series of electric remote control device can also be on-site operation. Widely used in electric power, metallurgy, petroleum, chemical, food, textile, paper, pharmaceutical, water and sewage treatment industries. 
 This product's performance in line with JB/T8528-1997 "common type valve electric device technology" requirement; explosion-proof performance consistent with GB3836.1-2000 "Electrical apparatus for explosive gas atmospheres Part 1: General requirements", GB3836 .2-2000 "Electrical apparatus for explosive gas atmospheres Part 2: Flameproof" d "" and JB/T8529-1997 "explosion-proof valve electric device technology" requirements. 
 Part of the rotation type of electrical device according to the structure is divided into Q-and DQ type. Q-type structure as a whole, DQ-type structure for the overlay (multi-turn electric device + two gear box). 
 According to type of protection can be divided into outdoor type and explosion-proof type. 
 Press control can be divided into conventional type, the overall type and overall adjustment type.
