GB3836.1-2000 ZB (B) Small Flameproof Electric manual valve actuators automatic control
This series of valves explosion-proof electrical equipment (the explosion-proof electrical equipment) is a series ZB valve explosion-proof electrical equipment. Has flameproof marked d Ⅰ, dBT4. This series of explosion-proof electrical equipment with ZB Denso series of features: full-function, reliability and advanced control systems, small size, light weight, Qi, and other cha racteristics of different specifications.
The product perfo rmance to meet JB/T8528-1997 "common-valve electric device technology".Flameproof perfo rmance in line with GB3836.1-2000 "explosive environment with explosion-proof electrical equipment general requirements", GB3836.2-2000 "explosive environment with explosion-proof electrical equipment explosion-proof electrical equipment" d "" and JB/T8529-1997 " Valve explosion-proof electrical equipment technology ".
The series of explosion-proof electrical equipment fo r the valve flap valve in a straight line so the valve movement, such as the cut-off valves, valve, throttle, Valves, gates and so on. Can be used to bar out valve can be used to the dark bar valve, the valve is to achieve far-controlled, centralized control and automatic control of the essential drive.To rque output from the 50N? M to 400N? M (two sub-seat plane), the output speed of a 12, 18, 24, 30, 36, 42, 48, 60 r / min eight to choose from. Manual speed ratio of 1:1. Available to rque and thrust the two-connection size, respectively, in line with the standards and JB2920 standard ISO5210. Trip controller can be expanded to four locations (opened, customs, in 1, 2). Valve position transmitter (4 ~ 20mA current output) as an annex fo r selection.
