Actuator type DA/SR series, GTE GTD/series, QGSY series, etc
characteristics
1, fire prevention, antistatic design 2, stem explosion-proof out 3, the design on the device steel ball pressure balance hole 4, double stem packing and two pieces of dish type device 5, which the body in the design of the body cavity clean device
use
Electric ball valve is a corner for 90 degrees of rotation class ball valve, good sealing, circulation ability, the resistance to flow coefficient is small, simple structure, convenient maintenance, long service life, body channel and connection pipe diameter and equal into a diameter, medium can be without a loss of almost pebbles. With Ⅱ DKJ-Ⅲ actuators, led with Japan tooling, west Germany omron and high performance actuators. Products commonly used for sealing strict for occasions, in addition to control gas, liquid, steam medium outside, still appropriate control sewage and contain fiber of the impurities of the medium, widely used in oil, chemical industry, metallurgy, light industry, paper making, power stations, refrigeration work areas. Ball valve is a kind of important valve class, in the petroleum chemical industry, the long distance pipeline and other fields have a widely used. Ball valve closed a is a with hole sphere (or part of the ball), ball with stem rotation, the realization of the valve open or closed.
Ball valve rotates 90 degrees can fully open, and sexual same specifications of gate, globe valve comparison, ball valve small volume, light weight, easy to installation of pipes
