Detail
1. Characteristic:
Two-position three-way electronically controlled shut-off valve is a kind of end-sealed shut-off type directional valve, with "normally closed" and "normally open" two structural forms. This series of valves have low air purification requirements, strong dust resistance, and a wide range of specifications and diameters. Commonly used to control single-acting cylinders and diaphragm cylinders and other actuators, but also a large number of program control air circuit. If blocking the exhaust port, can become a two-position two-way switch type, some large bore double-acting cylinder, often not easy to solve the diameter of more than 32mm two-position five-way valve, at this time, can be used a normally open and a normally closed two-position three-way stop valve joint control to solve this problem.
The series of valve bore 6 to 25mm for the plate connection, more than 32mm for the flange connection.
