Jining Dongda Mechanical and Electrical Equipment Co., Ltd.

Product introduction of intrinsically safe pneumatic solenoid valves for mine control switches
The use of intrinsically safe pneumatic solenoid valves (coal safety certificate number) is based on the requirements of the "General Technical Requirements for Electrical and Electronic Products for Coal Mine Communication, Detection, and Control" Designed and manufactured, mainly used for automatic control of pneumatic equipment in coal mines.
Structural composition of intrinsically safe pneumatic solenoid valve for mine control switches
The solenoid valve is composed of a valve body and a valve head. The opening and closing of the solenoid valve is sensitive, and the action is quick and reliable (the action time is less than) Wiring Simple and easy to maintain.
It can be connected with pneumatic equipment such as damper device, control switch device, sports car protective device, etc. to realize automatic control.
