Stamping handwheel is widely used, today to understand the pneumatic ball valve is used for what? In simple terms, it's for explosion protection. Generally, the handwheel with manual operation is used to prevent emergency switch in the case of power failure or death. The stamping handwheel equipped with manual operation can effectively prevent accidents in the case of no air source and power supply. The valve switch can be controlled by the manual handwheel device.
Don't look down upon these valves accessories, under this critical moment can play an important role, with manual stamping the handwheel explosion-proof pneumatic ball valve by pneumatic actuators, manual switch gear, ball valves and related explosion-proof accessories, such as: explosion-proof solenoid valve, explosion-proof limit switch, air source treatment sanlian pieces and so on, through configuration of different control accessories, which can realize remote control, fast cutting off and regulating function, is suitable for inflammable and explosive dangerous environment, such as gas, liquid, dust, widely used in the petroleum, chemical industry, metallurgy, electric power, pharmaceutical, paper making, water treatment, food, construction and other fields.
Pneumatic ball valve with manual (hand wheel) explosion-proof by 0.4 0.7 MPa clean air source can control valve operation, and sent two for passive contact signals indicating valve switch, and execution speed is relatively fast, realize the local control and remote centralized control, in the control room can control the switch of the valve, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time, improve the security. Small wheel big role, safe production, life first.
