[Shifting fork pneumatic actuator]- whether it is a double-acting pneumatic actuator or a single-acting pneumatic actuator, the main internal structure is the piston, ball, fork, its role is: when the gas When entering the cylinder, push the piston to slide, drive the ball to slide, drive the fork to rotate, and the rotation of the fork drives the rotation of the shaft to realize the opening and closing of the valve!
The main difference between double-acting pneumatic actuators and single-acting pneumatic actuators is that double-acting pneumatic actuators have no spring parts. In this case, there is no way to reset the valve to the closed state in the event of a sudden power outage or gas outage! This is a very serious situation in the chemical industry or the petroleum industry, so if you need to encounter a sudden fault reset, choose a single-acting pneumatic actuator!
Shift fork pneumatic actuators are now widely used, mainly used with various valves to realize automatic opening and closing of valves! It is used in the fields of petroleum, chemical industry, electric power, metallurgy, pharmaceuticals, food, water treatment, municipal water supply and drainage, natural gas, papermaking, electronics industry, buildings, machinery and equipment, etc.!
