2022 Good Quality Electronic Solenoid Valve - Valve gear box/Electric actuator/Pneumatic actuator – BESTOP

Size:2”-80”
Type:Single-stage,Double-stage and BA series Multi-turn actuator
Workable torque(N.m):150N.m to 63000N.m
Material:Die-casting aluminum,Cast iron

Description:
A reduction device driven by human force to reduce the force required for manual operation of the valve is usually available in two types: multi-turn and partial turn. It is characterized by simple structure and easy operation. It is commonly used to drive valves with nominal diameters less than 300 mm.
Gear transmission device is the use of two gear teeth meshing with each other to transfer power and movement of mechanical transmission, with the master and slave driven wheel teeth directly, transfer motion and power.According to the relative position of the gear axis, it can be divided into parallel axis cylindrical gear transmission, intersecting axis bevel gear transmission and staggered axis helical gear transmission. It has the characteristics of stable transmission, accurate transmission ratio, reliable work, high efficiency, long life, large power, speed and size range.

Description:
Electronic Actuator is a kind of instrument used in all kinds of industrial automation process control links. The electric actuator has the characteristics of safety guarantee, protection device, various speed, corrosion and rust prevention, intelligent numerical control and so on.
Compared with hydraulic and pneumatic products of the same function, the electric actuator has the highest cost performance. The electric actuator (electric push rod/cylinder) is cleaner, easier to operate, and has higher power efficiency. Users can benefit from this. The integrated design of the electric actuator makes it easier to program and control, and minimizes the maintenance effort, except in extreme conditions, without the need to reacquire or lubricate parts.

Installation dimension:ISO5211,ASTM,GB standard and client’s requirement is available.
Notes: Torque as per client’s requirement is available.
Description:
Pneumatic actuator is an actuator that uses air pressure to drive open, close or adjust the valve. It is also known as pneumatic actuator or pneumatic device, but it is commonly known as pneumatic head.
Pneumatic actuators are sometimes equipped with certain auxiliary devices. Commonly used are valve positioner and handwheel mechanism. The function of valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can achieve accurate positioning according to the control signal of the controller. The function of handwheel mechanism is when the control system due to power failure, gas stop, controller no output or actuator failure, the use of it can directly operate the control valve, in order to maintain the normal production.
Pneumatic device is mainly composed of cylinder, piston, gear shaft, end cover, seals, screws, etc. The complete set of pneumatic devices shall also include opening indication, travel limit, solenoid valve, positioner, pneumatic components, manual mechanism, signal feedback and other components.
