Pneumatic thin ball valve

Highlight: Pneumatic thin ball valve

Product introduction:

A pneumatic thin-type ball valve is a valve where the ball rotates 90° around an axis perpendicular to the channel. It consists

of a piston-type double-acting or single-acting (spring-return) pneumatic actuator and an O-type valve structure. Equipped

with accessories such as solenoid valves, air filter regulators, limit switches (valve position indicators), or electro-pneumatic

valve positioners, it enables automatic regulating control or on-off (two-position) cutoff control of fluid media in process

pipelines.

Product features:

1. Pneumatic ball valves have low fluid resistance, being the smallest among all valve types. They can be quickly and

conveniently opened/closed, using compressed air as power to drive the valve stem through a piston rack and gear

mechanical transmission, rotating the ball 0-90° with torque output in angular stroke to rapidly complete opening/closing or

regulating actions. The ball core channel is flat and smooth, less prone to medium deposition, allowing pipeline pigging. It

features a simple structure, light weight, and good sealing performance, serving as an actuator unit for instruments in

automatic control systems.

2. Equipped with an electro-pneumatic valve positioner, using electrical signals and compressed air as power, it accepts

0-10mA DC or 4-20mA DC current signals input by the control system. The regulator converts compressed air into air

source pressure signals for input/output, changing the rotation angle of the ball core to achieve proportional regulation.

3. With solenoid directional control valves and valve position indicators, using AC220V or DC24V power supply and

compressed air as power, it realizes fast on-off (two-position) cutoff control of fluid media.

4. The pneumatic actuator adopts a piston-type cylinder and crank arm conversion structure, offering large output torque

and a compact size. It uses a fully sealed waterproof design with a high protection level. The cylinder body is a mirror-

finished cylinder for oil-free lubrication, featuring low friction coefficient, corrosion resistance, and super durability/reliability.

All transmission bearings use boundary self-lubricating bearings for oil-free lubrication, ensuring no wear on the drive shaft.
