Product details

Pneumatic Eccentric Semi‑Ball Valve is a rotary‑type valve driven by a pneumatic actuator with an eccentric semi‑ball structure. The pneumatic actuator rotates the valve stem to turn the semi‑ball around the stem axis, achieving fast on‑off, shut‑off and flow regulation of process media.

Thanks to the eccentric design, the semi‑ball creates minimal friction against the seat during opening and closing. It features low operating torque, reliable sealing, excellent wear resistance and long service life. With a generally smooth flow passage, it is especially suitable for industrial piping systems handling complex media such as particles, slurry, wastewater, coal slurry and ash residue.

Pneumatic eccentric semi‑ball valves can be equipped with solenoid valves, limit switches, air filter‑regulator units, valve positioners and handwheel mechanisms. They can also be connected to automation control systems including PLC and DCS to realize remote automatic control.

Working Principle of Pneumatic Eccentric Semi‑Ball Valve:
Control signal → Pneumatic accessories → Pneumatic actuator → Valve stem rotation → Eccentric semi‑ball rotation → Valve On‑Off / Flow Regulation

Product Specifications

Pneumatic Shut‑off Ball Valve are 0‑90° rotary valves. They utilize pneumatic actuators to convert compressed air into rotary motion, delivering fast and reliable valve opening and closing for industrial process control.
According to specific application requirements, pneumatic ball valves can be equipped with solenoid valves, limit switches, position feedback devices, air filter‑regulators, valve positioners and other pneumatic instrument accessories to realize automatic valve control and remote monitoring functions.
Many factors shall be considered when selecting a pneumatic ball valve, including valve size, pressure rating, operating temperature, process medium, flow rate, body material, seat material, actuator type and control mode.
If you are looking for a qualified manufacturer or supplier of pneumatic ball valves, please contact our technical team and provide your operating conditions. Our valve engineers will recommend suitable pneumatic ball valves, actuators and control accessories based on your specific application requirements. (Unit: mm)
