Pneumatic Internal Thread Ball Valve
The Pneumatic Internal Thread Ball Valve uses a threaded connection for compact installation. Its 90° quarter-turn ball and corrosion-resistant construction handle granular, viscous, or corrosive media. Common in petrochemical, power, pharmaceutical, and food applications. Optional positioners and solenoid valves add remote automation and emergency shut-off.
Features
- Multi-position mounting; flow-direction independent.
- Simple construction, easy operation, cost-effective.
- Compact, rugged design for demanding service.
- Integrated self-cleaning keeps pipelines free-flowing.
