Pneumatic Thin-Pattern Ball Valve
Ultra-thin design for installations with limited space.
Product overview
This pneumatic thin-pattern ball valve covers DN15~200 and multiple pressure classes under Chinese, US and Japanese standards. Various body and seat materials are available. The short, lightweight wafer construction significantly reduces installation space. A raised top platform directly accepts a full range of automation accessories for compact equipment piping layouts.
Available with double-acting and single-acting spring-return pneumatic actuators; the single-acting version returns automatically on air loss. It supports on/off shutoff and proportional control, with a valve positioner for precise flow regulation. Widely used in chemical, power, water-treatment and oil and gas pipelines. Rapid response and stable torque make it a preferred valve for switching and regulation in confined spaces.
