UNOX 3 Pieces Flanged Ball Valve With Pneumatic Actuator

The UNOX Stainless Steel Flanged Ball Valve with Pneumatic Actuator – 3 Piece is a high-performance, automation-ready valve designed for industries that demand reliability, easy maintenance, and long service life. Constructed from AISI 304 or AISI 316 stainless steel, this 3-piece body design provides excellent corrosion resistance, making it ideal for chemical processing, food & beverage, pharmaceuticals, water treatment, marine, and steam applications.

The 3-piece body design allows the center section to be removed without disturbing the flanged pipeline connections, making cleaning, inspection, and replacement of seats and seals fast and cost-effective. The full-bore construction ensures maximum flow with minimal pressure loss, while the precision-machined stainless steel ball and reinforced PTFE/Viton seats guarantee bubble-tight sealing and smooth operation, even under continuous high-cycle service.

The pneumatic actuator provides reliable quarter-turn automation, available in double-acting or spring-return (single-acting) configurations. It can be equipped with limit switch boxes, solenoid valves, and positioners for seamless integration into modern automated systems. With a working pressure up to PN40 (≈580 psi) and a temperature range of −20 °C to +180 °C (≈ −4 °F to +356 °F), this valve delivers robust performance across a wide spectrum of industrial conditions.
