3/2 Way Diaphragm Control Valve

For Thermic Fluid & High Temperature Applications (Up to 450°C)

The Uflow 3/2 Way Pneumatic Diaphragm Operated On/Off Valve is specifically engineered for demanding applications involving thermic fluids, steam, gas, and water at elevated temperatures. Designed to operate reliably at temperatures up to 450°C, this valve offers high performance, long service life, and tight shutoff capabilities in extreme conditions.

Built with metal-to-metal sealing and constructed from high-grade materials such as WCB, CF8, or CF8M, the valve ensures excellent resistance to thermal stress and corrosion. The stainless steel trim (SS304/316) further enhances durability in high-temperature operations. Its pneumatic diaphragm actuator allows for smooth, responsive operation and requires minimal maintenance.

The valve meets international standards such as BS 6697, ASME B16.5, ISA 75.03, and IEC 534-3, and is IBR approved, ensuring its suitability for critical industrial systems.
