Check Valve
Design Features
The U32 check valve is available in lift and swing configurations with hard alloy sealing surfaces, ensuring reliable backflow prevention compliant with ANSI Class VI leakage standards. Automatically actuated by media pressure, it operates securely across extreme temperatures from -196°C to 610°C. Its wear-resistant seal withstands erosion and thermal cycling, making it suitable for critical service in oil and gas, power generation, chemical processing, and cryogenic systems. Custom configurations for specialized requirements are available upon request.
