Overview
The Conval 12U2J-F228H-6T14 globe control valve delivers precision flow and pressure regulation in demanding industrial, pneumatic, and hydraulic systems. Manufactured by Conval Inc., a recognized leader in high-pressure valve technology, this 2″ valve features an ASME 2155 intermediate pressure rating with an SA 182-F22 alloy steel body—a proven material for elevated-temperature and corrosive service. The 30 LBS pressure rating and modular design enable in-line repairability while maintaining system integrity across thermal cycles.
Key Features
- Pressure Seal Bonnet: Easy access for servicing without welding or gasket replacement
- Axial Design: Ensures tight concentricity, eliminating side loading and minimizing wear on trim components
- Modular Construction: Common parts across valve sizes reduce spare parts inventory
- ASME Intermediate Rated: Certified for ASME 2155 pressure class with F22 material compatibility
- In-Line Renewable: Pressure-actuated backseat isolates packing from main pressure when fully open, extending component life

- Flow throttling and pressure regulation in process piping
Compatibility & Replacements
Compatible With
- ASME piping systems rated for Class 2155 pressure
- Pneumatic and hydraulic control systems operating at 2155-class pressures
- Actuator systems (electric, pneumatic, or hydraulic) compatible with 2″ globe valve bonnets
- Standard piping end connections (verify flange type and connection method with system integrator)
- Maintenance protocols requiring in-line renewal and pressure-seal bonnet access
Replaces / Drop-In Replacement For
- Verify replacement suitability with your system integrator or Conval technical support; globe valve interchangeability depends on exact bonnet, trim, and end-connection specifications.
Works With
- Conval Clampseal® modular valve ecosystem (common spare parts)
- ASME B16.34 piping standards and flanged/threaded systems
- Pressure-seal bonnet design (no welding or custom sealing required for maintenance)
- Pneumatic, electric, and manual actuation methods
