Cast Iron Globe Valve J41H-JGPV Flanged Design 15-600mm DN 1.0-10.0 MPa Pressure Rating

The J41H-JGPV globe valve, also known as a cut-off valve, features forced sealing design with vertical stem axis alignment to the valve seat sealing surface. This industrial valve operates by driving the spool up and down for precise flow control and reliable shut-off functionality.

• Superior Sealing Performance: Single sealing surface design with reliable cut-off function and excellent manufacturing technology
• Compact Design: Small disc travel height (25-30% of nominal diameter) with minimal space requirements
Working Temperature Up to 200°C Connection Type Flange Operation Methods Hand-wheel, bevel gear, pneumatic, electric actuators
Key Features & Benefits
• Superior Sealing Performance: Single sealing surface design with reliable cut-off function and excellent manufacturing technology
• Compact Design: Small disc travel height (25-30% of nominal diameter) with minimal space requirements
• Extended Service Life: No contact between seat and disc sealing surfaces in open state reduces wear and extends seal durability
• Precise Flow Control: Proportional relationship between valve seat opening and disc stroke enables accurate flow regulation
• Industrial Applications: Suitable for petrochemical, power generation, metallurgy, urban construction, and chemical processing industries
• Multiple Operation Options: Available with hand-wheel, bevel gear, pneumatic, or electric actuator controls
Operation Characteristics

The globe valve achieves maximum flow when the opening height reaches 25-30% of the nominal diameter. The stem operates with relatively short open/close strokes, providing reliable shut-off capability. When closed, pressure applied to the disc ensures complete sealing surface contact to prevent leakage.
