J-VALVES
Design Features
Integral Forged Valve Body:Machined from solid forgings including A105N, F11, F22, F91, F92, F304, F316, etc. Featuring dense metal structure without casting defects, excellent mechanical properties, and significantly better creep resistance and fatigue resistance than castings. Suitable for high-pressure and alternating load conditions.
Butt Weld Connection (BW):Full-welded butt weld connection between valve body ends and pipelines, complying with ASME B16.25. No flange sealing faces or bolted connections, completely eliminating leakage risks at joints. Compact structure and high pressure-bearing capacity, ideal for critical high-pressure systems.
Pressure Self-Sealing Bonnet:Pressure self-sealing structure (wedge gasket, octagonal gasket or lens gasket) between bonnet and body. The higher the medium pressure, the more reliable the sealing. Adapts to thermal expansion and contraction cycles under high temperature and pressure, preventing thermal relaxation leakage. Compared with bolted flange bonnets, it significantly reduces external leakage risks and maintenance workload under high pressure.
Wedge Gate:Flexible or rigid wedge design, automatically compensates for sealing face wear, suitable for general high-pressure applications.
Parallel Double Discs:Spring preload between two gates enables bi-directional sealing, suitable for high-temperature and high-pressure steam and applications requiring tight shut-off.
Hardfaced Sealing Surfaces:Sealing faces of seats and gates are hardfaced with Stellite or other hard alloys, providing high temperature resistance, erosion resistance and wear resistance, extending service life.
Rising Stem Design:Stem rotation drives gate lifting. Non-rising stem is optional (stem stationary, gate lifting only), reducing packing wear and improving sealing reliability.
Top-Entry Bonnet Structure:Self-sealing connection between bonnet and body facilitates online maintenance of internal parts without removing the valve from the pipeline.
Extended Cooling Stem (Optional):Stem equipped with cooling section or extended design to reduce packing box temperature, protecting packing and actuators for ultra-high temperature service.
Fire-Safe Design:Compliant with API 6FA. Graphite packing and metal sealing structure maintain tightness in case of fire, preventing catastrophic leakage.
Blowout-Proof Stem:Top-entry blowout-proof stem design ensures operational safety under ultra-high pressure conditions.
