J-VALVES
Design Features
F51 Duplex Stainless Steel Material: The valve body is forged from ASTM A182 F51 (2205/S32205) with a PREN value ≥ 35, delivering excellent resistance to pitting corrosion, crevice corrosion and chloride-induced stress corrosion cracking, with approximately twice the strength of 316 stainless steel.
Full Forged Construction: The valve body is fully machined from forgings, free of casting defects, with dense grain structure, providing significantly higher pressure-bearing capacity and fatigue life than castings, especially suitable for high-pressure pulsating service conditions.
Floating Ball Design: The ball floats freely under medium pressure and tightly contacts the downstream seat to form self-energized sealing, featuring a simple structure, reliable sealing and sensitive response.
3/4×1/2 Reduced Bore Design: Nominal valve size 3/4 inch with a 1/2 inch bore (reduced bore), reducing weight,operating torque and cost while ensuring process flow capacity, ideal for high-pressure pipelines not requiring full-bore pigging.
Double Block & Bleed (DBB) Function: Equipped with two independent seats for bi-directional bubble-tight shutoff, with a bleed/drain valve in the valve body cavity, enabling on-line cavity pressure relief and seal integrity testing, meeting API 6D isolation requirements.
Threaded / Socket Weld / Buttweld End Connections: Optional NPT female threads, SW socket weld or BW buttweld ends, complying with ASME B16.11/B16.25 standards, ensuring high connection reliability at 600LB high-pressure class.
Fire-Safe Design: Compliant with API 607 standard; in case of PTFE/RPTFE seal burnout, a secondary metal seal is formed between the metal ball and seat ring to prevent medium leakage under fire conditions.
Anti-Static Device: Conductive springs installed between the stem, ball and valve body ensure continuous static dissipation, suitable for flammable and explosive media such as natural gas and oil-gas mixtures.
Blowout-Proof Stem Design: The stem is secured with a bottom shoulder to prevent ejection under abnormal internal pressure, ensuring personnel and equipment safety.
Emergency Seal Lubrication System: Optional sealant injection valves at the seat and stem areas to restore temporary sealing by injecting sealant in emergency situations.
Compact & Lightweight: Small-bore high-pressure design with compact dimensions and light weight, facilitating installation in confined spaces and integration into skid-mounted equipment, instrument tubing and high-pressure distribution systems.
