J-VALVES
Structural Features
High Platform Stem Design: The top of the stem features an elevated platform with a directly exposed ISO 5211 standard flange interface, allowing direct mounting of actuators without traditional brackets and couplings. This reduces overall height by 30%–40%, enhances rigidity, improves transmission accuracy, and eliminates errors and vibration caused by connection clearances.
Three-Way Ball Design: The ball is available with L-port or T-port flow passages to enable multiple flow combination controls. Flow direction can be quickly switched via 90° rotation, simplifying piping systems and reducing the number of valves required.
Flanged Connection: RF (Raised Face) flanged connection conforming to ASME B16.5, ensuring reliable installation, interchangeability, and easy integration with existing piping systems.
Full ANSI Standard Range: Covers pressure ratings from ANSI Class 150 to Class 600 (PN20 to PN100), meeting a wide range of low- to medium-high pressure operating conditions.
Fire-Safe Design: Complies with API 607. Metal-to-metal sealing serves as a fire-safe backup seal, maintaining sealing performance and preventing media leakage even in fire conditions.
Anti-Static Device: Built-in anti-static spring and steel ball effectively conduct static electricity between the ball, stem, and body, reducing fire and explosion risks and meeting requirements for hazardous areas.
Blowout-Proof Stem Design: The stem adopts a bottom-loaded blowout-proof structure with shaft shoulders and retaining rings, preventing stem ejection under abnormal internal pressure and ensuring operational safety.
Wide Material Selection: Body materials include WCB carbon steel, CF8/CF8M stainless steel, A105/F304/F316 forged steel, etc., adapting to various corrosive environments and temperature requirements.
Compact Integrated Design: The high platform integrates actuator mounting functions, reducing the number of components, failure points, and maintenance costs.

Shipbuilding & Offshore Engineering: Used for multi-line distribution and diversion control in ballast water systems, bilge water systems, and fuel oil systems.
Gas Distribution Systems: For pipeline distribution of industrial gases (nitrogen, oxygen, hydrogen, natural gas) and multi-line filling control at filling stations.
Water Treatment & Environmental Protection: Used for multi-line distribution and process switching in water supply & drainage, sewage treatment, and reclaimed water reuse systems.
General Industrial Use: Suitable for flow direction switching, distribution, converging, and mixing control of water, oil, gas, chemicals, and other media.
Advantages & Value
Compact High Platform Structure: ISO 5211 direct mounting design eliminates brackets and couplings, reducing height by 30%–40% and saving installation space, especially ideal for confined areas.
Easy Installation & Maintenance: The high platform simplifies actuator installation and removal, reduces components, and lowers installation and maintenance labor and costs.
Safe & Reliable: Spring-return models automatically return to a safe position upon air or power failure; fire-safe, anti-static, and blowout-proof designs ensure safe operation in hazardous conditions.
Precise Flow Control: Precise L-port / T-port design enables flow switching without cross-contamination, meeting strict process requirements.
Wide Applicability: A full selection of materials, seal types, pressure ratings, port configurations, and actuators covers a broad range of low‑to‑high temperature and low‑to‑high pressure conditions.
International Standard Compliance: Designed and manufactured strictly in accordance with API 608, ASME, ISO and other international standards, meeting global project procurement requirements. Complete material certifications (EN 10204 3.1/3.2), test reports, and NACE compliance certificates are available.
