- Key Products/Technologies
- Ball Valve: Designed and tested according to API 6D and ASME B16.34 standards, featuring a Double Block and Bleed sealing principle. It meets FIRE SAFE requirements (API 6FA and API 607) and incorporates a PMSS (Primary Metal Secondary Soft Seat) dual sealing structure with high hardness coating and low-friction rubber for leakage prevention and extended lifespan.Ball Valve: Designed and tested according to API 6D and ASME B16.34 standards, featuring a Double Block and Bleed sealing principle.

- Cryogenic Valve: Specialized valves for piping systems used in the storage and transport of liquefied gases such as LNG, liquid nitrogen, and oxygen. Key features include an extended bonnet and an enclosed vapor chamber to isolate packing from cryogenic fluids, ensuring proper function. It utilizes materials suitable for low temperatures and heat treatment technologies, including austenite stainless steel, Teflon or other plastic packing, and Stellite 6.Cryogenic Valve: Specialized valves for piping systems used in the storage and transport of liquefied gases such as LNG, liquid nitrogen, and oxygen.

- Pressure Seal Valve: Engineered for high-pressure and high-temperature applications, available in various types such as gate, globe, swing check, and tilting disc check valves. It offers efficient flow passage and sealing performance, characterized by significant weight savings and ease of installation and maintenance.Pressure Seal Valve: Engineered for high-pressure and high-temperature applications, available in various types such as gate, globe, swing check, and tilting disc check valves. It offers efficient flow passage and sealing performance, characterized by significant weight savings and ease of installation and maintenance.
- Bellows Seal Valve: Used for handling toxic or explosive media and in applications where flow regulation issues may arise. It replaces conventional stem packing with a flexible metallic membrane and welds all potential leakage paths to completely prevent dry escape of gas or fluid. The bellows units undergo life cycle testing to ASME B16.34 requirements, ensuring a Low Fugitive Emission valve with leakage less than 100 ppm of volatile organic compounds.Bellows Seal Valve: Used for handling toxic or explosive media and in applications where flow regulation issues may arise.

- Parallel Slide Gate Valve: Ideal for high-temperature and high-pressure lines to prevent thermal binding, especially in high differential pressure services or where thermal expansion might cause sticking of wedge-type valves. It features a parallel slide gate assembly comprising two interchangeable spring-loaded discs, a fully guided disc holder, and retaining pins.Parallel Slide Gate Valve: Ideal for high-temperature and high-pressure lines to prevent thermal binding, especially in high differential pressure services or where thermal expansion might cause sticking of wedge-type valves. It features a parallel slide gate assembly comprising two interchangeable spring-loaded discs, a fully guided disc holder, and retaining pins.
- Butterfly Valve (Triple Offset Type): Provides bi-directional and bubble-tight shutoff through a triple offset metal seat design. The triple offset geometry of the valve stem, seat surface centerline, and conical axis completely eliminates rubbing, resulting in excellent seat part durability and low operating torque.Butterfly Valve (Triple Offset Type): Provides bi-directional and bubble-tight shutoff through a triple offset metal seat design.
