J-VALVES
Forged Steel Full Bore Fully Welded Trunnion Ball Valve with Gear Box
Main Features
Fully Welded Structure: The valve body adopts a fully welded process without bolt connections, enhancing the overall strength and sealing performance of the valve, and it is especially suitable for high-pressure and high-temperature working conditions.
Stem Design: The valve stem is supported by bearings, which reduces the operating torque and improves the stability and reliability of the valve.
Full-bore Design: The internal flow passage is unobstructed, allowing the medium to flow smoothly with low pressure loss, and it is suitable for pigging operations.
Gearbox Operation: Equipped with a gearbox, it has a small operating torque, operates smoothly and reliably, and is suitable for the operation of large-diameter valves.
Fire Safety Design: It complies with the API 607 fire safety standard and can maintain its sealing performance in extreme situations such as fires.
Anti-static Device: It has a built-in anti-static device to ensure electrical continuity among the valve stem, ball, and valve body, reducing the safety risks caused by static electricity.
Anti-blowout Valve Stem Design: The valve stem design includes a protective sleeve to prevent the valve stem from being blown out under high pressure.
Low Emission Design: It adopts low-emission packing, meeting environmental protection requirements.
Multiple Connection Methods: It provides various end connection methods such as flange connection and butt welding connection to meet different installation requirements.
Technical Specifications
Size Range: 1/2"~56" (DN15~DN1400)
Pressure Rating: 150LB~2500LB (PN20~PN420)
Applicable Temperature: -29℃~425℃
Applicable Medium: Water, gas, oil, corrosive chemicals, etc.
Materials:
Valve Body: A105 forged steel.
Seat: Soft seal (such as PTFE, PEEK) or metal seal.
Stem: A105 forged steel.
Design Standards: It complies with standards such as API 6D and ASME B16.34.
Connection Methods: Flange connection (ASME B16.5), butt welding connection (ASME B16.25).
Operation Mode: Gearbox operation.
Application Fields
Petroleum and Natural Gas Industry: Used for oil and gas transportation, wellhead isolation, pressure testing, etc., and it is especially suitable for occasions requiring high reliability and fire safety.
Chemical Industry: Used to handle highly reactive chemicals to ensure process safety.
Power Industry: Used for medium isolation in high-pressure systems, such as boilers and turbines.
Municipal Engineering: Used in water supply and drainage systems to ensure water quality safety and pipeline maintenance.
