Shoulong Valve
1 / 5
Double Block and Bleed (DBB), Anti-Blowout Stem, and Fire-Safe Design (API 607 / ISO 10497) provide maximum safety, ensuring leak-free performance in critical process lines.
The spring-loaded seat design and Double Piston Effect seat options offer superior sealing performance, providing leak-free operation even under varying pressure conditions.
Crafted from high-quality forged steel and corrosion-resistant materials, this valve is built to withstand harsh conditions, including chemicals and water treatment processes.
Supports manual, worm gear, electric, and pneumatic actuation. With ISO 5211 direct mounting, it is designed for easy automation integration.
Available in Full Bore and Reduced Bore configurations to match system flow and pressure requirements, allowing customization for specific applications.
Available in a range of sizes and materials including A694F52, A694F60, A182F316, and Inconel 625 to meet specific industrial environmental conditions.
Double Block and Bleed (DBB) refers to a valve configuration that provides two seating surfaces that seal in the same direction, with a bleed port between them. This design ensures that any leakage past the upstream seat is safely vented, making it critical for high-risk process lines.
Yes. The valve is designed in accordance with API 607 and ISO 10497 fire-safe standards. This ensures that even in the event of a fire, the valve maintains its integrity and prevents hazardous leakage.
The valve supports multiple actuation methods including manual handwheel, worm gear, electric actuator, and pneumatic actuator. It also features ISO 5211 direct mounting pads for easy automation.
The valve is available in materials including A694F52, A694F60, A694F65, A182F6A, A182F316, A182F347, and Inconel 625 to suit different industrial corrosion requirements.
A Full Bore valve has an internal diameter equal to the pipeline for unrestricted flow, while a Reduced Bore valve has a smaller internal diameter, making it more compact and cost-effective for general flow control.
This valve is engineered for demanding industries including Oil & Gas, Chemical & Petrochemical, Power Generation, Water Treatment, and general high-pressure industrial applications.
