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 valve's anti-static device further enhances operational safety in high-risk environments.
The spring-loaded seat design and Double Piston Effect seat options offer superior sealing performance, providing leak-free operation even under varying pressure conditions, ensuring reliability in dynamic industrial processes.
Crafted from high-quality forged steel and corrosion-resistant materials, this valve is built to withstand harsh conditions, including exposure to chemicals, water treatment processes, and mild corrosive environments. It offers long-term durability and protection from wear and tear.
The valve supports manual, worm gear, electric, and pneumatic actuation. With ISO 5211 direct mounting options, it is designed for easy automation integration, reducing downtime and simplifying maintenance for long-term operational efficiency.
Available in Full Bore and Reduced Bore configurations to match the system's flow and pressure requirements. This versatility allows you to tailor the valve to your specific application needs, ensuring optimal performance.
The valve is available in a range of sizes and materials, including A694F52, A694F60, A694F65, A182F6A, A182F316, A182F347, and Inconel 625, allowing for customization based on specific industrial needs.
Double Block and Bleed (DBB) allows the valve to block flow from both upstream and downstream sides simultaneously while providing a bleed port to vent or drain the cavity between the two seats. This is critical for maintenance safety and isolation in high-pressure pipeline systems.
Yes. The valve is designed and tested to meet Fire-Safe standards including API 607 and ISO 10497. These certifications confirm that the valve maintains structural integrity and provides reliable sealing even under extreme heat.
This 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 integration.
The valve is offered in high-performance materials including A694F52, A694F60, A694F65, A182F6A (Martensitic stainless steel), A182F316 (Austenitic stainless steel), A182F347, and Inconel 625 for extreme corrosion resistance.
A Full Bore valve has an opening equal to the pipe's inner diameter for unrestricted flow and pigging. A Reduced Bore valve has a smaller flow path, which is often more cost-effective and suitable where space or weight is a concern.
This valve is engineered for demanding environments including Oil & Gas, Chemical & Petrochemical processing, Power Generation, Water Treatment, and general high-pressure industrial pipeline systems.
