Shoulong Valve
1 / 1
Minimizes turbulence and pressure drop, making it ideal for flow-sensitive applications.
Double Block and Bleed (DBB) design ensures superior safety and leak prevention.
Enhances stability and durability in high-pressure and low-temperature environments.
Guarantees reliable sealing and performance at temperatures as low as -196°C.
Available in A350 LF2, Inconel 625, Hastelloy C, and other materials to meet diverse industrial needs.
Each valve undergoes comprehensive in-house cryogenic testing to ensure consistent, reliable performance.
DBB technology means the valve features two independent seating surfaces that simultaneously seal against pressure from a single source, with a bleed port between them. This isolates pressure on both sides and allows safe venting of the cavity between seats.
These cryogenic valves are engineered to deliver reliable sealing and consistent performance at temperatures as low as -196°C, ensuring mechanical integrity under extreme cold conditions.
The valves are available in a range of high-performance materials including A350 LF2 for low-temperature carbon steel, Inconel 625 for corrosion resistance, and Hastelloy C for corrosive environments.
It features a flow passage smaller than the inner diameter, which minimizes turbulence, reduces pressure drop, and prevents fluid hammer, providing consistent flow control.
Each valve is subjected to in-house cryogenic testing simulating real conditions, including shell pressure tests, seat leakage tests, and performance evaluations to verify sealing integrity.
This design fixes the ball in place with mechanical support at both ends, providing structural strength, reduced seat wear, lower operating torque, and enhanced durability for high-pressure service.
