Industrial Valves for Extreme Environments
Complete Pipeline Flow Control Solutions
Reliable Industrial Valves for Critical Pipeline Systems
Industrial valves are the core components responsible for flow isolation, pressure control, and operational safety in modern pipeline infrastructure. In industries such as Oil & Gas, Petrochemical, LNG, Power Generation, and Industrial Processing, valve reliability directly impacts production efficiency and plant safety.
At Shaanxi Gold-Stone, we manufacture and supply a complete range of industrial valves engineered for severe-service conditions. All valves are produced according to internationally recognized API, ASME, and ASTM standards, ensuring long-term durability, leak-free sealing, corrosion resistance, and dependable performance under high pressure and extreme temperatures.
🛠 Industrial Valve Product Range
1. High-Performance Ball Valves
Floating Ball & Trunnion Mounted Designs
Our industrial ball valves are designed for rapid quarter-turn shut-off and reliable pipeline isolation.
Floating Ball Valve
The floating ball structure uses line pressure to press the ball against the downstream seat, delivering dependable sealing performance in medium-pressure systems.
Trunnion Mounted Ball Valve
The trunnion-supported design reduces operating torque and seat wear, making it ideal for high-pressure and large-diameter pipelines.
Features
- Low operating torque
- Bubble-tight sealing
- Fire-safe construction available
- Anti-static and anti-blowout stem design
- Suitable for automated operation
Applications
- Oil & gas transmission pipelines
- LNG facilities
- Petrochemical processing
- Water treatment systems
- Offshore platforms
2. Heavy-Duty Gate Valves
Gate valves are engineered for full-port flow and minimal pressure drop, making them ideal for on/off isolation services.
Features
- Straight-through flow path
- Low fluid resistance
- Bidirectional sealing
- Suitable for high-temperature service
- Available in bolted bonnet and pressure seal bonnet designs
Applications
- Crude oil transportation
- Refinery process systems
- Steam pipelines
- High-pressure utility lines
3. Check Valves (Non-Return Valves)
Check valves automatically prevent reverse flow and protect pumps, compressors, and process equipment from water hammer and pressure surges.
Features
- Automatic non-return protection
- Reduced pressure shock
- Low maintenance operation
- Swing, lift, and dual-plate designs available
Applications
- Pump discharge systems
- Boiler feedwater lines
- Hydrocarbon processing
- Chemical transfer systems

- Chemical process plants
- High-temperature utility piping
- Steam regulation systems
5. Flanged Ball Valves
Flanged ball valves are manufactured according to ASME face-to-face standards for easy installation and maintenance.
Features
- Robust flanged end connections
- Easy inline servicing
- Excellent structural rigidity
- High-pressure sealing capability
Applications
- Pipeline manifolds
- LNG terminals
- Industrial cooling systems
- Power generation facilities
6. Severe-Service High-Pressure Valves
Designed specifically for HPHT (High-Pressure High-Temperature) applications, these valves maintain structural integrity under extreme operating conditions.
Features
- Extreme pressure resistance
- High-temperature metallurgy
- Enhanced corrosion protection
- Long operational lifespan
Applications
- Supercritical power plants
- Deepwater offshore systems
- Petrochemical cracking units
- High-pressure process piping
