Pneumatic high-pressure control valves use compressed air as the driving force and receive control signals such as 4-20mA through a valve positioner to achieve continuous and precise automatic adjustment of medium flow, pressure, or process parameters under high-pressure conditions.
Our control valves are engineered with optimized flow paths and control trims to deliver accurate, repeatable control across a wide operating range.
Specialized designs are available for high pressure, high temperature, corrosive, abrasive, and high differential pressure applications.
We offer a wide selection of valve body and trim materials, carefully selected to match process media and service conditions.operation.
Pneumatic high-pressure control valves use compressed air as the driving force and receive control signals such as 4-20mA through a valve positioner to achieve continuous and precise automatic adjustment of medium flow, pressure, or process parameters under high-pressure conditions. These valves feature high pressure resistance, stable regulation, and safety and reliability, and are widely used in high-risk, high-pressure differential industrial process control systems.
Core Advantages
1. Strong Pressure Resistance
Uses forged steel or high-strength alloy valve body, suitable for ultra-high pressure conditions.
2. Stable Regulation Performance
Flow characteristics can be selected as equal percentage or linear, with high control accuracy.
3. High Safety
Pneumatic actuators are intrinsically explosion-proof, suitable for flammable and explosive environments.
4. Erosion and Cavitation Resistant Design
Multi-stage throttling and pressure reduction structure effectively extends service life.
5. Comprehensive Fail-Safe Protection
Configurable with air-to-open/air-to-close/air-failure-to-hold safety conditions.
