2026 Price Reference for Pneumatic Globe Valve DN50
Pricing for a DN50 pneumatic globe valve varies widely based on body material, seal type, and actuator configuration. A general market reference places the range at approximately RMB 1,600 to RMB 4,800 for standard configurations. Within this range, a cast steel (WCB) body with a basic double-acting actuator typically costs around RMB 1,600 to RMB 2,600, while stainless steel bodies and single-acting spring-return actuators push the price higher. Some domestic suppliers list entry-level models at lower figures, though these may reflect simpler specifications or promotional reference prices.
Key Factors Influencing Price and Selection
Body and Trim Material – Cast steel WCB is the economical choice for water, oil, and steam. Stainless steel (304/316) is specified for corrosive media or hygiene-sensitive applications. Hardfacing with Stellite on the disc and seat enhances erosion resistance for high-temperature or abrasive service.
Seal Type – PTFE soft seals provide bubble-tight shutoff for clean media. Metal-to-metal hard seals are required for higher temperatures and steam service, where elastomers would degrade.
Actuator Configuration – Double-acting actuators require air pressure for both opening and closing and are the most economical option. Single-acting spring-return actuators provide fail-safe operation on air loss but add 30% to 50% to the cost. Adding solenoid valves, limit switches, or a positioner for modulating control increases the total package price by 40% to 80%.
Control Mode – Standard on-off control suits isolation duties. Modulating control with a 4-20mA positioner is available for flow regulation, though globe valves are generally recommended for fully open or fully closed service rather than continuous throttling.
Summary
The pneumatic globe valve DN50 delivers reliable automated flow control for industrial systems. Reference prices range from approximately RMB 1,600 for a basic cast steel configuration to over RMB 4,000 for stainless steel bodies with spring-return actuators and accessories. When specifying this valve, confirm the body material, seal compatibility with the process media, actuator fail-safe requirements, and control signal compatibility with your automation system.
