2026 Price Reference for UPVC Plastic Globe Valve DN80
As of 2026, the market price of a UPVC plastic globe valve DN80 varies significantly based on material grade, connection type, seal material, and actuation method. Based on current market data, the price typically ranges from RMB 120 to RMB 780 per unit .
A standard UPVC globe valve with socket adhesive connection and manual handwheel operation is generally priced in the RMB 120 to RMB 250 range . This configuration is suitable for most general acid and alkali applications with moderate operating conditions.
For flanged connection models, prices increase to approximately RMB 280 to RMB 450 due to the additional flanges and bolts required . A branded UPVC flanged globe valve is listed at approximately RMB 780 per unit for DN80 size .
For CPVC (chlorinated polyvinyl chloride) models, which offer superior temperature and corrosion resistance, prices range from RMB 280 to RMB 450 . CPVC is recommended for applications with higher operating temperatures or more aggressive chemical media.
It is important to note that these are reference prices. The final transaction cost depends on several factors including the specific material grade, connection type, seal material, and order quantity.
Connection Type
Socket adhesive connection is the most economical and commonly used for plastic piping systems. Flanged connections add approximately 20% to 30% to the total cost due to the additional hardware required. Threaded connections are also available but are less common for DN80 size valves.
Actuation Type
Manual handwheel operation is the standard and most cost-effective configuration. Equipping with pneumatic or electric actuators for automation control will significantly increase the total price.
Why UPVC Excels in Acid and Alkali Pipelines
UPVC plastic globe valves offer several distinct advantages that make them a first-choice solution for corrosive media handling.
Superior corrosion resistance is the defining characteristic. UPVC material resists a wide range of acids, alkalis, and chemical solutions without the electrochemical corrosion that plagues metal valves. The material is inert to hydrochloric acid, sulfuric acid, nitric acid, and most caustic solutions.
Lightweight construction significantly reduces installation costs and support structure requirements. UPVC material weighs approximately one-fifth that of carbon steel, making handling and installation easier.
Smooth internal surface results in low flow resistance and prevents scaling, making it especially suitable for transporting acidic and alkaline wastewater containing suspended particles.
Hygienic and non-toxic properties make UPVC suitable for drinking water and food processing applications where material safety is critical.
Key Selection Parameters for Acid and Alkali Applications
When specifying a UPVC plastic globe valve DN80 for acid and alkali pipelines, several critical parameters must be carefully defined.
Operating Temperature – UPVC is suitable for 0°C to 50°C for continuous service, with a maximum of 70°C. For temperatures up to 95°C, CPVC should be specified. For extreme temperatures up to 140°C, PVDF is recommended.
Pressure Rating – Standard UPVC globe valves are typically rated for PN10 or PN16 (1.0 to 1.6 MPa). Confirm the valve's pressure rating exceeds your system's maximum operating pressure.
Media Compatibility – For strong acids and alkalis, verify the material compatibility with your specific chemical composition. PVDF or PTFE-lined options are recommended for the most aggressive media.
Connection Standards – Ensure the valve's connection type matches your piping system. Confirm compliance with GB/T 10002.2 standards and request material test reports from the supplier.
Purchasing Recommendations for Buyers
The UPVC plastic globe valve DN80 is a proven solution for acid and alkali resistant pipelines, offering excellent corrosion resistance, lightweight construction, and reliable flow control. As of 2026, prices range from approximately RMB 120 to RMB 780, with the final cost determined by material grade (UPVC, CPVC, or PVDF), seal type (EPDM or FPM), connection method (socket or flanged), and actuation type (manual, pneumatic, or electric).
When selecting this valve for corrosive media applications, pay careful attention to the operating temperature (UPVC suitable up to 70°C, CPVC up to 95°C), pressure rating (PN10/PN16), media compatibility, and connection standards. For the most competitive and accurate pricing, contact manufacturers directly with your complete technical specifications and request material certifications to guarantee product quality. Investing in a correctly specified UPVC plastic globe valve is an investment in the long-term reliability and safety of your acid and alkali handling systems.
