UPVC Plastic Globe Valve DN80 Price, Acid and Alkali Resistant Pipeline
Factors Affecting the Price of UPVC Plastic Globe Valve DN80
Currently, the price of a UPVC plastic globe valve DN80 generally ranges from RMB 120 to RMB 450. The specific price is influenced by the following factors:
Valve Body Material: Standard UPVC (polyvinyl chloride) costs approximately RMB 120-250; CPVC (chlorinated polyvinyl chloride) offers better temperature and corrosion resistance, costing RMB 280-450.The main stop valve product names of China Stop Valve Network include:ANSI Flange Straight-through Bellows Globe Valve,Flange Straight-through Low Temperature Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Oxygen-specific Globe Valve,Vacuum Isolated Straight-through Globe Valve,Y-type Jacket Insulation Globe Valve,GB Bellows Globe Valve,Flange Fluorine-lined Globe Valve.
Seal Type: Conventional EPDM or FPM (fluoro rubber) seal rings. FPM performs better against strong acids and strong alkalis and is slightly more expensive.
Connection Method: Socket adhesive connection is the lowest in price; flange connection adds the cost of flanges and bolts, increasing the total by approximately 20%-30%.
Actuation Method: Manual (handwheel) is standard. Equipping with pneumatic or electric actuators for automation control will significantly increase the total price.
Advantages for Acid and Alkali Resistant Pipelines
UPVC material itself has excellent corrosion resistance to hydrochloric acid, sulfuric acid (concentration ≤70%), nitric acid (concentration ≤50%), and most alkalis, and does not suffer from electrochemical corrosion. The smooth inner wall of the valve results in low flow resistance and is not prone to scaling, making it especially suitable for transporting acidic and alkaline wastewater containing particles. Additionally, the weight of UPVC material is only one-fifth that of carbon steel, making installation and maintenance extremely convenient.
Purchasing Suggestions
It is recommended that users select the appropriate material based on the specific composition of the medium, operating temperature (UPVC suitable for 0-50°C, CPVC suitable for 0-80°C), and pressure rating (PN10/PN16). When purchasing, confirm that the valve complies with GB/T 10002.2 standards and request material test reports from the supplier. It is advisable to request quotes from at least three professional plastic valve manufacturers, comparing seal ring materials and after-sales service.
