Lined Globe Valve DN50 Price, Specialized for Strongly Corrosive Media
1. Key Factors Affecting Price
Body and lining material is the primary pricing factor. The valve body is typically made of cast steel or cast iron, with F46 being the most common lining material, resistant to strong acids, strong alkalis, and organic solvents. If PFA lining is selected, it can withstand temperatures up to around 200°C, but at a significantly higher cost. Manufacturing process also matters: full-lining compression molding is superior to ordinary injection molding, requiring strict vacuum and bubble-free standards, which increases cost. Additionally, spark testing on each unit further affects the final quote.The main stop valve product names of China Stop Valve Network include:Flange Fluorine-lined Globe Valve,Flange Straight-through Low Temperature Globe Valve,Oxygen-specific Globe Valve,GB Bellows Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Vacuum Isolated Straight-through Globe Valve,Y-type Jacket Insulation Globe Valve,Liquefied Gas Globe Valve.
Actuation method creates large price differences. Manual lined globe valves are the most economical. Pneumatic or electric actuators for remote automatic control add the cost of the actuator and accessories. Connection standards and customization requirements such as ANSI/JIS flanges, extended necks, or oil-free degassing treatment will also raise the price.
2. Price Reference Range (DN50, Strongly Corrosive Service)
A manual lined globe valve (F46 lining, cast steel body) is approximately 110–110–210 USD per unit. A pneumatic lined globe valve (complete set) is about 300–300–520 USD. An electric lined globe valve (complete set) is roughly 410–410–680 USD. For imported brands or PFA lining, prices generally exceed $680 USD per unit. Please note that the above prices are reference only, excluding tax and freight. Bulk orders typically receive better pricing.
3. Purchasing Advice
Always verify certification. Request lining material reports and spark test reports. Be sure to clarify your operating conditions: provide detailed medium composition (e.g., concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid), working temperature, and pressure to avoid incorrect selection. Request shell strength and seat leakage hydrostatic testing on each valve. If possible, request a sample or small trial batch to confirm corrosion resistance before bulk purchasing.
