Pneumatic Wafer Butterfly Valve DN80 Price, Automation Control System
Factors Affecting the Price of Pneumatic Wafer Butterfly Valve DN80
Currently, the price of a Pneumatic Wafer Butterfly Valve DN80 generally ranges from RMB 800 to RMB 2,500. The specific price is influenced by the following factors:
Valve Body Material: Cast iron body costs approximately RMB 800-1,200, while stainless steel (304/316) costs RMB 1,500-2,500.The main Butterfly Valve product names of China Butterfly Valve Network include:Pneumatic Soft-sealed Wafer Butterfly Valve,Electric Metal Hard-sealed Wafer Butterfly Valve,Fire Signal Butterfly Valve,Flange Soft-sealed Butterfly Valve,High Temperature Butterfly Valve,Pneumatic Desulfurization Wafer Butterfly Valve,Three Eccentric Multi-level Metal Hard-sealed Wafer Butterfly Valve,Sanitary Butterfly Valve.
Seal Type: Rubber soft seal is lower in cost, while PTFE (polytetrafluoroethylene) seal offers better corrosion resistance but is more expensive.
Actuator Configuration: Spring-return (single-acting) type is more expensive than double-acting type; explosion-proof actuators add extra cost.
Brand and Accessories: Imported brands or the addition of solenoid valves, limit switches, and positioners can increase the total price by 30%-50%.
Automation Control System Integration
Automation control of the Pneumatic Wafer Butterfly Valve DN80 is typically achieved using a PLC or DCS system. Through a 4-20mA signal, the system controls a solenoid valve or electric positioner to achieve precise valve opening adjustment. An integrated design can incorporate pressure and flow sensors to achieve closed-loop control, improving production efficiency and safety.
Purchasing Suggestions
It is recommended that users consider the medium characteristics, working pressure (typically PN10-PN16), and control accuracy requirements, and comprehensively evaluate the valve body material and control accessories. When purchasing, ensure to confirm the interface standard (ISO 5211) and air supply pressure requirements.
For an accurate price quote, it is advisable to provide detailed operating condition parameters and request quotes from at least three professional suppliers for comparison.
