Manual Turbo Butterfly Valve DN125 Price, Adjustable Flow Rate
Factors Affecting the Price of Manual Turbo Butterfly Valve DN125
Currently, the price of a Manual Turbo Butterfly Valve DN125 generally ranges from RMB 380 to RMB 1,200. The specific price is influenced by the following factors:
Valve Body Material: Cast iron costs approximately RMB 380-600, ductile iron (QT450) costs RMB 550-800, and stainless steel (304/316) costs RMB 900-1,200.The main Butterfly Valve product names of China Butterfly Valve Network include:Electric Speed Control Butterfly Valve,Fire Signal Butterfly Valve,High Temperature Butterfly Valve,Pneumatic High Vacuum Butterfly Valve,Sanitary Butterfly Valve,Three Eccentric Multi-level Metal Hard-sealed Wafer Butterfly Valve,Worm Gear Ventilation Butterfly Valve,Quick-installed Sanitary Butterfly Valve.
Seal Type: Rubber soft seal (EPDM/NBR) is lower in cost, suitable for water and mildly corrosive media; PTFE seal offers better temperature and corrosion resistance but is slightly more expensive.
Disc Material: Ordinary galvanized plate or stainless steel plate directly affects corrosion resistance and service life; stainless steel disc increases the price by 30%-50%.
Turbo Actuator Type: A manual turbo head with open/close limit indicator is standard. Some models are optionally equipped with an explosion-proof handwheel or locking device, which slightly increases the price.
How Adjustable Flow Rate Is Achieved
The manual turbo butterfly valve uses a worm gear transmission mechanism to drive the disc to rotate 0-90°. When the disc is at any angle between 0° (fully closed) and 90° (fully open), precise flow regulation can be achieved. The self-locking function of the turbo head keeps the disc stable at any opening without requiring continuous external force, making it particularly suitable for scenarios requiring frequent flow adjustment, such as cooling water circulation control or tank inlet regulation.
Purchasing Suggestions
It is recommended that users select the material and seal type based on the medium type (clean water, sewage, mild acids/alkalis), working pressure (PN10/PN16), and regulation accuracy requirements. When purchasing, confirm that the valve complies with GB/T 12238 standards, and provide detailed operating condition parameters to the supplier to obtain an accurate quotation. It is advisable to compare at least three manufacturers, considering both quality and after-sales service.
