Product Description

Product Description
Ductile Cast Iron Di Ci Stainless Steel Barss EPDM Seat Water Resilient Wafer Lug Lugged Type Double Flange Industrial Butterfly Valve Gate Swing Check Valves
Application and Features
The expansion valve is suitable for applications in food, pharmaceuticals, chemicals, petroleum, power, textiles, papermaking, and other industries, where it serves to regulate flow and shut off media in pipelines for water supply, drainage, and gas pipelines with a temperature ≤ 425°C and nominal pressure ≤ 1.6MPa. It also has the function of compensating for pipeline contraction and expansion due to temperature changes.


 Features
  1. The design is innovative, reasonable, with a unique structure, lightweight, easy to operate, and quick to open and close.
  2. In addition to regulating flow and shutting off media, the expansion butterfly valve compensates for thermal expansion and contraction caused by temperature differences in pipelines, while also providing convenience for valve installation, replacement, and maintenance.
  3. The sealing components are adjustable and replaceable, ensuring reliable sealing performance.
