Product Introduction:
D673H pneumatic wafer triple eccentric metal seated butterfly valve consists of triple offset wafer butterfly valve and pneumatic actuator.
Driven by compressed air, the disc rotates 0°~90° to realize quick shut-off or flow regulation.
With triple offset wedge metal hard seal structure, no friction between sealing surfaces during operation.
It provides bi-directional tight shutoff, excellent performance on high temperature resistance, high pressure resistance, abrasion resistance and fire safety.
Compact wafer design saves installation space.
Application Fields:
Thermal power plant, district heating steam pipeline, petrochemical industry, metallurgical flue gas pipeline, coal chemical, gas transportation, thermal oil heating system.
