Bi-Directional Soft Seal Butterfly Valve Features

Reliable bi-directional sealing with excellent leak-tightness.
No leakage under both positive and negative pressure conditions.
Sealing materials combine stainless steel and rubber for extended service life.
Half-shaft design for the valve stem enhances durability.
Truss-type butterfly disc offers a large flow area, low flow resistance, and energy-efficient operation.
Robust shaft sealing ensures long-term tightness.
Fully enclosed worm gear drive is corrosion-resistant, suitable for prolonged water applications.

Butterfly valves installed horizontally underground in pipe networks include a unique synchronous position indicator, allowing clear observation of valve status from multiple operation directions.
