Stainless Steel Wafer Type Butterfly Valve
A Stainless Steel Wafer Type Butterfly Valve is a compact, lightweight flow control device designed to fit between two flanges in a pipeline. Its wafer-style body ensures space-saving installation while maintaining a strong seal against bi-directional pressure. The valve uses a circular disc mounted on a rotating shaft to regulate or shut off fluid flow with a quarter-turn operation. Manufactured from high-grade stainless steels such as SS304, SS316, or SS316L, this valve provides excellent corrosion resistance, durability, and performance in aggressive media handling. It is widely used in chemical, water treatment, oil & gas, marine, food & beverage, and HVAC applications.
Key Features of Stainless Steel Wafer Type Butterfly Valve
- Wafer-Type Design: Compact body fits between flanges, reducing installation space.
- Quarter-Turn Operation: Provides quick and reliable shut-off or throttling.
- Robust Stainless Steel Construction: High strength and resistance to corrosion, scaling, and erosion.
- Tight Shut-Off: Available with resilient or metal seats for leakage-free performance.
- Lightweight & Easy Installation: Requires fewer bolts compared to lug or flanged types.
- Automation Ready: Can be equipped with pneumatic, electric, or hydraulic actuators.
- Versatile Service: Suitable for liquids, gases, and semi-solid media.
- Standards Compliant: Designed in accordance with API, ASME, and ISO norms.
