YNTO Stainless Steel Valve Body Pneumatic Flanged Triple Offset Hard Sealing Butterfly Valve
Product Features
1. The unique three-offset design eliminates friction between sealing surfaces, extending the valve's service life.
2. Elastic sealing is generated by torque.
3. The ingenious wedge design provides an automatic sealing function that tightens as the valve closes, ensuring compensatory sealing with zero leakage between surfaces.
4. Compact size, lightweight, easy operation, and convenient installation.
5. Pneumatic and electric actuators can be configured according to user requirements to meet remote control and programmable control needs.
6. Replacement of component materials can be adapted for various media, and lining for corrosion protection is available.
Product Overview
The Pneumatic Flanged Hard Sealing Triple Offset Butterfly Valve (D673H/W) features a precision U-shaped elastic sealing ring and a multi-layer metal hard sealing structure with three offsets. Both the valve seat and the butterfly plate sealing surfaces are made of cast iron and stainless steel, providing excellent corrosion resistance. It is easy to operate, has good sealing performance, a long service life, and is easy to install. This valve is widely used in industrial pipelines for metallurgy, power, petroleum, chemical engineering, as well as water supply and drainage, and municipal construction, serving to regulate flow and interrupt fluid flow for media with temperatures ≤ 425°C.
