Product introduction and characteristics :
The butterfly valve should be used for open, close and regulating medium flow in pipeline of petroleum, chemical, food, medicine, metallurgy, ship, can also be used in a variety of corrosive medium, The following feature:
1. Excellent bidirectional sealing performance, Minimized operation torque.
2. Flow characteristics tend to be straight, good regulation performance.
3. Adopt groove connection, install quickly.
4. Simple and compact structure, compact and light, easy totransport, install and disassemble.
Features :
1. The valve body seal is designed to be spherical, so that the contact between the valve body and the valve plate is uniform.
2. Design Self-made Water Seal for Valve Shaft. Increased safety factor for axial seals.
3. A non-pin stem is an anti-exit structure, and a card spring U type card structure is used in the upper part of the stem to prevent the stem from loosening in addition to compensating for the installation error.
4. The side flange adopts the groove design to save time for construction.
