The high-performance butterfly valve series is developed to solve the high and low temperature, high pressure, vacuum and other working conditions that are difficult for general valves to adapt to. It has a unique self sealing and double eccentric structure, and through the selection of three sealing materials, it ensures high performance under a wide range of usage conditions. It can be applied to a wide range of fluids such as corrosive mud and high-temperature steam that cannot be sealed by ball or gate valves.
The use of PTFE sealing rings can be applied to highly corrosive chemicals and high-temperature fluids up to 275 ° C. Example: Pure water, air conditioning cold and warm water, seawater, water. Formalin solution. Organic solvents, air, oxygen, exhaust gas, urban gas, coking gas.
Good sealing performance, long working life, simple structure, lightweight material saving, convenient disassembly and assembly, easy to form remote control flow cutoff and throttling control. This series of valves is suitable for various pipelines with valve diameters ranging from DN40 to DN600, pressure ratings ranging from 150LB to 300LB, and PN6 to PN40.
Product features:
1. Small and lightweight, easy to disassemble and repair, and can be installed in any position
2. Simple and compact structure, low operating torque, and quick opening with 90 ° rotation
3. Flow characteristics tend to be straight, with good regulation performance
4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes possible internal leakage points
5. The outer circle of the butterfly plate adopts a spherical shape, which improves sealing performance and extends the service life of the valve. It maintains zero leakage even after opening and closing under pressure for more than 50000 times.
6. The sealing element can be replaced and the sealing is reliable, achieving bidirectional sealing
7. Butterfly plates can be sprayed with coatings according to user requirements, such as nylon or PTFE
