Multi scenario applicability

Multi scenario applicability
01
Can adapt to different lining materials (such as nitrile rubber, ethylene propylene rubber) to meet special medium requirements;
02
Supports vertical, horizontal and other multi station installation, compatible with manual, pneumatic or electric control methods.

Flexible operation and quick response

Flexible operation and quick response
01
Driven by lightweight wheels or pneumatic actuators, opening and closing only require 90 ° rotation (action time ≤ 5 seconds), supporting frequent switch operations.

Low flow resistance and high regulation accuracy

Low flow resistance and high regulation accuracy
01
The flat butterfly plate structure reduces medium flow resistance and system pressure loss, especially suitable for high flow gas or liquid transportation;
02
The flow characteristics are close to a straight line, and the medium flow can be accurately controlled by 90 ° rotation, with better regulation performance than ordinary gate valves or globe valves.

Compact, lightweight, and easy to maintain

Compact, lightweight, and easy to maintain
01
The clamp type connection design has a small volume and light weight, suitable for narrow pipeline spaces, and does not require additional flanges during installation, saving costs;
02
The seal can be replaced independently, and there is no need to disassemble the valve body during maintenance, reducing downtime.

Bidirectional sealing and zero leakage

Bidirectional sealing and zero leakage
01
Adopting a bidirectional soft sealing structure, the valve seat and butterfly plate are sealed with fluoroplastic, achieving complete medium isolation when closed, and the leakage rate meets national standards;
02
Special elastic compensation design (such as a four stage sealing structure) can maintain stable sealing performance even under working conditions of -50 ℃~+200 ℃.

Excellent corrosion resistance

Excellent corrosion resistance
01
The valve body, butterfly plate and other overcurrent components are lined with fluoroplastics (such as polytetrafluoroethylene), which can resist corrosive media such as strong acids, alkalis, salt solutions and organic solvents, and are suitable for high corrosion scenarios in chemical and pharmaceutical industries.
