Product description
Strong corrosion resistance: Made of engineering plastics such as PVC, CPVC, PP, PVDF, etc., suitable for corrosive media such as acid, alkali, salt, etc.
Lightweight: Only 1/4~1/3 of the weight of metal valves, easy to install.
No secondary pollution: meets the hygiene requirements of industries such as food and medicine (some materials have passed FDA certification).
Structure Design
Simple and compact: Butterfly plate rotating opening and closing, simple structure, small space occupation.
Low flow resistance design: When fully open, the flow channel is unobstructed and the pressure loss is small.
Reliable sealing: Using soft seals (such as EPDM, FPM rubber) or hard seals, the leakage level can reach ANSI Class VI.
Easy to operate
Flexible opening and closing: handle, worm gear, pneumatic or electric drive are optional, with low operating torque.
Visual indication: Some models are equipped with an opening indicator ruler for easy status monitoring.
Wide applicability
Temperature adaptation: Depending on the material, the temperature resistance range is -20 ºC~120 ºC (PVDF has better high temperature resistance).
Media compatibility: Suitable for water, gas, weakly corrosive liquids, and particulate media (wear-resistant materials should be selected).
Economical and durable
Low maintenance cost: no complex internal structure, low failure rate, easy to clean.
Long lifespan: resistant to aging, UV resistant (some materials add UV resistant agents), suitable for outdoor environments.
