Long-Distance Pipelines High-Pressure Scratch-Resistant Pneumatic Double Flange Butterfly Valve

Product Description

Product Description

This series of butterfly valve use concentric structure design, and their main structure consists of body, disc, seat, stem and transmission mechanism parts, which can also according to the physical and chemical properties of different medium, to choose the corresponding material which is corrosion resistance, light resistance, aging resistance, and can be widely applied in the drainage, petroleum, chemical, food, medicine, energy systems and other fluid on the pipeline as the adjusting and intercepting device.

Product features 

1. Seat type: replaceable hard back seat, replaceable soft seat without back, and non-replaceable vulcanized seat to body , which is convenient for field maintenance, and all of them adopt the design of full flow to avoid the jamming of impurities, and their sealing can be reliably achieved to two-way sealing.Customers can choose different types and materials of seats according to different service requirements.
2. The structure is simple and compact, and with a small operating torque, which can achieve a quick 90° open and close. The flow 
characteristics is excellent with the bidirectional use and low flow resistance.
3. It could be opened and closed for many times and used for a long life time.
4. The test leakage is zero with two-way sealing.
5.The flow characteristics tend to be straight and the regulation performance is good.
