High performance butterfly valve
Triple or Double Eccentric design could minimize the friction between the sealing face and thus extends the life span of valves greatly.
With the continuous development and improvement,"J" type RPTFE seat is used which has a feature of good elasticity and long service period. It could compensate the sealing area automatically either caused by the changing of pressure/temperature or the worn out because of long-term use. This type of seat could guarantee the reliable sealing performance with the force of medium.
Self-Lubricated bushing with ultra-low friction coefficient could lower the friction force between stem and bushing, resulting in an easy opening and closing operation.
Disc and stem is connected with each other by a"Tangential Pin"which increases the stem's strength and also ensures the connection reliability between.
Unique floating seat design could automatically adjust its position as per the direction of upstream pressure to achieve an ideal sealing ratio needed in fully closed position so that double directional sealing could be realized. This design also extends the service life of the valve and increases the possibility that valves could be serviced more than one million times'opening and closing.
Anti-blow out design ensures stem won't be blown out from the valve due to the connection failure between disc and stem. Standard ISO5211 top mounting pad guarantees its easy connection with all kinds of actuators including electric, pneumatic and manual operation.
ANSI/FCI70-2 specifies the leakage class and testing procedure for control valves; High performance butterfly valve could reach bubble tight as per MSS-SP61, which is more critical than Class VI sealing.
Easy maintenance, parts are interchangeable with the improvement of production process; any defects on disc or stem could be replaced on site, and only general tools are needed for an overall maintenance work.
For the whole series of High performance butterfly valve, various material choices are available as per different working condition.
