Product Overview

Coat metal seal butterfly valve is based on a multi-level three eccentric metal seal butterfly valve , according to user needs butterfly new product development . In addition to the three eccentric multi-level metal seal butterfly valve all the excellent performance , but also two-way pressure , one of the biggest advantages that can be achieved butterfly tops in field maintenance . With the choice of body material , the use of temperature from -29 ℃ ~ 550 ℃, due to its good flow characteristics , both close truncated media can arbitrarily adjust the flow of the medium.

Applications

Top entry seal butterfly valve suitable for medium temperature -29 ℃ -600 ℃, nominal pressure of 0.6 ~ 2.5MPa media is on the water , steam, oil , hot air, corrosion and other pipeline in order to achieve truncated fluid flow and regulate media the purpose of opening and closing mechanism is the best way of all kinds of pipe . Top entry seal butterfly valve control: Worm , electric , pneumatic, pipe grid

Product Features

1 . The new coat structure can not be solved in the field of traditional eccentric butterfly valve maintenance problems. According to the original multi-layered past three eccentric butterfly valves, seals damaged when needed shipped back to the manufacturer for repair or remember a butterfly scrapped. Tops butterfly removed from the pipeline do not just spend very little time together will be able to open the bonnet stem and disc together from the body cavity of the

Removed for repair or replacement of seals, valve cover seal and then covered with catchy , the valve can be achieved during the maintenance period can not affect the normal operation of the pipeline system that made ​​the valve repair

Reduce the loss of a benefit to a minimum ;

2 . With multi-level three eccentric metal seal butterfly valve all the excellent performance ;

3 . Reliable sealing function , up gas seal leak ;

4 . Disc streamlined design , with high intensity , flow area, small flow resistance, energy saving.

Tops butterfly works:

Top entry seal butterfly valve is mainly composed of body, bonnet , disc valve shaft , valve seals, disc seals, bushings, bottom , drives and other components. By rotating the valve handwheel driven worm gear rotates , the worm drive stem and disc , as opposed to the body in the range of 90 degrees to rotate freely in order to achieve tops butterfly on and off, thereby regulating the flow of media will realize and truncation the purpose of the fluid, the valve clockwise handwheel is turned off.

Standard hard seal butterfly valve
