Butterfly valve product features

 


With pinless shaft connection, the transmission and two-way reliable sealing are enhanced, allowing the valve plate to be freely centered to the left and right, reducing the torque of the valve opening and closing and completely isolating the medium, eliminating internal penetration and corrosion opportunities.

Lubricating PTFE bushing

It adopts indoor and outdoor ring-shaped resin powder spraying, and the surface treatment technology of castings is advanced, the appearance of spraying is exquisite, and the anti-corrosion performance is better.

EPDM O-ring seal, this position and the O-ring of the valve seat form a two-way insurance, effectively preventing the medium from leaking.

The length of the valve body structure conforms to the ISO5752-1988 standard, and the universal interchangeability is strong.


The metal retains the connecting rod to prevent the valve from being horizontally installed or inverted to prevent the lower shaft from falling out during operation.
The single integral pin-free lower valve shaft is automatically centered with the upper shaft, avoiding seal leakage caused by the symmetry error of the disc.
The standard top flange hole is ISO5211 compliant and is suitable for mounting drives such as handles, worm gears, motorized heads and pneumatic heads.

 

 

Casting valve body
CI/HT200/GG20 Gray Cast Iron (PN10/16)
DI/QT450/GGG40 ductile iron (PN10/16)
WCB/CS precision cast steel (PN10/16)
SS stainless steel casting, 304SS, 316SS, 316L SS

 

 

Round washer, split ring and circlip combination effectively prevent the upper valve shaft from exiting. The valve shaft is easy to disassemble or replace, and the operation is simple, saving time and labor.

The rubber sealing ring adopts EPDM, which has good finish and strong flexibility. It enhances the sealing of the valve plate and the valve seat. It has a wide range of use and is easy to replace, which prolongs the service life of the valve seat.

The valve plate is made of SS304 stainless steel, which is a versatile stainless steel material with excellent rust resistance. High temperature resistance is also good, the general use temperature limit is less than 650 °C. 304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, nitric acid below the boiling temperature of 65%, 304 stainless steel has strong corrosion resistance. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. There are also a variety of materials to choose from: QT450 plating, QT450 nylon coating, SS316 stainless steel, SS316L stainless steel, double stainless steel and so on.

The flange connection hole conforms to the ISO5211 standard.
