Wafer high performance butterfly valve Introduction
2023-02-10

Wafer high performance butterfly valve manufacturer, factory, company and supplier in China. Wafer high performance butterfly valve provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases Wafer high performance butterfly valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.

Wafer high performance butterfly valve widely used in many applications such as Airport refueling, Hydrocarbon processing, HVAC, Air treatment, Chemical processing, Purified gas, Steam and vacuum services, Potable water, Powder and pulp processing, etc.Wafer design makes the valve convenient for connection between flanges and save length in pipe line.

Wafer high performance butterfly valve Feature:

One-piece stem design with ISO 5211 square drive
ISO 5211 direct mounting flange on the valve body
Easy-adjust gland packing accessible with actuator mounted in place
Belleville washers on the gland nut offer reliable primary sealing between shaft and packing
Retaining ring for both equably pressing on packing and stem blowout proof
Multiply rows of RPTFE chevron for soft seat valve and Graphite chevron for fire safe and metallic seat
Extended neck for pipe insulation
Self-energized seat resulting in longer life and reduced maintenance·Pin-less shaft to disc connection makes the valve convenient for parts replacement and reliable even under corrosion
Seat retainer supports the seat and allows for easy changeout
Double offset disc reducing the valve torque
Alloy harden disc surface for metal seat increases the sealing life time
Integral disc stop prevent disc from over travel
Soft seat, fire safe seat and metallic seat are replaceable each other
PTFE lined SS316 bearing support stem and increase service life
Thrust ring for anti-blowout and anti-static
