Lug Type Lining Butterfly Valve
This lugged style butterfly valve has a robust design with many unique features developed from many years of manufacturing experience. Typically supplied with a carbon steel body with PTFE seat liner, with the disc being WCB encapsulated in PTFE or PFA. With all wetted parts PTFE / PFA the valve can be used in highly corrosive applications and is ideally suit to our lined piping systems. The valve can also be supplied with stainless steel body for clean room applications or for use in highly corrosive environments. The disc can be supplied in unlined stainless steel, titanium alloys and with TFM or PFA liners.

The valve has 3 separate stem seals preventing any fugitive emissions. The PTFE body liner is machined from a single PTFE billet to maintain total integrity. Behind the PTFE liner a Silicon or Viton energiser acts on the PTFE body live loading the body seal against the PFA/PTFE disc to give positive bubble tight shut off.
1. Design in split Type body, the parts of the valve can be disassembled, material-specific recycling possible
2. Maintenance-free, the valve can be installed in any desired position
3. ISO 5211 mounting pad for easy and quick actuator installation
4. Positioning holes keep valve in the center between pipe flanges and also applied to many international standards.
5. Three different sealings ensure the lined butterfly valve in high performance.
6. Three self-lubricating sleeves could keep stem not be deformed under pressing.
7. When the four Belleville Spring under pressing, it will make sealing among the gland, the seat and the disc edge more tightness
8. Epoxy coating with baked finishing before valve assembly, keep inner body can’t be rust.
