Product Description
Butterfly Valve – Model 307 is designed for regulating and shutting off the flow of working media.
A key feature of this valve is the use of a PTFE seal, which provides high resistance to chemically aggressive media. The valve body is of a split type (two body parts connected by bolts), which facilitates servicing and seal replacement, and extends the device’s service life.
Design features of the model:
- High chemical resistance of the seal and disc to chemically aggressive environments
- Leakage class “A”
- Split body design for easy maintenance and seal replacement
Sealing materials:
🔹 PTFE, FEP, PO, PFA
Valve bodies can be manufactured from various materials depending on the application:
🔹 Carbon steels
A216 WCB (1.0619, GP240GH)
Discs can be made of the following materials:
AISI 316 + PTFE / FEP / PO / PFA
AISI 304 + PTFE / FEP / PO / PFA
A216 WCB + PTFE / FEP / PO / PFA
