Product Description
The Butterfly Valve 307 is used for controlling and shutting off the flow of the working medium.
A characteristic feature of this valve is the presence of a polytetrafluoroethylene (PTFE) seal, which provides high resistance to chemically aggressive environments. The valve housing (body) has a disassemblable construction (anchoring of two housing parts with screws), which ensures convenience in operation and seal replacement, as well as increases product durability.
Design features of the model:
- High chemical resistance of the seal and disc to chemically aggressive environments
- Sealing class “A”
- Disassemblable housing (body)
