Van bướm Georg Fischer– Mã : 365

The Type 365 Butterfly Valve can be used universally as a shut-off or control valve in high purity water treatment or water filtration applications.

The manually-operated Type 365 PTFE-lined lug-style Butterfly Valve with PFA encapsulated disc includes key features such as ANSI 150 bolt patterns, pressure ratings up to 150 PSI and temperature ratings up to 400°F.

All valves have a one-piece disc and stem arrangement with a lock-in PFA encapsulation. All valves are cleaned and manufactured for Ultrapure water service.

Fields of Application:

• Ultrapure DI Water
• Hot Ultrapure DI Water

Advantages:

• ISO 5211 actuator mounting for gear operators and actuators
• Self-lubricating bearings in the upper and lower stem journals
• Precision-machined virgin PTFE liner is 100 mils minimum thickness
• Precision PFA encapsulation 100 mils thick, bonded and interlocked to the one-piece disc stem, provides maximum permeation protection and prevents delamination
• Belleville disc springs exert uniform loading through the pusher pressing the PTFE liner and the shoulder of the PFA encapsulated disc/stem together, resulting in a leak-free mechanical stem seal
