George Fischer Butterfl y Valve Type 365
Manually operated PTFE lined lug style butterfl y valve with PFA encapsulated disc. Valves have ANSI 150 bolt patterns and are
rated for pressures up to 150 psi and temperatures 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. Valves are available with
lever and gear operators as well as pneumatic or electric actuators.
• 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 prevent delamination.
• Belville disc springs exert uniform
loading through the pusher pressing
the PTFE liner and the shoulder of
the PFA encapsulated disc/stem
together, resulting in leak-free
mechanical stem seal.
