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 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.

• 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.
