Stainless Steel Butterfly Valves
Stainless steel butterfly valves give compact, quarter-turn isolation and flow control in corrosive, hygienic and seawater service. A stainless disc and body resist attack where iron would corrode.
We supply wafer, lug and double-flanged butterfly valves with SS304 or SS316 discs and bodies, EPDM, PTFE or metal seats, and sanitary tri-clamp versions.

Frequently asked questions
What is a sanitary butterfly valve?
A butterfly valve with polished stainless surfaces and tri-clamp or weld ends that can be cleaned in place, used in food, dairy and pharma lines.
Which seat material should I choose?
EPDM for water and many food applications, silicone for high-temperature food service, PTFE for chemicals. Tell us the fluid and temperature and we'll confirm.
Can it be automated?
Yes. The ISO 5211 top flange takes pneumatic or electric actuators directly.
