Stainless Steel Worm-Gear Butterfly Valve
Manual worm-gear operated butterfly valve with full stainless body and seat for harsh-environment service.
Inquire NowProduct Overview
The stainless steel worm-gear butterfly valve uses an all-CF8/CF8M body, disc, and stem for maximum corrosion resistance. The manual worm-gear operator with handwheel provides reliable mechanical advantage for easy open/close at high differential pressure.
An optional electric or pneumatic actuator can be mounted on the standard ISO 5211 platform for automation. The seat features EPDM or PTFE liner depending on fluid compatibility.
Key Features
- Full Stainless Steel: CF8 / CF8M body, disc, stem — fully corrosion-resistant
