Split-body PTFE butterfly valves are appropriate for a broad range of general applications*, including:

Pharmaceutical industry.
Adhesives, paper industry, dissolver.
Paint manufacture and processing.
Food industry.

Unitech split-body PTFE lined butterfly valves


Unitech’s split-body PTFE lined butterfly valves are designed to allow ease of maintenance and their one-piece disc/stem arrangement ensures zero movement between the disc and stem. These types of valves are suited for a wide range of applications and industries. BM Engineering Supplies stocks accompanying PTFE or 316 SS discs. 

These valves offer the following features and benefits:

Full PTFE liner allows for high temperatures (up to 180°C), chemically toxic and corrosive media.
Silicone resilient elastomer backup pad extends around the seat, including the disc hub. This provides uniform force sufficient for bubble-tight shut off.
Self-lubricating bearings are SS with PTFE coating.
Top and bottom secondary o-ring sealing prevents leaks to atmosphere.
