PTFE Lined Butterfly Valves
4Matic PTFE lined valves are well suited for consistent performance requirements in highly corrosive applications involving chlorine, benzene, sulphuric acid, nitric acid, phosphoric acid, hydrochloric acid and sea water. Virgin grade resins and thick fluoropolymer linings provide for superior resistance to corrosive chemical effects, absorption and swelling.

High Performance Butterfly Valve
High performance butterfly valves are a type of rotary valve that uses a rotating disk to control flow through a pipe. The disk is generally operable through 90 degrees and provides a linear flow characteristic. For throttling control applications, one type of butterfly valve is now the industry standard: high-performance butterfly valves or double offset valves. Their advantages include a straight-through flow path, very high capacity, and the ability to pass solids and viscous media. High performance butterfly valve (also known as a double offset butterfly valve) features an innovative design that offers rugged reliability and extremely easy maintenance in the field. Independent and internal tests prove the valve’s superior service life capability with zero leakage shutoff.
