Application fields

Soft seated type Used as porable water,waste water,power plants,shipbuilding industry,checmical and petrochemical piper mill

Other remarks1

Compact structure, easy installation and disassembly, repair friendly and light weight

Other remarks2

It has a certain adjustment capability, and can be used as a control valve.

Other remarks3

With the triple-eccentric structural design, the sealing face is separated as soon as opening, so the mechanical wearing and friction between two sealing faces is eliminated during the opening and closing of butterfly plate, the operation torque is lowered, and the service life is longer.

Other remarks4

Good sealing performance of zero leakage.

Other remarks5

Wide range of application - triple-eccentric metallic sealing butterfly valves have a wide range of temperature, pressure and diameter.

Soft seated butterfly feathred with concentric design,is a reliable maintenance free and cost effective valve.with various optional elastomer material,it can ensure gas tight seal,leakage free and corrosion resistant in various applications.Seat is designed with backup rng prevents the seat from collapsing or dislodging and is easily replaceable in the field.Upon client request,this kind of valves can also be designed for DEAD END service at maximum pressure rating
