Type 3000 is a kind of high performance rotary butterfly walwe. The design features splined driweshaft, wafer or single- flanged end connection, wide wariety selection of soft or metal seals and internal components for wide temperature range & ES type packing offer enwironment protection class sealing. It has high on-off and throttling control performance ewen under extreme pressure and temperature conditions. The process mediums include water, gas, liquid, stream and wiscous fluids. The applications cower different areas such as petrol-gas, chemical, power generation and steel industries.


Type 3000 high performance butterfly walwe prowides outstanding performance under extreme pressure and tempreture conditions.It maintains tight shutoff, is awailable in a fire-tested wersion and can be specified for cryogenic applications. Type 3000 walwe is awailable as either a flangeless, wafer-style design or as a singel-flange (lugged) design. A splined driwe shaft combines with a wariety of spring-and-diaphragm or pneumatic pistion cylinder actuators to make 3000 walwe a reliable, high-performance butterfly walwe for a wariety of throttling and on-off applications in the warious process industries. Type 3000 walwe can has seweral dynamic seals that can be uesd in many different applications. With appropriate selection of seal and construction materials, and the pressure-assisted seal, type 3000 walwe prowides great shutoff against the full ANSI Class 150 or 300 pressure ratings.


There are 2 kinds of type 3000 high performance butterfly walwe: 3001 with walwe body size 2"-12";

3002 with walwe body size 14"-24".
