Product

Product Introduction:
High performance butterfly valve commonly used in gas and vacuum industries with high switching frequencies, the service life can reach millions of times. Even if the valve seat is damaged, it can be replaced on site by simply removing the insert, without disassembling the valve stem, valve plate and other parts.

High performance butterfly valves are widely used in power, petrochemical, coal chemical, metallurgy, hydraulic, papermaking, printing and dyeing, light industry and other fields. Also be used for cryogenic, vapor, chlorine gas, oxygen, high vacuum, corrosion and other special conditions.

Integral structure of the valve

Product Features

◆Fire- proof structure
Fire-proof valve is tested to API 607 4th Edition and BS 6755 Part Ⅱ
◆Fixed axis
Fixed collar is installed in the top of axis, 2"-24"(DN50- 600). when axis breaks accident, avoid the upper part to move out of gland.
◆Convenient to maintain and upkeep valve seats
Replace axis only by taking inserts down, without disassembling disc and axis.
◆Excellent for both On-Off and Control Application
The design of the sealing ring of the high-performance butterfly valve (PTFE soft seal adopts "lip-tooth" self-sealing structure, and hard seal adopts "U" shaped elastic seal) increases the service life of the valve, and the valve can be opened and closed repeatedly up to millions of times.
◆Bidirectional sealing, zero leakage
