■ Summarize
As secure safeguard, this series valve is used in coal gas residual heat power generation system and extraction steam turbine system. It can instead of electric cut-off butterfly valve and check butterfly valve because of its small flow resistance, super seal function.
■ Characteristic
1． It only needs 0.5 seconds to shut-off the valve rapidly and credibly.
2． Three-eccentricity metal seal structure open and close handily and don’t exist leakage.
3． Normal temperature medium can choose double-eccentricity soft seal structure which price is low and the seal performance is credible.
4． Shut-off valve swift by using spring or accumulator. All of two types are safely and credibly.
