Soft seal for clip type butterfly valve bee seat material using synthetic rubber, PTFE refined, sealed good performance
Simple structure, two-way seal, compact structure, lightweight, affordable price
Valve 90 degrees turn, open and close quickly, flexible operation
Soft seal type central structure, Central soft seal score, stem from the center of the butterfly plate, butterfly valve connection can be used in the form of clamp type, single clip lug type, flange type
According to different operating conditions, can provide anti-corrosion desulfurization special score, no pin to clip butterfly valve, prevent the media in the cone pin residue and corrosion cone pin, cause the valve leakage
