Butterly valve feature
1.Unique wave line rubber seat, makes the concentric butterfly valve work similar to eccentric butterfly valve, reduces the friction between disc and rubber

2.Unique groove inside rubber back, reduces the torque of valve 20% to 30%, enhances the flexibility and life time of the seat more.

3.V- type ring around stem, prevent any leakage possibility

4.Stainless steel plate, ensures whole life proof of stem blow-out

5.Disc with two-piece shaft construction, enhance the flow capacity of the valve, The shape of the disc provides lower torque and prolongs the life span of the valve.
