Specifications center line butterfly valve with Pneumatic control

The metarial of the body take use of

better die-casting aluminum

Pneumatic center line butterfly valve Technical Data 1)Norminal Diameter:DN25-DN300 2)General Design:JIS10k/CLASS 150 3)Mounting Pad:ISO 5211 4)Face to Face:ANSI B16.10 5)End Connection:AWWA C606 6)Inspection and Test: API598   Material of Construction Body:Alloy Aluminum Disc:Stainless Steel Shaft:Stainless Steel Bushing:PTFE O-ring:EPDM   Product Features    Anti-sweat Wafer Butterfly Valve a.The metarial of the body take use of better die-casting aluminum, it is very light,easy to install. b.The material of disc used stainless steel. "S"-shaped disc design, not only improves the strength and stiffness of the valve disc , also reduce the weight and flow resistance.For spherical sealing surface,it has strong sealing performance. C.Long stainless steel neck on the upper body , can block the heat of liquid to the valve operation without any heat treatment. Similarly, during the cold water delivery, it  can prevent dew condensation happen. also can achieve that dew condensation never happen between the actuator and valve control surface.
