Stainless steel lug type butterfly valve
Stainless steel lug butterfly valve, which can be driven by aluminum alloy handle or worm gear box, namely handle lug type butterfly valve, worm gear lug type butterfly valve; if customer needs, it can also be installed as electric actuator, pneumatic actuator, and become an automatic control electric actuator Lug Butterfly Valve, Pneumatic Lug Butterfly Valves. The structure is a centerline type, and the sealing structure is a soft seal – the optional valve seats are EPDM, PTFE, NBR, etc.; only need to rotate 90 degrees, it can be switched on and off, and the operation is simple. When the lug butterfly valve is fully opened, the only resistance to the flow of the medium through the thickness of the valve plate, so the pressure drop generated by the lug butterfly valve is very small, so it can be used as a valve to adjust the flow.
