Q641F pneumatic floating ball valve
Pneumatic floating ball valve Q641f
advanced pneumatic floating ball valve seat, seat ball valve manufacturing experience for many years and design, to ensure that the valve sealing, low friction coefficient, small operation torque, a variety of the seat material, wide adaptation.Switch and correct handle: the flat head valve stem, and handle the connection is not dislocation, so as to ensure the switch state and the valve of handle indicates a speech.Locking device: to prevent wrong operation valve switch, lock hole in the valve fully open and close position, ensure that the valve is in the right place.Stem fly prevention structure: stem is bottoms type, prevent pressure, at the same time can be in after the fire, and the body form metal contact, to ensure that the valve stem seal. Applicable medium: water, gas, oil, natural gas and acid and alkali corrosive medium.
