Marine Class 300 Ball Valve
Marine Class 300 Ball Valve is a fixed ball valve, need to be operated at normal temperature working environment; Nominal diameter: DN50-DN200, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media; Marine Class 300 Ball Valve has carbon steel, stainless steel, bronze and other materials; generally with flange connection, can also be butt-welded connection.Marine Class 300 Ball Valve actuation methods are: manual, electric, pneumatic, etc.
Overview
Driving method：
Electric executive operation: through the motor drive reducer, and then drive the valve stem rotation, so that the ball rotates to open or close position, to achieve the control of the medium.
Pneumatic executive operation: the use of compressed air generated by the power, by controlling the size of the gas source pressure, drive the piston of the cylinder for linear or rotary movement, thus driving the ball valve open and close.
Liquid executive operation: through the liquid power to operate the ball valve opening and closing, its working principle is similar to the pneumatic actuator, also through the control of liquid pressure to realize the valve switch.
