Q641F pneumatic fluorine lined ball valve


Q641F pneumatic fluorine lined ball valve

Q641FThe pneumatic fluorine-lined ball valve rotates around the axis perpendicular to the channel90 degreesthe valve,Q641FPneumatic fluorine lined ball valveIt is a rotary type high-performance regulating or switching valve, which accepts industrial automation control (DCS,PLCSystem) The input and output of the current signal or voltage signal from the instrument source.Q641FThe pneumatic fluorine-lined ball valve can realize the proportional adjustment or two-position switch control of the fluid medium in the process pipeline, so as to achieve the automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.

Q641F46Pneumatic fluorine lined ball valve working principle:

Q41F46-10CThe working principle of the series of fluorine-lined ball valves is to make the valve unblocked or blocked by rotating the valve valve. The valve valve and the inside of the valve body are all made of fluoroplastics. It has the advantages of light switch, small size, reliable sealing, simple structure, and convenient maintenance. Wide range of use and other advantages.

Main appearance and connection dimensions of Q641F pneumatic fluorine-lined ball valve

Q641FPneumatic fluorine-lined ball valve product structure features:

1, The fluid resistance is small, and it is the one with the smallest fluid resistance among all valves.byAC220V,AC380VorDC24Vsupply voltage as power, accepting (4-20mA,0-10mAor1-5VDC) current signal or voltage signal to control the operation.Rotate the ball with the torque of the quarter-turn output0~90oto achieve the opening and closing action or regulating action.

2It is an all-electronic pneumatic actuator with an electromechanical integration structure.Q641FPneumatic fluorine-lined ball valve has functions such as internal servo operation, opening signal position feedback, position indication, and manual operation. It has strong functions, reliable performance, and simple connection.Q641FPneumatic fluorine-lined ball valve changes the rotation angle of the ball core by inputting a current signal or a voltage signal (0-90Any angle), to achieve proportional adjustment action.

3, The channel of the ball core is flat and smooth, and it is not easy to deposit the medium, and the ball can be passed through the pipeline. Simple structure, light weight, good sealing performance. Q641FPneumatic fluorine-lined ball valves are especially suitable for occasions requiring zero leakage rate.

4effectively reducing the ball andsealing ringThe coefficient of friction between them reduces the operating torque. When the medium pressure is small,Q641FThe contact surface between the sealing ring and the ball of the pneumatic fluorine-lined ball valve is small, so it has a large sealing specific pressure to ensure reliable sealing. When the medium pressure is high,Q641FThe contact area between the sealing ring and the sphere of the pneumatic fluorine-lined ball valve also increases accordingly, so the sealing ring of the valve seat can withstand a large thrust of the medium without damage, ensuring reliable sealing.
