Q641F pneumatic ball valve product overview:
Q641F pneumatic ball valve is a ( ball ) around the axis of rotation perpendicular to the channel90ºvalve, which is composed of a pneumatic actuator and O type valve structure. Q641F pneumatic valve regulating type of rotary type high performance control or switch valve, acceptance of industrial automation and control ( DCS, PLC ) instrument source current or voltage signal input and output. Q641F pneumatic ball valve switch type, can be used as a simple switch. Q641F pneumatic ball valve can be realized in the process of pipeline fluid medium proportion regulation or two switch control, so as to achieve the fluid medium to flow, pressure, temperature, liquid level and other parameters of the automatic control. Q641F pneumatic valve can also be cut off valve, open to close in just 5seconds of time.
Q641F pneumatic ball valve features:
1.Q641F pneumatic ball valve fluid resistance small, are all valve fluid resistance of a minimum. Compressed air powered, adjustable accept (4-20mA,0-10mA or 1-5VDC ) a current or voltage signal, can control the running. Switch type accept simple contact models implement switch. Q641F pneumatic ball valve with angle stroke output torque rotating the sphere0~90 º, to open and close action or regulation of action.
2.Q641F pneumatic ball valve core channel smooth, easily deposited dielectric, can carry out pipeline pigging. Simple structure, light weight, good sealing performance. Q641F pneumatic ball valve is especially suitable for the requirements of zero leakage rate.
3.Q641F pneumatic ball valve is effective to reduce the friction between the ball and the sealing ring coefficient, reduce operating torque. When the medium pressure is small, Q641F pneumatic ball valve sealing ring and ball contact surface is small, there was a larger than the sealing pressure, ensure a reliable seal, when the medium pressure is larger, Q641F pneumatic ball valve sealing ring and ball contact area is increased, the seat ring can bear relatively large medium thrust without damage, ensure reliable sealing.
