Product details

Pneumatic Valve Actuator

It is a kind of valve which rotates 90 °perpendicular to the channel axis. It consists of pneumatic actuator and O-valve structure. 

A rotating type of high-performance regulating or switching valves, which accept the input and output of current or voltage signals from industrial automation control (DCS, PLC system) instruments. 

The switch type, which can make a simple switch action, 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 rate, pressure, temperature, liquid level and other parameters of the fluid medium. 

Product characteristics

Pneumatic valve fluid resistance is small, is all kinds of valve fluid resistance is the smallest one. 

Using compressed air as the power, the regulating type can control the operation by receiving the current signal or voltage signal (4-20mA, 0-10mA or 1-5VDC). 

The switch type accepts the simple contact model to perform the switch action. 

Rotate the sphere 0 to 90 °with the torque output of the angular stroke to achieve the opening and closing action or adjusting action.

The ball core channel is smooth, not easy to deposit the medium, can carry on the pipe line type pass ball. 

The utility model has the advantages of simple structure, light weight and good sealing performance. 

It is especially suitable for situations where zero leakage rate is required.

The friction coefficient between the ball and the sealing ring is effectively reduced and the operating torque is reduced. 

When the medium pressure is small, the contact surface between the sealing ring of Q641F pneumatic ball valve and the sphere is smaller, so there is a larger sealing specific pressure to ensure reliable sealing. When the medium pressure is larger, the contact area between Q641F pneumatic ball valve sealing ring and sphere increases accordingly. 

Therefore, the valve seat seal ring can withstand greater medium thrust without damage, ensuring reliable sealing.
