Q41f Brass Ball Valve with Flange

First, Q41F-16T brass flanged ball valve introduction:
Brass flanged ball valve is evolved from the plug valve, its opening and closing part is a ball, the ball around the center line of the valve body for rotation 90 degrees to achieve the opening and closing of a valve. Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium. Ball valve is widely used in recent years a new type of valve, it has the following advantages: fluid resistance is small, its resistance coefficient is equal to the same length of pipe segment, simple structure, small volume, light weight; Tight and reliable, at present, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in vacuum systems; Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient, in the fully open or fully closed, the ball and the sealing surface of the seat and the medium isolation, the medium through, will not cause the erosion of the valve sealing surface; Wide range of application, diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.

Second, Q41F-16T brass flange ball valve main connection size and weight:

Installation precautions: (
1) Remove the protective cover on both sides of the flange end and rinse the valve when it is fully open. (
2) Before installation, the whole machine should be tested according to the specified signal (electric or pneumatic) (to prevent vibration from affecting the performance due to transportation), and the line can be installed after passing the test (wiring according to the electric actuator circuit diagram). (
3) Before preparing to connect with the pipeline, it is necessary to flush and remove the remaining impurities in the clean pipeline (these substances may damage the valve seat and ball). (
4) During installation, please do not use the actuator part of the valve as the lifting point to avoid damage to the actuator and accessories. (
5) This type of valve should be installed in the horizontal direction or vertical direction of the pipeline. (
6) The pipeline near the installation point should not be low or bear the phenomenon of external force, and the pipeline bracket or support can be used to eliminate the deviation of the pipeline. (
7) After connecting with the pipeline, please use the specified torque to cross-lock the flange connection bolt.
