Q647F fixed pneumatic ball valve

Fixed pneumatic ball valve (two-stage)	Fixed pneumatic ball valve (three-stage)

1、 Overview of Fixed Pneumatic Ball Valve Products

The Q647F fixed pneumatic ball valve produced by Shanghai Yuhu Company is a new generation of high-performance pneumatic ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in the design. The fixed pneumatic ball valve is suitable for various corrosive and non corrosive media. Compared with floating ball valves, the Q647F fixed pneumatic ball valve transfers all the force generated by the fluid pressure in front of the valve on the ball to the bearing during operation, without causing the ball to move towards the valve seat. Therefore, the valve seat deformation is small, the sealing performance is stable, and the service life is long. It is suitable for high-pressure and large-diameter applications. Advanced spring pre seat components with self tightening characteristics achieve upstream sealing. Each valve has two valve seats, which can seal in each direction, so there is no flow restriction during installation, and it is bi-directional. This valve has two types of valve body structures: two-piece and three piece. The middle flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring. The rear of the steel ring is equipped with a spring to ensure that the valve seat is tightly attached to the ball, maintaining a seal. Both the upper and lower valve stems are equipped with PTFE bearings to reduce friction and make operation effortless. There are no adjustment plates at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. The fixed pneumatic ball valve adopts a full bore structure to ensure that the valve flow hole is consistent with the inner diameter of the pipeline for pipeline cleaning. Paired with an electrical valve positioner, it can control operation by inputting a 4-20mADC signal and a 0.4-0.7MPa gas source, achieving adjustments to parameters such as pressure, flow rate, temperature, and liquid level.

2、 Fixed pneumatic ball valve product features

(1) The fixed pneumatic ball valve adopts a fixed ball design, and the relative moving parts are made of self-lubricating materials with extremely low friction coefficient, resulting in low operating torque. In addition, the long-term sealing of the sealing grease makes the operation more flexible.
(2) The fixed pneumatic ball valve adopts a full bore or reduced diameter design, with low flow resistance.
(3) The fixed pneumatic ball valve adopts a fixed ball design and adds a pre tension spring, making the ball valve have automatic pressure relief function.
(4) Each ball valve has two movable sealing seats that can seal in both directions, so there is no need to consider the flow direction of the medium during installation.
(5) Featuring a fire-resistant and anti-static structure, conductive springs are installed between the valve stem and valve body, as well as between the valve stem and ball body, to prevent static electricity from igniting flammable media. Ensure system security.
(6) The fire-resistant structure provides dual protection. In the event of a fire that burns the sealing ring, all sealing parts of the ball valve can form a metal to metal hard sealing structure.
