Stainless steel 3-way ball valve anti-corrosion, anti-penetration, anti-friction multi-layer seal, valve seat with soft and hard double seal, increase the stability of the seal, valve body material: carbon steel, stainless steel, working temperature: -46 ° C ~ +200 ° C

Stainless steel 3-way ball valve is a relatively new type of ball valve, it has its own unique structure of some advantages.Stainless steel three-way ball valve has the advantages of small fluid resistance, simple structure, small volume, light weight, compact and Reliable, convenient operation, quick opening and closing, convenient maintenance and so on. The following details of the stainless steel tee ball valve working principle and stainless steel tee ball valve advantages.

It works as follows:
A, the opening process
1 In the closed position, the ball is mechanically pressed by the valve stem and pressed against the valve seat.
2 When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and the bottom angular plane causes the ball to disengage from the valve seat.
3 The valve stem continues to lift and interacts with the guide pins in the spiral groove of the valve stem, causing the ball to start rotating without friction.
4 Until the fully open position, the stem is raised to the extreme position and the ball is rotated to the fully open position.
B, the closing process
1 When closing, turn the handwheel clockwise, the valve stem begins to lower and the ball moves away from the seat.
2 Continue to rotate the hand wheel. The valve stem is subjected to the guide pin embedded in the upper spiral groove, so that the valve stem and the ball rotate at 90° at the same time.
3 When it is about to close, the ball has rotated 90° without contact with the seat.
4 In the last few turns of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges against the ball, causing it to press tightly against the valve seat for a complete seal.
Five, stainless steel three-way ball valve structure features:

1. Open and close without friction. This function completely solves the problem that the conventional valve affects the sealing due to the friction between the sealing faces.
2. Top-loading structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the parking of the device and reduce the cost. This type of valve should generally be installed horizontally in the pipeline.
   3, single seat design. It eliminates the problem that the cavity medium in the valve affects the safety of use due to abnormal boosting.
3. Low torque design. The specially designed valve stem can be easily opened and closed with a small handle.
4. Wedge seal structure. The valve is mechanically supported by the valve stem, and the ball wedge is pressed onto the valve seat to seal, so that the sealing property of the valve is not affected by the change of the pressure difference of the pipeline, and the sealing performance is reliably guaranteed under various working conditions.
5. Self-cleaning structure of the sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through the spherical sealing surface at 360°, which not only eliminates the high-speed fluid scouring on the valve seat, but also washes away the accumulation on the sealing surface to achieve self-cleaning.
