Insulating Ball Valve Product Overview:
Insulated ball valves and flangesGate ValveA valve of the same type, distinguished by its spherical closure piece, which rotates around the centerline of the valve body to achieve opening and closing. Ball valves are primarily used in pipelines for...Distribution and alteration of the medium flow direction. Two-piece ball valveThree-piece ball valve,A newly adopted type of valve widely used in recent years; such valves are typically horizontally installed.

Insulating Ball Valve Product Features:

1Low fluid resistance; its drag coefficient is equal to that of a pipe section of the same length.

2Simple structure, compact size, and light weight.

3Tight and reliable, ball valves commonly use plastic for their sealing surfaces, offering good sealing properties, and are widely used in vacuum systems as well.

4Easy to operate, quick to open and close; from fully open to fully closed in just one rotation.90°Easy for remote control.

5Easy to maintain, the ball valve structure is simple, and the sealing rings are generally movable, making disassembly and replacement convenient.

6．When fully open or fully closed, the sealing surface of the sphere and the valve seat is isolated from the medium. The medium passing through does not cause erosion of the valve sealing surface.

7Wide application range, from a few millimeters to several meters in diameter, and suitable for both high vacuum and high-pressure conditions. Ball rotation90At all inlets and outlets, the flow should be fully spherical to cutoff the movement.

Thermal Insulation Ball Valve is a relatively new category of ball valves with several structural advantages, such as frictionless operation, easy-to-seal and less wear, and low torque for opening and closing. This allows for a reduction in the size of the actuator required. Paired with a multi-turn electric actuator,Achieves adjustable control of the medium and precise cutoff. Widely applicable in stringent cutoff conditions such as in the oil, chemical, and urban water supply and drainage industries.

Insulating ball valve operation：

1At the closed position, the sphere is held by the valve stem.[wiki]Mechanical[/wiki]Pressure is applied, pressing tightly against the valve seat.

2When turning the handwheel counterclockwise, the valve stem moves in the opposite direction, causing the bottom angular plane to disengage the ball from the valve seat.

3The valve stem continues to rise and interacts with the guide pin within the valve stem helical groove, allowing the ball to begin rotating frictionlessly.

4Up to full open position, the valve stem is lifted to the ultimate position, and the ball rotates to the full open position.

Closing Process

1When closing, rotate the handwheel clockwise, causing the valve stem to descend and the ball to start rotating away from the valve seat.

2Continue turning the handwheel, valve rodThe guide pin, embedded in the spiral groove, enables both the valve stem and ball to rotate simultaneously.90°。

3 Just before closing, the sphere rotated without contacting the valve seat.90°。

4In the final few rotations of the handwheel, the triangular flat at the bottom of the valve stem mechanically wedges against the ball, pressing it tightly against the valve seat for a complete seal.

Insulating Ball Valve Product Introduction:

1The opening and closing are frictionless. This feature completely resolves the traditional...[wiki]Valve[/wiki]Issue caused by friction between sealing surfaces affecting the seal.

2Upward-mounted structure. Valves installed on pipelines can be directly inspected and maintained online, effectively reducing downtime and cutting costs.

3Single valve seat design. Eliminates the issue of using safety affected by abnormal pressure increase of the medium in the valve cavity.

4Low-torque design. The valve rod, with a special structural design, can be easily opened and closed with just a small handwheel valve.

5Oblate sealing structure. The valve is sealed by applying mechanical force through the valve stem to press the ball wedge against the valve seat, ensuring the valve's sealing performance is unaffected by pressure difference changes in the pipeline, and reliable sealing is guaranteed under various operating conditions.。

6Self-cleaning structure with a sealed cover. When the ball is tilted away from the valve seat, the fluid in the pipeline follows the ball's sealing surface360°Uniform flow not only eliminates the local erosion of the valve seat by high-speed fluid but also washes away the accumulated deposits on the sealing surface, achieving the purpose of self-cleaning.
