3pc female thread ball valve

What is the 3pc female thread ball valve ?

3pc female thread ball vlave is a kind of valve which the opening and closing parts(ball) are driven by the valve stem , and around the ball valve axis for rotating movement of the valve , the valve body is consist of 3 parts, the performance is better than 2pc female thread ball valve.

Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff applications, where they are often preferred to gate and globe valves, but they lack their fine control in throttling applications.

Ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a “floating ball”) to control flow through it. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve’s status.

Ball valve specification

Main material sheet

Product Characteristics

1. 3pc body design
2. Thread can be made to NPT, BSPT , BSPP and so on , which can meet different countries’ standard
3. The handle can be made to long handle, butterfly handle
4. Low torgue, it is easy to open and close
5. Manufacturing standard can be ANSI, ASME, DIN , GB and Europe standard
6. The test rate is 100% , each valve will be tested before the ball valves are sold to customers’ hand

Advantages

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.
2. Simple structure, small size, light weight.
3. Tight and reliable, the sealing surface material of the current ball valve is widely used in plastic, good sealing, and has been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, from full open to full closed as long as the rotation is 90°, convenient for long-distance control.
5. Easy maintenance, simple structure of ball valve, sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the erosion of the sealing surface of the valve will not be caused when the medium passes through.
7. Wide range of application, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied. When the ball rotates 90 degrees, the spherical surface should be presented at the inlet and outlet, so as to cut off the flow.
