CPVC Ball Valve

A CPVC ball valve is a flow control device that operates using a spherical ball with a hole (also known as a bore) through the middle. When the valve handle is turned, the ball rotates to align the bore with the flow path—allowing fluid to pass through. When turned 90 degrees, the solid side of the ball blocks the flow entirely, creating an airtight seal. By convention, 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. The shut position 1/4 turn could be in either a clockwise or counter-clockwise direction.

CPVC 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 and control applications, where they are often preferred to gates and globe valves, but they lack the fine control of those alternatives in throttling applications.

Type of CPVC Ball Valve

Standard Port CPVC Ball Valve

These types of Cpvc ball valves have smaller ball and port than the full port ball valves. This valve has a low cost. However, the fluid flow in this valve is somewhat restricted due to the size of the pipe.

V Port CPVC Ball Valve

The “V” in a V-port valve denotes the ball design or design of the seat. This type of valve gives you more control to efficiently open and close the fluid flow. It has an almost linear flow.

Multi-Port CPVC Ball Valves

It has 3 or 4 directions with an L or T-shaped hole in the middle of the valve. A T-shaped valve has the ability to connect any pair of ports. The L-shaped valve can link the middle port to the side port.

Reduced Port CPVC Ball Valve

The reduced port cpvc ball valves are also called RB or reduced bore valves. In this valve, the flow area is less than the pipe, and the fluid flowing by the valve is one pipe size less than the pipe size of the valve. The reduced-port valve causes a pressure loss in the pipeline.

Full Port CPVC Ball Valve

These valves have more cost than other types of ball valves. The oversized balls in full-bore ball valves reduce friction drop because the hole in these ball valves has a similar size to the pipe. Therefore, it has more size than other valves, but it does not limit the flow rate.

Single Body or One-Piece CPVC Ball Valve

This type of ball valve has a solid cast body to reduce leaking issues. The body of this valve is not divided into pieces like split pieces valves.

Two-Piece CPVC Ball Valve

The body of the two-piece ball valve is divided into two pieces; one piece contains one end joint and body, the second piece is attached to the 1st piece, fixes the trim in its position, and also contains the second end joint.

Three Piece CPVC Ball Valve

The body of this valve is divided into three parts (i.e., a body and two end caps)—all of these parts are connected to each other via bolt connection. The design of the three-piece valve ensures easy removal of the central valve part (the part containing the seat, stem, and ball) from the pipe.

Top Entry CPVC Valve

It is a type of ball valve that assembles the ball from its top side part. This design allows the seats and ball to be maintained without valve removal from the pipeline. It is best suitable for large systems. You can also clean it without removing it from the pipeline.
