All You Need to Know About Ball Valves

A plastic ball valve is a type of valve that utilizes a hollow ball with a central aperture to control the flow of fluids. The ball rotates 90 degrees to either block or permit the movement of fluids. Plastic ball valves are integral components in fluid control systems, offering efficient and cost-effective solutions for regulating the flow of liquids and gases. They are particularly well-suited for applications requiring corrosion-resistant, lightweight, and durable components.

Plastic ball valves are crafted from a variety of plastics, including PVC, CPVC, PPR, PP, PPH, PVDF, and others. They are commonly employed in pipelines, irrigation systems, and other applications where corrosion-resistant and lightweight valves are necessary. Plastic ball valves are available in a range of sizes and styles. They can be threaded, socket-welded, or flanged, catering to diverse applications.

Ball valves are versatile and reliable valves suitable for various applications. They are easy to install and maintain, boasting a long operational lifespan. 

PVC Ball Valves

Quick Actuation

A simple 90-degree turn is sufficient for full operation, allowing for rapid opening and closing.

Low Torque

Requires less force to operate, contributing to energy efficiency.

Corrosion Resistance

Inherently resistant to corrosion, making them ideal for applications involving aggressive fluids.

Leak-Proof

Designed for tight sealing to minimize leaks.

Cost-Effectiveness

Generally more affordable than metal valves, both in terms of initial cost and maintenance.

Low Maintenance

These valves are less prone to wear and tear, reducing long-term operational expenses..

Installation Method

Multiple Connection Options: Offered in threaded, socket-welded, and flanged types to suit varied requirements.

Size Flexibility

Can be manufactured in a range of sizes to meet specific needs.

Easy to repair

The ease of repair often requires less specialized labor, leading to cost savings.

Understanding Plastic Ball Valves

Valve Body

  • Function: Serves as the framework that houses all the components, connecting the valve to the pipeline system.
  • Design: Can be a single-piece, two-piece, or three-piece body.
  • Materials: Available in PVC, CPVC, PPR, PP, HDPE, PPH, and PVDF.
  • Customization: Material selection can be tailored to specific requirements.

Sealing Ring

  • Location: Inside the valve body.
  • Material: Generally made from TPE or TPV.
  • Customization: Can be modularly replaced based on the corrosiveness of the fluid passing through the valve.

O-Ring

  • Usage: Used for sealing the handle and the valve stem.
  • Material: Typically crafted from EPDM or NBR.

Ball Core

  • Function: Key component for controlling flow, situated inside the valve body.
  • Operation: Rotates 90 degrees to control fluid flow.
  • Material Options: Available in PVC, CPVC, PPR, ABS, PP, HDPE, PPH, and PVDF.
  • Customization: Material can be tailored based on the corrosiveness of the medium.

Valve Stem

  • Function: Connects the inner ball to the handle or actuator.
  • Material: Common materials include PVC, CPVC, PPR, PP, HDPE, PPH, and PVDF.

Branding Cover

  • Location: Sits between the valve stem and handle.
  • Function: Aesthetically pleasing and can be customized with the client’s branding.

Sectional view of PVC ball valve

Handle

  • Function: The part through which force is applied to rotate the valve.
  • Material: Typically made from ABS.

The handle style can be changed according to market preference or customer choice. 1/2-2″ for short handle, 2-1/2″-4″ for long handle.

How Ball Valves Work?

Ball valves offer flexibility in flow direction, ranging from bidirectional to multi-directional options. Bidirectional valves permit flow in both directions, suitable for systems requiring reverse flow. The design of three-way valves provides diversion capabilities. More complex designs enable the separation and convergence of multi-directional flows, making them an ideal choice for intricate fluid systems.

A key advantage is their swift operation – merely a quarter turn is needed to open or close the valve. This operational speed enhances system efficiency and minimizes energy consumption.

Factors to Consider When Choosing Ball Valves:

CPVC ball Valve

#1 Material Selection:

Choose appropriate materials such as PVC, CPVC, or PPH based on the fluid type, temperature, and corrosiveness.

#2Traffic requirements:

Consider the required total menstrual flow.

#3 Directional Flow:

Select between two-way valves for simple bidirectional flow and three-way ball valves for diversion or convergence systems.

#4 Connection Type:

Choose socket, threaded, or flanged connections for valve installation.

#5cPipe Diameter:

Ball valves are not suitable for pipes with diameters greater than 110mm (4″) for shut-off or control purposes.

#6 Pressure Rating:

Check the pressure rating to ensure the valve can withstand the system’s operating pressure.

#7 Sealing Options:

Evaluate the compatibility of sealing materials like EPDM or NBR with the fluid to minimize leaks.

#8 Operating Speed:

If quick operation is needed, ensure the valve offers a quarter-turn operation.

#9 Maintenance:

Opt for valves that are easy to disassemble and maintain, especially for frequently used valves.

#10 Cost:

Balance between upfront costs and long-term operational expenses.

Classification of Ball Valves Based on Valve Body Structure:

One-Piece Ball Valve:

The valve body of the ball valve is molded as a single unit. It cannot be repaired, and if it becomes faulty, the entire valve needs to be replaced.

Two-Piece Ball Valve:

The valve body of the ball valve is molded into two separate parts. The valve body and ports are joined together using threads, adhesive, or friction welding after molding.

Three-Piece Ball Valve:

Modular design: Three parts are injection molded separately, and then the ports are sealed with the valve body through threads.

Single Union Ball Valve:

The ball valve body and one end port are molded separately. The port is designed to be removable, which is convenient for installation and maintenance of the valve in the pipeline.

True Union Ball Valve:

The ball valve body and both end ports are molded separately. The ports are designed to be movable, facilitating easy installation and maintenance of the valve in the pipeline.

Types of Ball Valves Based on Functionality

Shut-Off Type
This type features a 90-degree rotation of the ball core via the valve stem to halt fluid flow in the pipeline.

Diverter Type
Three-way valves allow fluid to be diverted, combined, or stopped by rotating the ball core, offering flow regulation.

Guide to Buying Ball Valves:

1. Check the valve raw material performance should be consistent with the raw material manufacturer’s instructions.
2. Check whether the valve diameter DN and nominal pressure PN are marked on the valve body.
3. The valve body should be marked with the manufacturer’s name or trademark.
4. Make sure that the valve has passed the sealing test before leaving the factory.
5. Make sure the valve complies with relevant national or international standards, such as DIN 16962 or ANSI B16.5, etc.
