Most Common Types of PVC Valves

PVC valves are vital flow control components in plumbing and industrial systems. Their corrosion resistance, durability, and affordability make them a top choice for a wide range of piping networks, from water treatment plants and irrigation lines to chemical conveyance systems. 

This resource will cover the 10 most common types of PVC valves, their design, available size range, and best matched applications. Whether you need precision flow control, backflow prevention, or valves for small spaces, there is a PVC valve to meet your needs. 

Common PVC Valve Types

1. PVC Ball Valves 

• Key Functionality: These quarter turn valves are simple to operate and highly effective for controlling liquid flow. The ball inside the valve aligns with the flow path when opened and blocks the flow when closed. 
• Applications: Suitable for water supply systems, irrigation setups, and industrial operations requiring reliable on/off control. 
• Size Range: Common sizes range from 1/2 inch to 6 inches.

2. PVC Gate Valves 

• Key Functionality: PVC gate valves feature a flat or wedge shaped gate that moves up or down to regulate flow. They are best used for fully opening or shutting off flow rather than for throttling. 
• Applications: Frequently seen in water treatment plants, distribution networks, and industrial piping systems. 
• Size Range: Commonly available in sizes from 1/2 inch to 4 inches.

3. PVC Check Valves 

• Key Functionality: Designed as non-return valves, PVC check valves allow flow in one direction and automatically prevent backflow during changing system conditions. 
• Applications: Often used in sewer systems, irrigation networks, and other backflow-sensitive setups. 
• Size Range: Common sizes range from 1/2 inch to 6 inches.

4. PVC Butterfly Valves 

• Key Functionality: Compact and efficient, PVC butterfly valves are quarter-turn valves that use a rotating disc to regulate or isolate flow. They are ideal for applications that need quick shut-offs or regular flow adjustments. 
• Applications: Frequently used in HVAC systems, chemical processing, and water treatment applications. 
• Size Range: Commonly available in sizes ranging from 2 inches to 12 inches.

5. PVC Actuated Ball Valves 

• Key Functionality: Actuated ball valves automate flow control by using electric or pneumatic actuators to operate the valve with precision and minimal manual effort. They offer quick, reliable on/off control remotely or as part of a wider system.
• Applications: Ideal for applications requiring automation or frequent operation, such as industrial systems, water treatment plants, irrigation, and process control.
• Size Range: Typically available in sizes from 1/2 inch to 6 inches.

6. PVC Compact Valves 

• Key Functionality: Designed for installations with limited space, PVC compact valves are a streamlined version of other popular valves. They provide specific functionality like blocking or regulating flow depending on their type, such as ball or check. 
• Applications: Ideal for tight environments in plumbing systems, compact machinery, and specialized equipment. 
• Size Range: Commonly available in sizes from 1/4 inch to 4 inches.

7. PVC 3 Way Ball Valves 

• Key Functionality: PVC 3 way ball valves feature a rotating ball that diverts flow between three ports, available in T or L configurations for different flow patterns. 
• Applications: Used in mixing or blending processes, bypass operations, and systems needing multi directional flow. 
• Size Range: Common sizes range from 1/2 inch to 2 inches.

8. PVC Diaphragm Valves 

• Key Functionality: PVC diaphragm valves are built for precision flow control and pressure moderation in process systems. With an internal diaphragm made from durable modern materials, these valves can handle varying flow rates and relieve excess system pressure. 
• Applications: Well suited for chemical synthesis, water and wastewater treatment, chlorination systems, food and beverage processing, and healthcare.
• Size Range: Available in sizes from 1/2 inch to 6 inches.

9. PVC Wafer Check Valves 

• Key Functionality: These slim, lightweight valves prevent backflow and are designed to be installed between flanges. They rely on internal fluid pressure to open and close. 
• Applications: Perfect for HVAC systems, water treatment plants, and various industrial pipelines. 
• Size Range: Typically found in sizes from 1 inch to 8 inches.

10. PVC True Union Ball Valves 

• Key Functionality: PVC true union ball valves feature fully removable union connections designed for easy maintenance that lets you install, clean, or replace the valve without disrupting the rest of your system.
• Applications: Commonly used in swimming pool systems, water treatment plants, temporary pipelines, and installations where regular cleaning or troubleshooting is expected. 
• Size Range: Available in sizes from 1/2 inch to 4 inches.
