Review HAYWARD Air operated 3/4 In Cpvc Ball Valve 150 Psi

The **Hayward PMYB-1120 Air-Operated 3/4" CPVC Ball Valve (150 PSI)** is a high-performance, durable solution designed to deliver precise control and reliability in demanding pool and spa automation systems. Engineered with a robust **3/4-inch CPVC body**, this valve is built to withstand the rigors of continuous use in residential and commercial water treatment applications, ensuring long-lasting performance even under fluctuating pressure conditions. The **150 PSI pressure rating** guarantees robust operation, making it ideal for high-flow systems where consistent water management is critical, such as in filtration, circulation, or chemical dosing circuits.

At the heart of this valve is an **air-operated actuator**, which provides smooth, silent, and efficient operation through the use of compressed air. This mechanism eliminates the need for manual intervention, allowing for automated control via a pool automation system or a dedicated air solenoid. The **full-port ball design** ensures minimal pressure drop and optimal flow efficiency, reducing energy consumption while maintaining peak performance. The valve s **CPVC construction** is resistant to corrosion, scaling, and chemical degradation, making it a versatile choice for both saltwater and chlorinated systems.

The **150 PSI rating** not only indicates its strength but also its compatibility with a wide range of system pressures, ensuring it can handle the demands of both standard and high-flow applications without compromising integrity. The valve s **quick-connect fittings** simplify installation, allowing for easy integration into existing plumbing setups with minimal downtime. Additionally, the **sealed ball mechanism** prevents leaks and ensures a tight shutoff, which is essential for maintaining system efficiency and preventing water waste.

Ideal for use in **pool pumps, filters, heaters, and chemical feed systems**, the Hayward PMYB-1120 is a trusted component in modern pool automation. Its **durable yet lightweight design** makes it easy to install in tight spaces, while its **reliable air operation** ensures consistent performance over thousands of cycles. Whether used in a residential backyard pool or a large commercial spa facility, this valve delivers the precision and durability required to keep water treatment systems running smoothly. With Hayward s reputation for quality and innovation, the PMYB-1120 is a dependable choice for professionals and DIY enthusiasts alike who demand performance without compromise.

### **Pros and Cons of buying a Hayward PMYB-1120 Air-Operated 3/4" CPVC Ball Valve (150 PSI)**

#### **Pros:**

1. **Reliability and Durability** Hayward is a well-known brand in pool and water treatment equipment, known for producing high-quality, long-lasting components. The air-operated ball valve is designed to handle frequent use without wear, making it suitable for automated pool systems.

2. **Compatibility with CPVC Piping** The valve is specifically designed for use with CPVC (chlorinated polyvinyl chloride) piping, which is common in pool plumbing. This ensures a secure and leak-free connection when properly installed.

3. **Air-Operated Mechanism** The valve is controlled via air pressure, which means it can be integrated into automated pool systems (e.g., with a timer or controller). This eliminates the need for manual operation, improving convenience and efficiency.

4. **High Pressure Rating (150 PSI)** The 150 PSI rating means the valve can handle standard pool system pressures without risking failure, making it suitable for most residential and small commercial applications.

5. **Easy Installation** As a standard ball valve, it features a simple on/off mechanism that is straightforward to install, especially for those familiar with pool plumbing. The 3/4" size is common, reducing the need for custom fittings.

6. **Corrosion Resistance** CPVC is resistant to corrosion and chemical degradation, which is beneficial in pool environments where chlorine and other chemicals are present.

7. **Wide Availability of Parts** Since Hayward is a major brand, replacement parts, seals, and gaskets are widely available if maintenance or repairs are needed.

#### **Cons:**

1. **Cost** Compared to generic or non-branded ball valves, the Hayward PMYB-1120 is more expensive. While it offers reliability, budget-conscious buyers may opt for cheaper alternatives, though with potential trade-offs in longevity.

2. **Requires Air Supply** Since the valve is air-operated, it needs a consistent air source (typically from a pool s air pump or compressor). If the air supply fails, the valve may not function properly, requiring troubleshooting or manual override.

3. **Potential for Air Leaks** Over time, the valve s seals or connections could develop air leaks, leading to inefficient operation or failure to activate. Regular maintenance may be necessary to prevent this.

4. **Limited to CPVC Systems** If your pool system uses PVC, polyethylene, or other materials, this valve may not be compatible without additional adapters, adding complexity to installation.

5. **Manual Override Limitations** While convenient for automation, some air-operated valves lack a reliable manual override in case of air supply failure. This could be a drawback in emergencies.

6. **Skill Required for Installation** Proper installation is critical to prevent leaks or damage. Those without experience in pool plumbing may need professional help, adding to the cost.

7. **Potential for Sticking** Like all ball valves, prolonged use can cause the internal mechanism to stick, especially if debris or mineral buildup occurs. Regular cleaning and lubrication may be required.

### **Conclusion:**

The **Hayward PMYB-1120** is a robust, reliable choice for pool systems requiring an air-operated ball valve in a CPVC setup. Its durability, compatibility with automated systems, and high-pressure rating make it a strong option for those prioritizing long-term performance and ease of integration. However, its higher cost, dependency on an air supply, and potential maintenance needs should be considered.

For **most residential pool owners** who value reliability and automation, this valve is a **solid recommendation**, especially if the system already uses Hayward components or CPVC piping. If budget is a major concern or if the system lacks a consistent air supply, a generic air-operated valve or a manually operated alternative might be worth evaluating.

**Final Recommendation:**

If you need a dependable, long-lasting air-operated ball valve for a CPVC pool system and can accommodate the cost, the **Hayward PMYB-1120 is an excellent choice**. Ensure your system has a reliable air source and that you re comfortable with installation or have access to professional help if needed. For those on a tighter budget or with simpler setups, alternatives should be compared carefully.
