Watts 3/4inch 3L 150PSI Pressure Relief Valve 0011917

Description

The Watts 3/4″ 3L 150 PSI Pressure Relief Valve 0011917 is a vital safety feature for protecting domestic storage tanks and tankless water heaters from excessive pressure build-up. Here’s a breakdown of its key features and functions:

Function:

• Relieves excess pressure in water tanks and heaters: If water pressure exceeds the set limit of 150 PSI, the valve automatically opens and releases water, preventing potential tank ruptures or explosions.
• Protects against thermal expansion: As water heats up, it expands, potentially exceeding safe pressure limits. The valve releases excess pressure and maintains a safe operating range.
• Complies with safety standards: Meets ANSI Z21.22, ASME, and CSA standards, ensuring reliability and performance.

Key Features:

• 3/4-inch inlet and outlet connections: Fits standard plumbing connections for most residential water heaters and tanks.
• Bronze construction: Durable and corrosion-resistant for long-lasting performance.
• Poppet-type valve: Provides reliable and quick pressure relief action.
• Test lever: Allows manual testing of the valve to ensure proper functionality.
• Pressure range: 75-150 PSI: Adjustable within this range to adapt to specific system requirements.
• Compact design: Easy to install in tight spaces around water heaters and tanks.

Applications:

• Domestic hot water storage tanks
• Tankless water heaters
• Residential hydronic heating systems
• Boiler systems

Things to Consider:

• System compatibility: Ensure the valve’s size, pressure rating, and material match your specific system requirements.
• Professional installation recommended: While DIY installation is possible, consulting a qualified plumber is recommended for optimal performance and safety, especially when dealing with water connections and pressure relief systems.
• Regular maintenance: Periodically test the valve using the lever to ensure its functionality and prevent build-up or rust.

Alternatives:

• Watts offers similar pressure relief valves in different sizes and pressure ratings to suit varying system needs.

Overall, the Watts 3/4″ 3L 150 PSI Pressure Relief Valve 0011917 is a reliable and affordable choice for protecting your water heater and tank from dangerous pressure build-up. Its durable construction, adjustable pressure range, and easy installation make it a popular option for both homeowners and professionals.
