Zurn 70 (3/4 Inches) Water Pressure Reducing Valve 50 Psi

Product Description

The ZURN 70 (3/4") is a water pressure reducing valve factory set to 50 PSI, designed to protect downstream plumbing systems from excessive supply pressure. Installed on the main water service entry or branch lines, it reduces high incoming pressure to a safe, stable working level that protects fixtures, appliances, and piping from pressure-related wear and failure. The valve features a 3/4 inch connection size, making it suited to standard residential and light commercial service lines. Licensed plumbers install this valve during new construction, service upgrades, or replacement of failed pressure regulation equipment.

The 70 (3/4") is commonly applied in residential water service installations where municipal supply pressure exceeds recommended working limits for downstream fixtures and appliances. It is also used in light commercial settings where a single zone or branch line requires pressure regulation. The factory set point of 50 PSI aligns with standard residential plumbing requirements, reducing the need for field adjustment at time of installation.

Key Features

• Factory set at 50 PSI for straightforward installation without field calibration
• 3/4 inch connection size fits standard residential and light commercial service lines
• Reduces incoming supply pressure to protect fixtures, appliances, and piping
• Compact form factor suited to tight mechanical room or service entry installations

Compatibility

Installation Notes

Installation must be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and relieve system pressure before removing any existing valve or making connections. Install with flow direction matching the arrow marked on the valve body, and ensure adequate access for future service or adjustment. Do not overtighten threaded connections; use appropriate thread sealant approved for potable water service.
