Additional Details

This 1 inch Watts LFU5B-Z3 Lead Free Water Pressure Reducing Valve is designed to protect plumbing systems by reducing high incoming water pressure to a sensible level and reducing water consumption in commercial, industrial, and residential applications.

It features a lead free cast copper silicon alloy body and can be easily serviced without removing the valve from the line.

Features

  • Lead Free* cast copper silicon alloy body construction ensures compliance with lead-free installation requirements.
  • Bypass feature controls thermal expansion pressure.
  • Reinforced EPDM diaphragm is high-temperature resistant for hot water applications.
  • Integral stainless steel strainer is easily removable for cleaning.
  • Replaceable seat module allows for easy maintenance.
  • Serviceable in line for quick and easy part replacement without special tools.
  • Z3 sealed spring cage with corrosion-resistant stainless steel adjusting cage screws for accessible outdoor or pit installations.

Operation & Maintenance

  • This valve reduces incoming water supply pressure up to 300 psi (20.7 bar) to an adjustable range of 25-75 psi (172-517 kPa), with a standard factory setting of 50 psi (345 kPa).
  • The standard bypass feature allows water to flow back through the valve into the main supply when thermal expansion causes outlet side pressure to exceed the main supply pressure.
  • All parts are designed for quick and easy serviceability, often without needing to remove the valve from the line.

FAQs

What is the primary function of the Watts LFU5B-Z3 valve?

The primary function of the Watts LFU5B-Z3 valve is to reduce high incoming water pressure to a safe, sensible level. This protects plumbing system components from damage and helps to reduce water consumption.

What type of connections does the 1 inch LFU5B-Z3 valve use?

The 1 inch LFU5B-Z3 valve features an NPT threaded female union inlet and an NPT threaded female outlet. This allows for straightforward installation into standard plumbing systems.

What is the adjustable pressure range for this valve?

The adjustable reduced pressure range for this valve is 25-75 psi (172-517 kPa). The valve comes with a standard factory setting of 50 psi (345 kPa).

Is this valve suitable for hot water applications?

Yes, the Watts LFU5B-Z3 valve is suitable for hot water applications with a temperature range of 33°F to 180°F (0.5°C to 82°C) due to its high-temperature resistant reinforced EPDM diaphragm.

What does the bypass feature do?

The bypass feature allows water to flow back through the valve into the main supply. This helps to control pressures caused by thermal expansion on the outlet side of the valve when they exceed the main supply pressure.
