Symmons 5-400NW Thermostatic Mixing Valve Cartridge

Product Description

The SYMMONS 5-400NW is a replacement thermostatic mixing valve cartridge designed for use in Tempcontrol valve assemblies with 3/4-inch inlets and 1-inch outlets. It controls mixed water temperature through a stainless steel piston and thermal motor, maintaining output within a set range of 60 degrees F to 120 degrees F. A Turbulator element is integrated into the design to improve thermal response and mixing efficiency. This cartridge is installed by licensed plumbers performing routine maintenance or system rehabilitation on thermostatic mixing valve installations in both residential and light commercial applications.

This cartridge is suited for Tempcontrol thermostatic valve assemblies requiring a direct OEM-style replacement. It is appropriate for use in domestic hot water systems where scald protection and temperature stabilization are required. The 60 to 120 degrees F operating range covers standard domestic water delivery applications. Plumbing contractors performing valve service or retrofit work on aging Tempcontrol installations will find this cartridge a direct fit for assemblies with 3/4-inch inlets and 1-inch outlets.
