Larsen Supply Co S-190-3 Pressure Balance Valve

Product Description

The Larsen Supply Co S-190-3 is a single-handle pressure balance valve cartridge designed to maintain a stable mix of hot and cold water in shower and tub-shower fixtures. Pressure balance valves compensate automatically for fluctuations in supply pressure, helping to prevent sudden temperature spikes or drops during use. This new-style unit is a direct replacement for Delta single-handle applications and is sold individually per card. Licensed plumbers and service technicians install this type of valve during routine maintenance, cartridge replacements, or fixture upgrades in residential plumbing systems.

This valve is suited for residential hot and cold water supply applications, specifically single-handle Delta-style shower and tub-shower valve bodies that require a new-style pressure balance cartridge. It is appropriate for use in standard domestic water systems where maintaining consistent water temperature at the point of use is required. Plumbing contractors and service professionals encounter this cartridge frequently during renovation work and service calls on Delta-compatible fixture installations.

Installation Notes

Installation should be performed by a licensed plumber. Shut off the water supply to the fixture and relieve line pressure before disassembling the valve body. Follow all applicable local plumbing codes and IPC guidelines when servicing pressure balance valves. Do not force the cartridge into the valve body; confirm orientation before seating to avoid damaging the unit or the valve body housing.
