The Watts 0121225 123Lp-3/4" is a pressure reduction valve used in household and commercial plumbing systems to control water pressure. It guards against damage from high water pressure to parts like coils, pumps, and boilers in hydronic heating and cooling systems. This valve automatically modifies the incoming water flow to maintain a constant water pressure throughout the system. It has an adjustable pressure range of 10 to 30 psi, 3/4-inch female NPT threads for simple installation, and a lead-free design. This valve increases system efficiency and prolongs the life of HVAC equipment by controlling water pressure.  Boilers, chillers, and other HVAC systems that require low water pressure regulation frequently employ the 0121225 valve.
