Lead Free* Series LFTP300 trap primers are installed in plumbing systems to prevent floor drain traps from losing their water seal by evaporation. It operates by sensing the pressure drop in the supply line from downstream fixtures or appliances. This trap primer features Lead Free* construction to comply with Lead Free* installation requirements and incorporates a built-in vacuum breaker which does not satisfy compliance to ASME A112.1.2. The minimum supply pressure must exceed 25 psi (172 kPa). The maximum supply pressure is 125 psi (8.6 bar).

Armas Pressure Sustaining Control Valve maintains valve upstream pressure value constant. Valve is opened when line pressure reaches adjusted valve pressure level. It ensures that pump motor within pumping systems will start without load. It also prevents positive pressure waves caused by pump during start-up. Valve controls upstream pressure value continuously and keeps it in a constant value without being affected from changes in flow rates. When no flow exists, it is closed by itself as fully tightness.
