The Super-Chek® design has been proven over the last 15 years to be the standard for air compressor in-tank check valves. One-piece brass bodies, stainless steel springs, and glass-filled fluoropolymer poppets all add up to long term reliability, while the eight discharge holes insure quiet operation. Valves may be disassembled for cleaning or repair. Valves are 100% tested for backflow leakage performance. 450 psi max pressure, 205oC max temperature. Female inlet with 1/8"tapped unloader port.

These cast-brass check valves have been specifically designed for installation into air compressor discharge lines. Extra-heavy walled cast brass bodies, glass-filled fluoropolymer poppets, and stainless springs resist corrosion, and insure long life. A plugged, 1/8 NTP unloader port is standard. 250 psi maximum pressure, 245°C maximum temperature. These valves should be mounted with the hex nut in the down position to ensure optimum drainage.
