STAINLESS STEEL LOW BACK PRESSURE REGULATOR
Description
The diaphragm back pressure regulator protects compressed air devices from excessive pressure.
If the pressure setpoint is exceeded, overpressure is vented into the atmosphere until the setpoint is
reached again. It is recommended to choose a pressure range as low as possible.
Media
compressed air, gases
Adjustment
by adjusting screw for D3100-02 to - 1A, with locknut
by T-handle for D3100-12 and -16, with locknut
Gauge port
G¼ on both sides of the body, screw plugs supplied
Temperature range
0 °C to 80 °C / 32 °F to 176 °F, FKM or EPDM
0 °C to 130 °C / 32 °F to 266 °F, high temperature version
for appropriately conditioned compressed air down to -20 °C / -4 °F
or low temperature version down to -40 °C / -40 °F
