Description:
Diaphragm back pressure regulators protect pneumatic devices
against overpressure. If the pressure exceeds the setpoint,
the pressure valve exhausts to the atmosphere until the pressure
level is below the setpoint. It is advisable to select the
pressure range as near as possible to the maximum setpoint.
Media: compressed air or non-corrosive gases
Overpressure: max. 17 bar
Adjustment: by handwheel with locknut
Gauge_port: 1/4˝ NPT on both sides of the body, screw plugs supplied
Mounting_position: any
Temperature_range:
0 °C to 90 °C / 32 °F to 194 °F,
for appropriately conditioned compressed air down to -40 °C / -40 °F
Body: aluminium die-cast
Elastomer: NBR/Buna-N, optionally FKM
Inner_valve: stainless steel, brass, aluminium and cadmium-plated steel
