The back pressure regulator is a high-precison piston-operated regulator and 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, non-corrosive gases or liquids Overpressure: 690 bar, optionally 1034 bar Design proof pressure: 150 % maximum rated Adjustment: by knob Leakage: bubble-tight Cleaning: according to CGA4.1 and ASTM G93 Accuracy: ± 1% of pressure range Gauge port: not available Mounting position: any Temperature range: -40 °C to 80 °C / -40 °F to 176 °F, optionally high-temperature version up to 200 °C / 392 °F Body: stainless steel 316 O-Rings: NBR/Buna-N, opt. Urethane or FKM Seal: CTFE Inner valve: stainless steel 300 Valve seat: Teflon up to pressure range 103 bar, CTFE down to pressure range 172 bar
