How does the MR SR compressed air regulator, BIT series perform rapid venting when supply pressure drops, and how should it be installed relative to the actuating valve?

The MR SR compressed air regulator, BIT series enables rapid venting after a supply pressure drop by incorporating a design that quickly releases downstream pressure when the upstream supply falls. This ensures the pneumatic system is depressurized fast for safety or reset. For correct operation, install the SR regulator between the actuating (supply) valve and the point of use.i.e., downstream of the actuating valve and upstream of the actuator or tool. Use the provided GW 1/8" BSP connection for the pressure gauge. Ensure supply pressure does not exceed 13 bar and select the appropriate output range (0â2, 0â4, 0â8, or 0â12 bar). Operating temperature must be kept up to +50Â°C.

What causes pressure drop in the MR SR compressed air regulator, BIT series, and how does its rapid venting protect downstream components?

Pressure drop in the MR SR compressed air regulator, BIT series occurs when supply pressure falls below the set output pressure or when flow demand downstream exceeds the regulatorâs ability to maintain set pressure. The regulator reduces output to match the lower supply or the flow-limited capacity, producing the observed pressure drop. The MR SRâs rapid venting function quickly exhausts downstream pressure when the supply pressure drops or when the actuator is isolated. By venting the downstream volume fast, it prevents stuck or partially actuated devices, reduces risk of unintended movement, and protects sensitive components and tooling from overpressure or slow depressurization. Installed between the actuating valve and point of use, it ensures fast and safe depressurization within the regulatorâs output ranges (0â2, 0â4, 0â8, 0â12 bar) and supply up to 13 bar, operating to +50Â°C.

Can the MR SR compressed air regulator, BIT series be used with supply pressures above 13 bar or at temperatures over +50Â°C?

No. The MR SR compressed air regulator, BIT series is specified for supply pressures up to 13 bar and an operating temperature up to +50Â°C. Using it above 13 bar or at temperatures over +50Â°C would exceed the stated limits and is not recommended.
