FAQ

What is the thread size for the pneumatic connections on this LR-D-7-MIDI regulator?

The LR-D-7-MIDI regulator is available with various standard port sizes. While not marked on the body, the most common connection for the MIDI size is G1/2 or G3/8. It is crucial to measure the port threads before installation to ensure compatibility with your fittings.

Can I use this regulator without a pressure gauge?

Yes, this model can be operated without a pressure gauge. The front port, typically used for a gauge, is sealed with a plug. For applications requiring precise pressure monitoring, a compatible G1/8 gauge can be easily installed in this port.

How do I lock the pressure setting on this regulator?

The blue rotary knob features an integrated lock. To set the pressure, pull the knob upwards to unlock it. Turn the knob to adjust the pressure to the desired level. Once set, push the knob down to lock it in place, preventing accidental adjustments.
