FAQ

Question?
What is the function of a ‘relieving’ type regulator like the PRA2D-1BDA?

A relieving (or self-relieving) regulator can vent excess downstream pressure to the atmosphere if it rises above the set point. This is crucial for applications where downstream pressure might increase due to external forces, ensuring the system pressure remains stable at the desired level.

Question?
What is the recommended inlet pressure for this regulator to achieve the specified 2-130 PSI outlet range?

For optimal performance and to achieve the full outlet range, the inlet pressure should be consistently higher than the desired maximum outlet pressure. A common rule of thumb is to supply an inlet pressure at least 10-15 PSI (approx. 1 bar) above the maximum required outlet pressure of 130 PSI.

Question?
Can this regulator be panel mounted?

Yes, the PRA2 series regulators are designed to be panel mountable. However, the panel mounting nut is an accessory that is not always included with the base unit. Please check product images or inquire about its inclusion if this is a requirement.
