Precision regulators with manual override Series PR
Size 1 ports: G1/4
Size 2 ports: G1/4, G3/8
Size 2 ports: G1/4, G3/8
The Series PR precision pressure regulators are ideal for applications that require a precise and stable air pressure control.
The operating principle using multiple diaphragms allows the Series PR to react to even the smallest pressure variations that may occur during use.

Coding Example
| PR | 1 | 04 | – | M | 07 |
| PR | SERIES |
| 1 | SIZE 1 = size 1 2 = size 2 |
| 04 | PORTS 04 = G1/4 38 = G3/8 (size 2 only) |
| M | TYPE OF ADJUSTMENT M = manual |
| 07 | OPERATING PRESSURE (1 bar = 14,5 psi): 02 = 0.05 ÷ 2 bar 04 = 0.05 ÷ 4 bar 07 = 0.05 ÷ 7 bar 00 = 0.05 ÷ 10 bar |
