RP Pressure Regulators - Data Sheet

Product catalog summary

Materials and Construction Features
The document outlines the construction features of a "Fail to open" regulator, emphasizing high-precision control, a wide regulated pressure range, and easy maintenance without removing the body from the line. The materials used include EN AB 46100 UNI EN 1676 Aluminium, 400-18L UNI ISO 1083 Cast iron, ASTM A216 WCB Steel, and NBR Clothed rubber.

Available Versions
There are several versions of the regulator available:

RP/011, RP/022, RP/033: without slam shut valve
RP/011/66, RP/022/66, RP/033/66: with slam shut valve
