Adjustable Pressure Relief Valves

Our adjustable pressure relief valves are for use with inert liquids and gases. We offer one range with a steel shutter system and the other with a PTFE shutter system. 

Both types are almost identical, the only different apart from the shutter system is the maximum working temperature. The steel shutter version has a max temperature of 200°c, whereas the PTFE version has a max temperature of 180°c.

Both have the same range of connections from 3/8" to 3". The sizes between 3/8" to 2" have a maximum pressure of 16bar, and the 2-1/2" to 3" have a max pressure of 10bar and both types have a max opening pressure of 20%. 

All of the valves have a minimum working temperature of 5°c 

Manufactured in Italy, in compliance with top European standards.
