Vacuum and pressure relief valves

Pressure valve

Pressure Valves
1″ – 14″

These valves open when the internal pressure in the tank increases and approaches predetermined safety limits.

Different models in aluminum, carbon steel, stainless steel or with fluoropolymer coating.​

Mounting by ANSI 150, PN 10, PN 16 flanges.

Screwed connection for small diameters. 

Breather valve vacuum pressure

Breather Valves
2″ – 12″

Combination of a pressure valve with a vacuum breaker valve.

Different models in aluminum, carbon steel, stainless steel or with fluoropolymer coating.

Mounting by ANSI 150, PN10, PN 16 flanges. 

Flame arrester and breather valve assembly

Flame arrester / breathing valve assembly 
1″ – 12″

This assembly is composed of either an in-line anti-deflagration flame arrester mounted between the tank and the breathing valve; or an “end of line” flame arrester mounted at the outlet of the valve on the atmospheric side..

Different models in aluminum, carbon steel, stainless steel or with fluoropolymer coating.​

Mounting by ANSI 150, PN 10, PN 16 flanges.
