Temet blast valves for hardened shelters provide protection against blast pressures for air intake and exhaust vents.  All Temet blast valves are designed to exceed the rigorous requirements of military, civil and industrial hardened shelters.

PSV-Series Blast Valves are designed to perform in peak reflected overpressures up to 60 bars (870psi).

YV-Series Overpressure Blast Valves are used as air outlet valves and as internal pressure regulation valves. The valve is completely corrosion resistant and protects against  destructive pressures up to 3 bars (43.5 psi). Temet YV-Series Overpressure Blast Valves are also used as pressure relief valves for fire suppression systems. In these situations when an inert gas is released at a rapid rate of expansion to suppress a fire, the valve opens to release the gas. Computer server rooms, electrical rooms, telecommunications centers and command centers utilize the pressure relief valve.

PVD-Series Exhaust and Sanitary Blast Valves are designed for diesel engine exhausts and other hot corrosive applications. The PVD Series blast valves protect against peak reflected blast overpressures up to 60 bars (870psi)and provide complete protection during operational temperatures up to 650˚C (1200˚F).
