Blast Valves with Prefilter

We offer heavy duty blast valves with prefilter to protect the interior of a shelter from blast waves caused by outside explosions. A prefilter, with an efficiency of ~ 90%, is fully integrated. Normally, the valve is open and it closes up in case of an outside explosion. CPI produces different types of blast valves to withstand different levels of blast waves: 3, 11, 40, 60bar and even higher reflected pressure.

All valves are tested and certified for compliance to the applicable Singaporean, Israeli and Swiss standards.

Features:

• Double-action valve (protects against explosive and implosive waves)
• Maintenance-free
• Resistant against high temperatures and corrosion
• All steel parts are phosphate treated and finished with a powder coating
