Blast Dampers
Halton & Flamgard Blast Dampers

Blast dampers are devices used to mitigate the effects of explosions or blasts in various industrial, commercial, and residential settings. They are designed to minimize damage to structures and equipment, protect personnel, and maintain the integrity of the building envelope during a blast event. Blast dampers work by absorbing, redirecting, or dissipating the energy generated by an explosion, thereby reducing the pressure and impulse caused by the blast.

When the blades are in the open position, the device does not cause significant pressure loss, noise or flow disturbance.

PVKKS – Blast Valve

The PV-KK-S blast valve block comprises three spring balanced closing elements moving in a slot and closing the air passage against the valve seats in response to both positive and negative (suction) phase of the blast. The valve blocks are mounted in structural steel frames.

PVKKSX – Blast Valve

The PV-KK-SX blast valve block comprises three spring balanced closing elements moving in a slot and closing the air passage against the valve seats in response to both positive and negative (suction) phase of the blast. The valve blocks are mounted in stainless steel frames.
