6 of 6 models

Ventex

BS&B Ventex explosion isolation float valve

Passive explosion isolation valve for ducts DN100 to DN600: the pressure wave of an explosion drives a float against its seat and locks the duct, in one or both directions, with no external energy.

Saf-t-Flap

BS&B Saf-t-Flap explosion isolation flap valve

Passive flap valve for inlet ducts of dust collectors, DN100 to DN1350: held open by the airflow, slammed shut and latched by the explosion pressure. No detection or control needed; combinable with venting and suppression.

Redex

BS&B Redex RSV-D active isolation slide valve

Fast-acting slide valve, DN50 to DN500, closed by a gas generator on a signal from explosion detection, protecting conveying and product lines against explosion propagation.

ESI-P

BS&B ESI-P external activated isolation valve

Active explosion isolation valve, DN100 to DN600, closed by external energy on a detector signal. Its special operating mode also gives effective protection against fires propagating through the duct.

IVE

BS&B Type IVE explosion isolation pinch valve

Fast-acting pinch valve for product lines DN80 to DN300: an explosion-protected industrial pinch valve that closes on a detector signal to stop deflagration propagation, with a full bore in normal operation.

Type IPD

BS&B Type IPD chemical isolation system

Active chemical isolation: on detection of an explosion, a suppressant cannon injects sodium bicarbonate into the connected duct or pipe, quenching the flame front before it reaches the next vessel.
