The First of it's kind...
We are proud to announce the Interceptor® -QV® a new patented explosion isolation device. Based in the principles of flameless venting, this quench valve will transform the way you care for clean air lines. View Brochure

Slide Passive Isolation Device The Interceptor® -QV® is a new patented explosion isolation device built with the principles of flameless venting. A stainless steel mesh cartridge in the center of the device works to stop a deflagration. If a deflagration propagates through the clean return line it will make contact with the mesh cartridge. The cartridge removes energy from the flame front of the deflagration as it passes through the torturous path of the mesh, forcing the flame to transfer its energy to the high surface area of the mesh, thereby quenching the deflagration and not allowing any flame to pass beyond the Interceptor® -QV.®

All of this takes place passively and automatically governed by the laws of physics, there is no reliance on any electromechanical processes, to achieve this result.

The Interceptor®-QV® uses a patented system where a differential pressure switch continuously monitors the pressure drop across the mesh cartridge, alerting operators if buildup of dust occurs on the mesh. The pressure drop monitoring system on the Interceptor®-QV® gives facility operators peace of mind, knowing that the condition and status of the mesh cartridge is continuously monitored assuring them of passive protection. Another patented feature of the Interceptor®-QV® is an integrated thermocouple, which when exposed to the intense heat of a deflagration will indicate, via relay, that the system has been involved in an event.
Pressure drop monitoring - device has the ability to continually measure the pressure drop to let you know if the mesh cartridge should be changed.

Thermal sensing and signaling - monitoring to let you know if the unit has seen flame or a deflagration.

Replaceable mesh cartridge - removable mesh cartridge for easy maintenance without removing the device from the process.

Passive - no moving parts and no maintenance


Stainless Steel Mesh
The quenching cartridge is composed of stainless steel mesh, which absorbs energy to extinguish the deflagration.
