CV Technology, Inc. products

The Interceptor-VE is a NFPA 69 compliant isolation pinch valve.  The Interceptor-VE™ valve is normally open.  Upon receiving a signal from either a pressure responder or an optical sensor the Interceptor-VE™ controller is designed to immediately signal the Interceptor-VE™ valve.   The Interceptor-VE™ valve will close in milliseconds to prevent the passage of hot particles, glowing embers, flame, or pressure from continuing to flow through the pipe. The medium of actuation is plant compressed air stored in a tank on the valve to ensure the fastest response possible under any plant conditions.

Explosion vents offer a passive and economical means of explosion mitigation.  Each explosion vent is precisely designed to burst at a given pressure to maintain the structural integrity of the protected equipment. Vents come in a variety of dimensions and models.  The CV Technology standard vent is our TLFG model. The TLFG explosion vent is a triple layer, food grade explosion vent that is domed for inherent vacuum support.  Explosion vents offer a simple installation, long service life, and quick replacement.  Standard models are available for next day shipping.

The Interceptor-HRD explosion suppression system is designed to provide an active method to protect process equipment from a dust explosion hazard.  The principle of operation for the Interceptor-HRD system is timely detection of the pressure rise during the initial stage of an explosion, followed by fast injection of an extinguishing agent.

The Interceptor-QR and Interceptor-LT are NFPA 68 compliant flameless venting devices.  Flameless vents are comprised of two parts, an explosion vent and a quencher. The quencher is constructed of multiple layers of stainless steel mesh supported by a metal frame.  Ignition inside a protected vessel causes pressure to build rapidly. The explosion vent is designed to relieve the pressure. Burning dust, flames and hot gases all exit through the vent opening into the quencher. The quencher then takes over to absorb the heat from the flame and hot gases. The mesh acts as a heat sink to quench the temperature and break the chain reaction of the explosion. The flame is completely retained in the quencher making flameless vents safe for indoor use or in occupied work spaces. Flameless vents are the ideal passive explosion mitigation device.

A versatile explosion vent design, the TLFG is specially designed to handle any application or process. The composite, domed vent construction provides high vacuum resistance and high-pressure cycling resistance. They can also be paired with a flameless vent to provide indoor venting or ducted to a safe area through a duct. The TLFG explosion vent is a domed composite explosion vent. Three-layer comprise the explosion vent with 304 stainless steel product contact and PTFE sealant layer. Features include an integrated burst indicator and a variety of gasket materials.

An economical explosion vent, the SLFG provides the most cost effective solution for explosion venting. An integrated vent frame and gasket allows for simple, quick installation and replacement. Ideal for applications with lower pressure cycling or atmospheric pressures the SLFG can be applied to dust collectors, storage vessels, or conveyors. Features include optional burst indicator and relay module.

The ultimate sanitary design, the TLST explosion vent is USDA Dairy certified model for use any food or dairy applications. The composite design can be paired with a flameless vent to provide indoor venting or ducted to a safe area through a duct. The TLST explosion vent is a domed composite explosion vent. Three layers comprise the explosion vent with polished 316 stainless steel product contact and PTFE sealant layer.  Features include an integrated burst indicator.

The Interceptor-QR is a NFPA compliant and FM Approved flameless venting device. Often referred to as a quench tube, round style flameless vents offer the advantage of optimum venting efficiency to handle all applications. Dusts approved for the Interceptor-QR include organic material, melting, fibrous, and light metal dusts.

The Interceptor-LT is a NFPA compliant flameless venting device. Designed as an economical solution for flameless venting the I-LT features a painted carbon steel frame with stainless steel mesh insert. The rectangular cross-section allows for maximum vent area and sleek installation.

The Interceptor-EV is a NFPA compliant flameless venting device. Specially designed with a slim, elongated profile this flameless vent is ideal for bucket elevators and conveyors where installation locations are limited. The lighter frame is painted carbon steel with a stainless steel mesh insert. The compact design allows for easier handling and installation. Comprised of both the flame arrestor and explosion vent the Interceptor-EV can be rearmed in the field. The standard TLFG model explosion vent allows this flameless vent to be used on variety of difficult applications including bucket elevators, conveyors, and small vessels.
