Flame Arrestors & Tank Venting

Series 850 Pipe-Away Pressure Vacuum Relief Valves

The 850 series Relief valve is designed to provide pressure and vacuum relief in applications that require hazardous vapors to be piped away, rather than released into the atmosphere.  Available in sizes 2'' through 10''.  Standard pressure and vacuum settings are 1/2 ounce or 1 inch of water column.  Seats and pallets are non-corrosive advanced composite materials or stainless steal.

  

                 

 

Series 950 Vent To Atmosphere Pressure Vacuum Relief Valves

Series 7 Inline Flame Arrestor

 

The Series 7 models are designed to prevent the propagation of flame through venting systems under specified conditions.  The element assembly is easily removed for maintenance or replacement while maintaining the piping integrity.  Installation can be vertical or horizontal, within 20 pipe diameters or a maximum of 20 feet with one bend before the potential ignition source for group "D" gases.

 

 

 

 

 

High Pressure Deflagration Arrestor

 

High Pressure Deflagration Flame Arrestors surpass standard flame arrestor performance in applications involving extended lengths of pipe with one bend, elevated operating pressures and extended flam stabilization on flame cell element.  These units are bi-directional and can be installed vertically or horizontally.  Elements are available for group B/C and D gases.

 

 

 

 

      Detonation Flame Arrestor

 

Detonation Flame Arrestor units are bi-directional and can be installed vertically or horizontally at great distances from the ignition point and withstand high pressure deflagration and detonations.  They are also designed to provide protection against continuous burning for a specified period.  Elements are available for group B/C and D gases.

 

 

 

 

       

Pressure Vacuum Relief Valve With Flame Arrestor

 

The 950 series relief valve with Series 7 flame arrestor allows a storage tank with flammable liquids or solvents to breath, thus maintaining a safe internal working pressure while protecting against fire and explosion from outside sources of ignition.  Available in sizes 2'' through 10''.  Standard pressure and vacuum settings are 1/2 ounce or 1 inch of water column.  Seats and pallets are non-corrosive advanced composite materials or stainless steel.  For closed in vapor collection systems, use a 850 series relief valve with a ENARDO detonation flame arrestor.

 

 

 

                                   

  

 

 

 

 

 

Series 2000 Emergency Pressure Relief Vent

The Series 2000 is available in 4'', 8'', 12'', 16'', 18'', 20'' and 24'' sizes. They provide pressure relief only for those applications that require accurate large volume venting.

 

 

 

Series 1000 Lock Down Hatch

 

The series 1000 hatch provides access into storage tanks.  When closed it assures a vapor tight seal that prevents leakage and evaporation loss.  It is designed for easy installation, inspection and maintenance providing trouble free operation.

 

API - (16) 11/16'' holes on an 10-3/8'' circle.

 

 

Model A-L Dead Weight Gauge Hatch

 

The Model A-L is a dead weight pressure vacuum relief gauge hatch utilizing an oblong base.  This model was designed to meet the demand for a hatch on a tank requiring a larger opening than the popular 8'' round.  Standard settings are 2 oz. pressure and 4/10 oz. vacuum relief.
