Pressure/Vacuum Relief
Enardo Series 950 Pressure Vacuum Relief Valve: The Enardo Series 950 is part of our line of high-performance pressure vacuum relief valves and is designed with features that exceed the performance of standard valves on the market, particularly in very cold ambient conditions and applications involving sticky materials. This valve provides pressure and vacuum relief for normal venting requirements while maintaining a safe internal working pressure to prevent the routine expulsion of waste gas to the atmosphere.
Varec Series 2010B/2020B Pressure & Vacuum Relief Valves: Weight-loaded relief valves that protect tanks from damage or deformation, minimize emissions to the environment and loss of product due to evaporation. The 2010B and 2020B are designed for use on atmospheric and low pressure storage tanks or for emergency venting on smaller tanks. The 2010B vents to atmosphere; the 2020B allows vapors to be piped away for recovery.
Tank Vents
Enardo Model 2500 Emergency Relief Vent with Vacuum: Enardo Model 2500 Emergency Relief Vents with Vacuum provide an emergency pressure relief opening for storage tanks when exposed to overpressures not handled by standard tank vents. When properly sized, this vent provides the capacity meet API Standard 2000 NFPA 30 and OSHA (29 CFR 1910.106) for emergency venting due to fire exposure, and offers high-capacity vacuum flow for emergency pump-out of product. The Model 2500 also provides quick, easy access for tank inspection and maintenance.
Varec Series 221 Emergency Pressure Relief Manway Covers: The 221 Series is designed to provide emergency venting of low pressure storage tanks and vessels. 221 Series manways protect tanks against costly rupture or implosion. The 221P provides emergency pressure relief only with vacuum relief supplied by a separate breather valve. The 221PV provides both pressure and vacuum relief.
Flame Arrestors
Enardo DFA Series Detonation Flame Arrestors: Enardo Detonation Flame Arrestors provide protection against flame propagation in piping systems that are manifolded or have long run-up distances. The design is unique with larger flame channels that limit plugging and make cleaning easier. These arrestors are bi-directional and are proven to stop an ignited flammable vapor mixture approaching from either direction and traveling at subsonic or supersonic velocities. Its flame element offers maximum flow to pressure drop characteristics.
Varec Series 5000/5010 Flame Arresters: Group ‘D’ end-of-line flame arresters with a unique extensible bank frame designed to stop the propagation of flame from external sources. The 5000 and 5010 Series, Group ‘D’, end-of-line flame arresters are used in gas piping systems, petroleum storage tank roofs and digester covers to prevent the propagation of a flame into the system.
