Pilot Operated Relief Valve (Vacuum Diaphragm Pilot)
L&J Technology, Shand & Jurs, Tank Fittings, Flame Arrestors, Valves & ACC, Tank Valves, Tank ValvesDesigned to meet very specific vacuum needs. The high accuracy of the valve allows the vacuum to be set between -3" of water column pressure and -5 psig using sensitive springs for discrete ranges. The valve operates as follows. -
Polyvinyl Chloride Conservation Vent (Pressure-Vacuum)
Conservation Vents, Pressure, Vacuum Vents, Shand & Jurs, Tank Fittings, Flame Arrestors, Valves & ACCDesigned for highly corrosive service where toxic liquids are stored. Excellent alternative to coated metal construction, where frequent corrosion due to the presence of pinholes is a problem. PVC valves are intended to provide pressure and/or vacuum relief on atmospheric storage tanks requiring normal venting. -
Spring Loaded Emergency Vent
Tank Fittings, Flame Arrestors, Valves & ACCThe Shand & Jurs 94250 Spring Loaded Emergency Vent is an economical solution to emergency venting on higher pressure tanks where weight palletted systems are impractical. The springs provide a tighter, more economical seal for higher operating pressures. The constant force of the springs immediately reseat the pallet after the overpressure is relieved. This minimizes VOCs and odor emissions. -
Spring Loaded Pressure Relief Vent (Spring Closed)
Pressure, Vacuum Vents, Tank Fittings, Flame Arrestors, Valves & ACCThe Shand & Jurs Model 94140 Spring Loaded Pressure Relief Vent reduces excessive venting of product in liquid storage tanks. Available for open or closed vent systems, this vent provides pressure relief by either venting vapor into the atmosphere or piping emissions in a closed loop system.
