The Shand and Jurs 94570 Combination Conservation Vent and Flame Arrester is a single, easy to configure package providing for pressure and vacuum relief, as well as positive flame stop on low pressure tanks containing flammable liquids or solvents having a low flash point. The conservation vent features cushion seated diaphragms constructed of FEP Teflon for reliability and extended service life. For high reliability, the pressure and vacuum pallets are both peripherally and center stem guided.

The Shand & Jurs Model 94020 Conservation Vent is designed utilizing over 90 years of experience in producing high quality and dependable conservation fittings. Continued design improvements provide these vents with high efficiency, maximum flow capacity and minimum leakage. The easily serviceable configuration and lightweight construction reduces maintenance and installation costs.

Diaphragms are air cushion seated and are constructed of FEP Teflon for reliability and extended service life. Teflon diaphragms contribute to high resistance to adhesion of ice and gum formations, thus assuring protection against pallet sticking to the seating surface. The body is self-draining and drip rings keep condensates from the seating surfaces. The carefully engineered body, seat, and pallet assembly results in a superior combination of tight sealing and high capacity at low over-pressure with minimal blow down.

The unitized tube bank provides maximum flow while minimizing pressure drop. Both body and tube banks are available in numerous materials to meet the requirements of your site.

Monitor Your Vents When They Are Relieving

Our MCG 1097 WirelessHART Relief Alarm can send a signal to notify the operator when a pressure device is relieving. This valuable information can be monitored and tracked.

The MCG 7030 Touch Panel Monitor: Monitors open/closed pressure pallets & can alarm on pressure relief to monitor emissions. Using L&J proprietary algorithms, it instantaneously sends back open relief alert as well as continually checking battery conditions. It can also be used for overfill protection to monitor MCG 109X Series Level Alarm Probes.
