The Shand & Jurs Model 94201 Emergency Vent and Manhole Cover with Expanda-Seal is an economical solution to present day emergency venting requirements. It is designed to relieve excessive internal pressure in liquid storage tanks while providing excellent protection against costly tank roof rupture repair. The Expanda-Seal™ design also decreases product leakage below actual set point. The standard design is available in 20` & 24` flange.

The Shand & Jurs Model 94210 Emergency Vent and Manhole Cover is an economical solution to emergency venting requirements where intermediate pressure settings are required. The design of Model 94210 employs a flexible diaphragm affording a tight seal between the pallet and the corrosion resistant seat below set pressure. This also assures low leakage. The diaphragm is intended for normal ambient temperature storage. Special diaphragms for tanks storing products other than oils and gasoline are available.

The Shand & Jurs Model 94221 Emergency Vent and Manhole Cover provides emergency relief of excessive internal pressure and vacuum beyond that provided by tank conservation vent requirements. This weight loaded vent utilizes Expanda-Seal diaphragms which provide tight seals between pallets and seats. Special diaphragm materials are available for vents subjected to severe low temperatures or used on tanks storing heated stock. Corrosion resistant pressure/vacuum seat is standard.

The Shand & Jurs Model 94225 Emergency Vent and Manhole Cover provides emergency relief of excessive internal pressure and vacuum beyond that provided by tank conservation vent requirements.

The Shand & Jurs Model 94510 Magnavent is a pressure operated emergency vent designed specifically to meet the NFPA ruling on venting requirements for small storage tanks. An economically designed and priced unit, the principle of operation is based on a unique magnetic latch.

The Shand & Jurs Model 94520 Emergency Vent provides emergency venting and manhole requirements, where intermediate pressure relief beyond that provided by tank conservation vents is required. This vent is not intended to meet requirements of explosion relief, but is designed to relieve excessive internal pressure. It is a economical solution to costly and dangerous tank roof rupture problems.

The 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.
