94020 Conservation Vent (Pressure & Vacuum)

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.

A variety of construction materials are available as part of the standard design which are ideally suited for highly corrosive and toxic product applications.

Aluminum, 316 Stainless Steel or Carbon Steel body vents comes standard with integral seats or optional replaceable seats. Cast Iron and Ductile Iron bodies only with 316 SS replaceable seats.

The standard FEP diaphragm is “Air Cushion Seated” for high resistance to adhesion of ice and gum formation thus assuring protection against pallet sticking to the seating surface.

The body is self-draining towards the inlet which 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.

Conservation Vents are available in a full range of sizes and configurations, such as open vent, closed vent (pipe-away), cryogenic hoods and flame snuffers.

Standard pressure and vacuum settings are 0.5 oz/in2. The 94020 Conservation Vent is available with optional pressure and vacuum limit switches and visual indicators.

Shand & Jurs “Expanda-Seal” option is available on all pressure pallet assemblies. This feature significantly reduces leakage. The ballooning effect of the FEP Diaphragm effectively seals the valve.

The “Expanda-Seal” feature ensures less than 0.5 SCFH of air at 95% of the set point.
