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 light weight construction reduces maintenance and installation costs.
Standard materials of construction are low copper aluminum, cast iron, ductile iron, cast steel and 316 stainless steel for body materials. Aluminum, stainless steel and steel body vents come standard with integral seats and have optional replaceable seats. Cast iron and ductile iron bodies come with replaceable seats as standard design. Replaceable seats are made of corrosion resistant molded thermosetting phenolic, Teflon, aluminum, 316 stainless steel or stainless steel Teflon coated and are easily replaced.
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 blowdown.
Conservation Vents are available in a full range of sizes and configurations, such as closed vent hoods (pipe-away), cryogenic hoods and flame snuffers. Standard pressure and vacuum settings are ½ oz./sq. in. The Shand & Jurs Model 94020 Conservation Vent is available with optional pressure and vacuum limit switches and visual indicators.
