The 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.
Available in 2"- 12" sizes, this vent is all weather for all materials and services. Pressure ranges are from 1-15 psi for 2"-10" sizes and 1-10 psi for 12" sizes. Flange connections match ANSI 150 lb. raised face or flat face for cast iron, steel and stainless steel construction. Aluminum construction comes in ANSI 150 lb. flat face flange only. Open vent body and seat material is the same except for steel which has a SS overlay seat. Closed vent model can either have Aluminum or SS seat.
An Expanda-Seal is available on the pressure pallet to assure minimal leakage up to 95% of set pressure.
One of the most important features which should be noted in the Model 94140 design is the variety of construction materials available. A wide range of highly corrosive and toxic products common to the petroleum, petro-chemical and chemical industries, require that a pressure vent be able to withstand this environment and still function reliably. For few instances where our standard materials may not be suitable, optional materials are readily available.
Standard materials offered are aluminum, cast iron, cast steel and 316 stainless steel. Standard seats are aluminum and 316 stainless steel.
