The Shand & Jurs model 94070 Conservation
Closed Vent is constructed of Fiberglass
Reinforced Plastic (FRP). It has been designed
for superior corrosion resistance in oxidizing
environments. The 94070 is ideally suited for a
variety of tank storage and product conservation
applications. It is applicable for the chemical,
petroleum, petrochemical and waste treatment
industries. This conservation vent can be utilized
at the end of the line allowing vapors to escape
into the atmosphere. Its method of operation
allows pallets in the vent housing to open and
close permitting the vacuum or pressure relief
necessary to remain within permissible settings
thus avoiding damage to the tanks.
The weights are encapsulated lead. Available in
2” through 12” sizes with standard ANSI 125/150
lb or EN1092-1 PN10/16 flanges.
Construction options such as encapsulated
weights and extra corrosion barriers allow for
use in extremely corrosive environments such as
36% HCL.
The 94070 is easy to install and is completely
compatible with existing pipes, vents and
tank fittings. Its low initial cost and ease of
maintenance make the FRP Conservation Closed
Vent an attractive alternative to Stainless Steel,
Hastelloy and Monel construction.
