Description
The Shand & Jurs 94130 Pressure Relief Vent is designed to provide pressure relief with high efficiency, maximum flow capacity and minimum leakage.
The easily serviceable configuration and light weight 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.
For dependable performance, Shand & Jurs Pressure Relief Vents utilize pressure pallets that are both peripherally and center stem guided.
The standard diaphragm is “Air Cushion Seated” and constructed of teflon for high resistance to adhesion of ice and gum formation.
A range of sizes and configurations, such as closed vent hood and flame snuffers are available. Standard pressure setting is 0.5 oz/in2.
Expanda-Seal
Shand & Jurs “Expanda-Seal” option is available on all pressure pallet assemblies. This feature significantly reduces leakage.
The ballooning effect of the Teflon diaphragm effectively seals the valve.
The “Expanda-Seal” feature ensures less than 0.5 SCFH of air at 95% of the set point.
