The Shand & Jurs 94160 Pressure Relief Vent provides pressure relief for storage tanks and low pressure vessels. Utilizing a flange mounted design, this economical vent provides maximum flow capacity and high efficiency.
The improved vent uses a reduced number of standard components thus minimizing maintenance and replacement costs.
Standard materials of construction include aluminum, cast iron, steel and 316 stainless steel. This selection of materials is suitable for applications in corrosive and toxic product environments.
To ensure alignment and seating, the pressure pallet used is both peripheral and center stem guided. For added reliability and extended service, the diaphragm is “cushion seated” and constructed of FEP, contributing to high resistance to adhesion of ice and gum formation. Seat rings are field replaceable.
For additional protection, a weatherhood and a coarse mesh screen surrounding the entire valve prevent foreign matter from entering the valve.
A standard flanged base for sizes 2” thru 24” will fit 150 lb. ANSI FF/RF Flanges. Flanged base materials are aluminum, cast iron, cast steel, ductile iron and stainless steel. RF Flange is not available in aluminum.
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 .5 SCFH of air at 95% of the set point.
