PRODUCT DATA SHEET Designed for high efficiency & economy Provides maximum flow capacity Reduces maintenance and replacement costs Suitable for corrosive and toxic applications Standard flange base

Utilizing a flange mounted design, this economical vent provides maximum flow capacity and high efficiency. used is both peripheral and center stem guided.

Seat rings are field replaceable. The improved vent uses a reduced number of standard components thus minimizing maintenance and replacement costs.

To ensure alignment and seating, the pressure pallet For additional protection, a weatherhood and a coarse mesh screen surrounding the entire valve prevent foreign matter from entering the valve.

1 PRODUCT DATA SHEET Designed for high efficiency & economy Provides maximum flow capacity Reduces maintenance and replacement costs Suitable for corrosive and toxic applications Standard flange base for 3, 4, 6, 8,10, 12", 16, 20 and 24 to fit 150 lb. ANSI flanges The Shand & Jurs Model The Shand & Jurs Model 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. used is both peripheral and center stem guided. For added reliability and extended service, the diaphragm is "cushion seated" and constructed of FEP Teflon, contributing to high resistance to adhesion of ice and gum formation. Seat rings are field replaceable. The improved vent uses a reduced number of standard components thus minimizing maintenance and replacement costs. Standard materials of construction include aluminum, 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 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 3" thru 12" will fit 150 lb. ANSI flanges. Flanged base materials are aluminum and cast iron for 150 lb. flat face flange, and cast steel and stainless steel for 150 lb. raised face flange. Shand & Jurs Expanda-Seal option is available on all pressure pallet assemblies. This feature, shown in blue, significantly reduces leakage. The ballooning effect of the teflon diaphragm effectively seals the valve. The Expanda-Seal feature ensures less than.5 SCFH of leakage at 95% of the set point. an L&J Technologies Company sales@ljtechnologies.com ISO 9001 Certified 1
