ANSI fl ange 20 & 24 fl ange sizes also designed to fi t API 650 fl ange DIN sizes available Materials of construction include Aluminum, Steel & 316 Stainless Steel Limit Switches availableThe Shand & Jurs 94210 Emergency Vent and Manhole Cover is an economical solution to Emergency venting requirements where intermediate pressure settings are required. The design of Model 94210 employs a flexible diaphragm affording a tight seal between the pallet and the corrosion resistant seat below set pressure.

2 This also assures low leakage. The diaphragm is intended for normal ambient temperature storage. Special diaphragms for tanks storing products other than oils and gasoline are available. When set pressure is achieved, the pallet starts to lift. Flow effi ciency rises rapidly to approximately 60% of a perfect orifi ce at 40% excess of the set pressure. At higher overpressure the fl ow effi ciency approximates 75%. For tank venting or examination, the entire hinged Cover may be lifted open in a matter of seconds, offering clear passage through the unobstructed opening. Since no gasket replacement or unbolting is necessary, this vent eliminates the expensive manpower needed to put conventional Emergency vents back in operation. Pallet construction permits a wide variety of pressure settings. See specifi cations for various pressure settings of all vent design is available in 10 , 16 , 20 , 24 , 30 and 36 sizes.

3 The 10 , 16 , 20 , 24 , 30 and 36 vents have a fl at face fl ange which matches a 150 lb. ANSI fl ange. The 20 and 24 vents can be provided with fl at face fl anges to fi t API Roof manholes . Special construction types are also available. Expanda-Seal Shand & Jurs Expanda-Seal option is available on all pressure pallet assemblies. This feature signifi cantly reduces leakage. The ballooning effect of the Tefl on diaphragm effectively seals the valve. 94210 Emergency Vent & Manhole Cover ( hinged )Pressure Below Set PointApproaching Set PointSet Point ExceededEmergency Vent & Manhole Cover ( hinged )Rev: 94210 -3A2942105911 Butterfi eld Road Hillside, IL 60162 tel: (708) 236-6000 fax: (708) ISO 9001: 2008 Certifi edDimensions Specifi cations Standard Materials of Construction * Internal Clamp Ring is Steel on 16 and 20 Size.
