Mechanical Gauge Hatch Series
For tank farm engineers, terminal operators, and inspection planners, the Shand & Jurs 95000 Series provides a graduated family of manual tank access closures, letting specifying engineers match the hatch to the tank’s operating pressure and vapor control requirements rather than over-buying or under-specifying a single universal design.
Unlike approaches that install one pressure-compatible hatch on every tank regardless of service, the 95000 Series spans from open-access thief hatches (95004, 95010, 95011, 95014) through pressure-compatible clamped closures (95021, 95050), so containment level and resealing consistency are matched to the tank’s actual envelope.
All models mount to threaded or flanged nozzles and allow sampling, temperature measurement, and manual gauging without disturbing conservation vent operation when properly selected. Body material options across the series include aluminum, carbon steel, 316 stainless steel, and bronze.
Models 95021 and 95050 have their own dedicated datasheets with full specification detail. Model selection directly determines resealing consistency, allowable internal pressure, and the degree of vapor release permitted during gauging events.
Series spans open thief hatches through pressure-compatible clamped covers, letting specifying engineers buy only the containment level the tank actually requires.
Flexible and metal-seat sealing options across the series maintain stable tank pressure behavior between gauging events at the selected containment level.
Supplemental venting capability ranges from none to 3.5 oz/in² across the series, supporting secondary relief where tank architecture requires it.
Clamped configurations (95021, 95050) maintain closure on pressure-controlled tanks where open thief hatches would leak continuously during normal operation.
Aluminum, carbon steel, 316 stainless steel, and bronze bodies with model-dependent hardware selections match corrosion, spark, and product-compatibility requirements.
Threaded or ANSI Class 150 flanged connections across the series support existing tank nozzle patterns without requiring nozzle modification.

Model selection is driven by the tank’s operating pressure and required vapor containment. Open thief hatches (95004, 95010, 95011, 95014) suit atmospheric tanks where minor vapor release during access is acceptable; clamped pressure-compatible models (95021, 95050) suit pressure-controlled or emissions-critical tanks where resealing consistency matters. Cognesense applications support can assist with selection.
Models 95021 and 95050 have dedicated datasheets with full specification detail. The 95000 Series datasheet describes the family-level selection logic and shared features; model-specific performance data for the pressure-compatible variants lives in the individual datasheets.
Body material options across the series include aluminum, carbon steel, 316 stainless steel, and bronze. Soft goods and hardware selections are model-dependent and chosen to match stored product, corrosion service, and any spark-reduction requirements for classified areas.
Yes. ATEX configurations are available across the series for installation in classified areas. Locking provisions and S-hook / thermometer supports are also available family-wide to match site-specific gauging practices and security requirements.
All 95000 Series models mount to threaded or ANSI Class 150 flanged tank nozzles, supporting common existing tank nozzle patterns without nozzle modification. Specific sizes and connection types vary by model.
Certain 95000 Series models incorporate a supplemental venting function, providing a secondary relief path during abnormal pressure rise. Capability ranges from none to 3.5 oz/in² depending on the model. Supplemental venting supplements, rather than replaces, a primary conservation vent or P/V valve.
With over a century of tank-safety heritage inside Cognesense, the Shand & Jurs 95000 Series is chosen when tank farms need graduated access closures matched to each tank’s actual operating envelope rather than a single universal hatch. The series spans open thief hatches through pressure-compatible clamped covers, letting specifying engineers align containment level, resealing consistency, and vapor release against the real tank requirements. Across petroleum, chemical, and low-pressure storage, the 95000 Series is trusted wherever you need to measure, monitor, and protect what matters most.
