96330I Internal Safety Shutoff & Operating Valve w/ Integral Position Indicator

The Shand & Jurs 96330I Internal Safety Shutoff and Operating Valve provides automatic, foolproof, quick acting shutoff, of product flow in tanks and manifold lines. Extremely versatile, it can be mounted in the tank, or in line.

This valve is used most effectively as a safety shutoff or operating valve in manifold lines. Its action is bi-directional with respect to flow and pressure, and its balanced piston design resists opening due to tank or line pressure.

This valve also is ideally suited for “switch service” of LP-GAS, anhydrous ammonia and similar products. Alternate materials of construction may be specified to meet other product requirements and operating temperatures in the range of -50° to +150°F.

The 96330I Internal Safety Valve is designed to be held in a normally closed or open position by a spring-loaded balanced type piston and seat ring assembly. The valve closes when operating pressure is removed.

Several unique items are incorporated, thus providing the most reliable quick-closing shutoff valve available.

  1. The piston seal is sensitive to pressure conditions, and the configuration provides ideal wiping and bearing action.
  2. A visual indicator provides a continuous positive indication of valve position. The indicator is physically attached to the actual valve mechanism giving a true indication of valve position.
  3. Easy Maintenance-New one piece seals greatly improve maintainability.
  4. Optional redundant springs – either capable of closing the valve.


  • Positive Position Indicator
  • Optional Redundant Duel Springs provide added protection
  • One piece self-adjusting seals greatly improve maintainability
  • Fusible plugs automatically release operating pressure when temperature exceeds its melting point
  • Fail safe under all conditions, unaffected by tank or line pressure
  • Standard valve is adaptable to ambient fluid products such as
    LP-Gas and/or Ammonia
  • Efficient as an operational valve or on-off service with flows and pressure in either direction
  • Maximum 1.0 SCFM air leakage @ 100 psig between tank and line. Bubble tight from product to hydraulic system
