Model 96330I Internal Safety Shutoff and Operating Valve provides automatic quick acting shutoff of product flow in tanks and manifold lines. Extremely versatile, it can be mounted in a tank, or in line.

This valve is used most effectively for safety shutoff or operating valve in manifold lines. Its action is bidirectional with respect to flow and pressure, and its balanced piston design resists opening due to tanker
line pressure.
This valve is also ideally suited for “switch service” of LP-GAS, unhydrous ammonia, and similar products. Alternate materials of construction may be specified to meet other product requirements and operating temperatures in the range of -45° to +66°C.

Model 96330I Internal Safety Valve is designed to be held in a normally closed or open position by a springloaded 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 quickclosing
shutoff valve available.

A) The piston seal is insensitive to pressure
conditions, and the configuration provides ideal wiping and bearing action.

B) 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.
C) Easy Maintenance-New one piece seals greatly improve maintainability.
D) Redundant Springs-either capable of closing the valve.


Features & Benefits

• Positive Position Indicator
• Optional redundant springs provide added protection
• One piece seals greatly improve maintainability
• Fusible plugs automatically release operating pressure in case of fire
• 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 for on-off service with flows and pressure in either direction
• < 1.7 m3/h air leakage @ 7 Bar between tank and line. Bubble tight from product to hydraulic system
• Optional Redundant Springs
