Model 96330 Internal Safety Shutoff and Operating Valve provides automatic quick acting shutoff of product flow in tanks and manifold lines. This valve is used most effectively for 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 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 -10° to +66°C.

The Model 96330 Internal Safefy Valve is designed to be held in a n arm ally closed or open position by a spring-loaded balanced type piston. The valve checks closed in either direction when operating pressure is

Several unique items are incorporated prov iding the most reliable quick-closing shutoff valve available. AJ The piston seal is sensitive to pressure differential to seal fluid in either direction.

Model 96330 is sew adjusting to pressure conditions. and the configuration provides ideal wiping and bearing action.
BJ The plunger seal is spring -loaded toad just to wear and thermal conditions.
CJ The valve ring is self-aligning to assure proper seating act ion in a design that permits greater seating thrust than available in conventional flat scaling systems. Valve ring and seating design also incorporates a sew-cleaning function.
