Durabla 215jba4a3f Sanitary Check Valve 2.5 in 316L Ss

Product Description

The DURABLA 215jba4a3f is an inline spring-assisted sanitary check valve engineered to prevent flow reversal in hygienic and high-cleanliness piping systems. Built with a 316L stainless steel body and seat, this horizontal DSV-series valve is rated to 150 CWP and sized at 2.5 inches. The disc and seat are lapped to deliver positive shutoff. A Viton body seal and quick-release clamp allow fast access to internal components for inspection or service without specialized disassembly tools. Licensed plumbers and pipefitters working in food processing, pharmaceutical, or sanitary process piping will find this valve suited to demanding cleanliness code requirements.

This valve is configured for horizontal pipeline installations where a self-draining valve is required. The horizontal orientation allows the valve to drain freely when the line is depressurized, preventing pooling that could compromise sanitation. Spring-assisted operation ensures the disc returns to the closed position promptly when forward flow stops, guarding against backflow in process systems where contamination or pressure reversal poses a risk. Installations requiring vertical mounting or non-draining horizontal service are better served by the vertical DSV configuration.

Key Features

• 316L stainless steel body and seat for corrosion resistance in sanitary service
• Spring-assisted disc ensures positive closure and reliable backflow prevention
• Horizontal self-draining design suitable for hygiene-critical process lines
• Viton body seal provides elastomeric sealing compatible with a range of process fluids
• Quick-release clamp fastener allows fast internal access without full valve removal
• Lapped disc and seat surfaces deliver tight, repeatable shutoff

Compatibility

Designed as an OEM-style replacement or direct installation fitting for 2.5-inch sanitary process piping systems requiring a horizontal self-draining spring-assisted check valve.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber familiar with sanitary process piping standards. Depressurize and isolate the line completely before removing or installing the valve. Confirm flow direction arrow on the valve body is aligned with the intended process flow direction before securing the clamp. Follow applicable plumbing and process piping codes for your jurisdiction regarding sanitary fittings and clamp torque requirements.
