Insta-Valve Plus

Underground valve insertion support for water utility control and service isolation.

Valve Installation

Add control points without replacing long pipe runs.

Insta-Valve Plus installations help utilities add valve access at targeted locations in underground water systems. Coast Underground supports excavation, pipe exposure, trench preparation, and field installation work around existing utility infrastructure.

The system is designed around a full unobstructed waterway, resilient seat sealing wedge, triple O-ring seal, heavy duty flange, and stainless or low alloy hardware.
