Blain 3/4" R10-S Rupture Valve Governor for Concord Savaria Lifts

Blain R10-S and R10-PS 3/4 inch overspeed rupture valve assembly replaces legacy 207178 in select Concord Savaria Infinity, Orion, and PAL units. Provide the lift serial number prior to ordering to confirm fit and function.

This overspeed and pipe rupture valve assembly mounts in any orientation directly at the cylinder inlet. It detects a pressure drop in the main cylinder line or excessive downward speed and closes to bring the car to a smooth stop with deceleration held under 1 g as a built-in, non-adjustable feature. Closing flow is field-adjustable via the top screw to match system requirements. Standard and optional configurations support the R10-S and R10-PS designations commonly used in searches. Compatible with select Concord Savaria Infinity, Orion, and PAL lifts where the legacy part number 207178 was original.
