Horizontal-Vertical (H-V) Lumbar Valve System

H-V Lumbar System Updated

Each Horizontal-Vertical (H-V) lumbar valve system adjusts for changes in posture to maintain pressure at appropriate levels in the standing and recumbent positions. When the valve unit is horizontal, the spring-actuated, ball-in-cone inlet valve alone controls the lower pressure limit. When the valve unit is vertical, the gravity-actuated, ball-in-cone outlet valve combines with the inlet valve to control the higher pressure.

Key Feature:

Each valve unit is color-coded according to its combination of horizontal and vertical closing pressures for easy identification.
