HyDrive Single Copper Lock Valve Kit

HyDrive Single Copper Lock Valve Kit features the
331C lock valve, a single double acting lock valve designed to
prevent load motoring the helm unit. This should be used where the
autopilot has a lock valve of it’s own, or to eliminate feedback
from a highly active rudder. These valves are available with
various fittings and kits to make dual station installations very
simple.
