Vetus nipple set double locking block, control pump kit, for K30/140 locking block

Double locking block

This double check block must be installed if two steering pumps are used and the pumps do not have integrated check valves. Alternatively, you can use two steering pumps with a built-in HTPR double check valve. This block must also be used if an electro-hydraulic pump is installed when installing an autopilot and the built-in steering pumps do not have integrated check valves.

The connection kit must be ordered optionally and is not included with K30/140B.
