A dual non-return valve block is used to provide a junction for hydraulic hoses to connect a second helm station or autopilot electro-hydraulic pump. This should only be used if the pumps do not have built-in non-return valve blocks: if they do, tee-pieces should be used.
The valve block has six 1/4" BSP female connectors, ready for a connection kit for either 8mm or 10mm hose, which should be ordered separately.
Hose support sleeves should be ordered separately unless flare connectors are being used.
