4/2 and 4/3 Plate Valves M/806
Port size: l" B.S.P.
Operating pressure: 1-10 bar
Cv. factor: 3.0
Operating temperature: -20°C* to +80°C.*Important: Referto leaflet F1.
These 4-port plate valves are very similar to the popularM/805 range of plate valves, the main difference beingthe fact the ports are t" B.S.P. The main working components of these valves are made of corrosion resistantmaterials.
By varying the angular movement of the lever a certainamount of flow regulation can be obtained on theM/806/107 and BM/806/1 07. The M/806/187 isfitted with a detent feature which gives a positivemid-position. The -/487 models are similar to the -/187model but are fitted wit h a positive latch mechanismto prevent accidental movement. The valves are sealedwhen in the mid-position. The valves are mounted bymeans of four tapped fixing holes in the bottom ofthe base.
M/806/107
The BM/806 valve has four ports which are all groupedon the under-side of the valve. Four fixing holes aretapped in one side ot the base as well as in the bottomof the base.

When the mark on the rotary lever is set against thefigure '2' the port connections ot the valve are as in thediagram on the tar left, Le., the inlet port '1' isconnected to the cylinder port '2' and the cylinder port'4' is connected to the exhaust port '3'. When in themid-position all the ports are isolated as shown in thecentre diagram. The diagram on the right shows theport connections when the mark is against the '4',Le., port '1' is connected to port '4' and port '2' isconnected to port '3'.
