The Andair check valve is available in two types. The first is a complete closure valve. It allows fluid to pass in one direction whilst preventing it flowing in the reverse direction. Arrows on the outside of the body indicate the flow direction. The valve is machined from L168 Aluminium, then anodised for greater protection. To connect to the valve a range of fittings are available.
The second has a reverse flow bleed facility. Here the internal shuttle has been drilled with two small holes. This allows for bleed back to occur. This particular valve is useful in the vent line of a fuel system where allowance for fuel expansion is necessary.
The internal shuttle and spring are extremely light giving a cracking pressure of between 0.4-0.7 PSI.
As standard, both valves have AN-6 fittings machined on each end, but valves with hose connectors are available. See 301465 and 303151 .
