    Product Description

    The A6 Pressure Relief Valve has become a firm favourite with many manufacturers of leisure liferafts, RIBs and river rafts around the world.  It is ideal for any use where compact and reliable valves are critical, for example, on commercial & military inflatable boats. The opening and closing pressures are accurately pre-set and repeatable.

    A filter cap is available for use in environments where contamination is possible e.g. river rafts. This prevents contamination without affecting the pressure relief function.

    A range of pressure settings is available (see selection chart). The valves are marked with the date and pressure setting.

    The valve is available in grey, black or white. We can provide a black or red plug where a secondary seal is required, for example in liferaft applications.  Please note that when the plug is in place, the valve does NOT function as a pressure relief valve.

    It is also available as a non-return valve only with a nominal opening pressure of 0.29psi (0.02bar).

    A6 Filter Cap

    • For use in environments where contamination is possible e.g. river rafts.
    • Ultrafine mesh prevents contamination without affecting the pressure relief function.

    service tools

    A6 Valve Plug

    • Provides an effective secondary seal on the valve. This is required for some life raft approvals. This cap can also be used to prevent air loss through the pressure relief valve when an inflatable chamber is experiencing heavy impacts in rough seas, causing pressure spikes.
    • Available in Black or Red.
    • Highly resistant to Ozone, oil and other contaminants.
    • Please note that when the plug is in place, the valve does NOT function as a pressure relief valve.
