These are mounted to the supply port of a control valve or the common supply line to a number of control valves and will only control equipment downstream of that point. Function is indicated with a black coloured identification washer.

Soft Start & Pressure Decay

These LF3000 Series fittings allow air pressure to gradually increase when a compressed air line is restarted after venting.

When downstream pressure equals 2/3 of the supply pressure, full flow is automatically established
Fully adjustable to optimise air line pressurisation time
Soft start prevents shocks to system components which can occur when full working pressure is immediately introduced
