Product Details
Soft Start & Pressure Decay
These LF3000 Series fittings allow air pressure to gradually increase when a compressed air line is restarted after venting.
Pressure Decay Sensor
Produces a pneumatic end-of-stroke signal when the exhaust back pressure in the cylinder is no longer present.
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
Used to detect end-of-travel of a cylinder
Response time 3ms
