4 mm Flow Control Regulator

The Legris 7660 04 19 regulates pneumatic flow with a 4 mm push-to-connect inlet and an M5 x 0.8 outlet. It suits automation engineers and maintenance technicians who need precise speed control on compact actuators.

Thermals, noise and power draw

The valve body is rated for 145 psi maximum pressure and operates between 14.5 and 145 psi. Maximum media temperature is 158 degrees F, and the all-HAWA construction adds no electrical load or audible noise.

Upgrade context

This regulator replaces fixed orifices or non-adjustable fittings when 360-degree adjustment resolution is required. It is not suited for circuits exceeding the stated pressure or temperature limits, nor for installations needing larger port sizes.

Questions about this item

How do I install the Legris 7660 04 19 flow control regulator and what step is often missed?

Push the 4mm tube firmly into the inlet port until it seats, then thread the M5 x 0.8 outlet into the mating port; the step often missed is verifying the collet has gripped by pulling gently on the tube before pressurising.

What maintenance or replacement will the Legris 7660 04 19 need over time?

Inspect the push-to-connect seal and M5 threads periodically; replace the unit if leakage appears at the 4mm connection or if the adjustment knob no longer holds its setting within the 14.5 to 145 psi range.

What is the first limit reached on the Legris 7660 04 19 during sustained operation?

The 158 Degrees F maximum temperature rating is typically the first limit encountered under continuous cycling, as pressure stays within the 145 psi ceiling while heat can accumulate faster.
