3630

Model 3630

Model 3630 constant flow regulator comes with a choice of an AISI 316 stainless steel or aluminum body. It is a sturdy, industrial constant flow regulator.

It is designed to provide a constant flow of liquids in applications where supply or backpressure varies and to provide a constant flow of gases in applications where backpressure varies. It is a membrane type differential pressure controller and is supplied with Model L variable area flow meter for flow rate indication and setting.

Typical applications are water purging for instruments, gas purging in Δp measurements and hydrostatic density measurements.
