Model 3630.

The Kytola 3630 constant-flow regulator is a diaphragm-operated differential-pressure controller, also known as a self-operated regulating valve or constant-flow valve. It automatically maintains the required gas or liquid flow when pressure changes—for example, low liquid flows with varying supply and back pressures, or gas flows with varying back pressure.

Model 3630 is available with an AISI 316 stainless-steel or aluminum housing. It is normally combined with a Kytola model L variable-area flow meter.

Model 3630 has a rugged construction, installs vertically and is easy to maintain.

Typical applications include air and water purging of equipment, gas purging for differential-pressure measurement, and hydrostatic density measurement.

Maximum flow: water 1.5 L/min; air 60 NL/min at +20°C and 6 bar(g).
