Options Many options are available. The most requested

options are mentioned below.

Materials Regulators can be produced in higher graded materials

than stainless steel 316L.

Seals

Regulators can be equipped with FFKM + PTFE seals. Other compounds for higher or lower temperatures are

available.

NACE - MR 0175

All wetted parts of the regulators can be supplied according to NACE MR 0175, including Inconel X750

valvespring and a NACE report.

Spare parts Spare parts kit is available for the regulator. Mention the serial number in case you need spare parts for

existing regulators.

Dependency Character of the regulator is “dependency”.

The set-pressure will increase, when you have a decreasing inletpressure.

Dependency ratios are listed below.

• range 0-280 bar - 1:400

without pilot regulator

Dependency ratio is influenced by the mounted pilot regulator.

The balanced valve has a positive effect towards

dependency.

Flow The regulator has good flow performance over the

complete range. Ask for advice if this regulator is the best choice for your application.

Pilot regulator The regulator can be supplied with a mounted pilot

regulator. The pilot regulator provides the controlled pressure in dome.

External feedback The pilot regulator can be supplied with an external

feedback from the outlet of the main regulator, back to the pilot regulator. The external feedback improves the

performance of the regulator.

The external feedback option is available for design

pressures up to 50 bar.

Adjusting the regulator The regulator comes standard with two 1/4” NPT dome connections. The setpressure of the regulator

equals to the pressure in the dome.

Internals The internals of the regulator are important for the

performance. The different internals are mentioned below.

Diaphragm sensing

Diaphragm sensed for all ranges.

Rubber or plastic seated

Rubber seats for design pressure up to 50 bar. A rubber seat is less sensitive to dirt.

Plastic seats for design pressure above 50 bar.

PCTFE recommended and seals easy.

PEEK recommended for liquid and high temperatures.

Valvespring The valvespring gives high spring force to ensure seat-

tightness.

Gaugeports The regulator has standard two 1/4" NPT gaugeports

to measure the inlet and outletpressure.

On request it is possible to have additional gaugeports.

Gauges Regulators can be supplied with gauges.

Below ranges are available:

0-4 bar / 0-10 bar / 0-25 bar / 0-60 bar / 0-160 bar /

0-400 bar

• case diameter 63 mm

• internals ss 316

• bottom connection 1/4” NPT

Mounting The regulator can be mounted in every position

(horizontal / vertical).

For regulators installed outdoors, make sure that rain cannot enter the springhousing or mount it drainable.
