HP320

Line pressure regulator

single stage diaphragm regulator for a high outlet pressure up to 200 bar

The line pressure regulator HP 320 is a single stage pressure regulator, brass nickel and matt chrome plated or stainless steel 1.4404 electro polished.

It is designed as a diaphragm pressure regulator and especially made for high outlet pressure.

The HP 320 reduces the pressure of com- pressed gases or fluids to a maximum outlet pressure of 200 bar.

It functions according to the principle guiding the equilibrium of forces between the set spring force and the outlet pressure.

Especially for gases with high requirements on purity up to 6.0 and for laboratories and analytics. In case of our special cleaning method the cylinder pressure regulator is ECD capable.

The stainless steel version with viton elasto- mers allows the usage of aggressive gases.

We recommend to prefix a fine filter with max. 40 μ at the inlet and an installation of suitable safety valves to protect downstream equipment from improper high pressures.

To identify the correct order code for your HP320

Start with "HP320-", then add the appropriate number options from columns A, B, C, D & E in the table below followed by the gas to be used.
