Description

Features

Pressure reducing valves for liquids and gases

The model REA20 is a direct acting pressure reducinf valve designed for use of compressible media, such as air and various gasses and for incompressible media such as water, oil and others.

Due to carefully selected springs a wide range of pressure applications is available.

As option the valve can be equipped with a pressure gauge on the valve body.

Operating features of direct acting pressure reducing valves

Pressure changes on the secondary side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the secondary side at a set level.

Maximum pressure reduction ratio 25:1

Uses

Perfect for cleaning devices, foodstuff devices, and other forms of compact steam equipment.
