Description

Features

Pressure reducing valves for steam

These are automatic valves that reduce the steam supply pressure to the certified pressure for the device in use, and keep it steady.

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.
