Features
Self-acting pressure reducing valve for steam
This valve reduces the steam supply pressure to a defined outlet pressure and keeps it steady, even under downstream fluctuations . The valves needs no seperate energy source.
Operating features of direct acting pressure reducing valves
Pressure changes on the downstream side are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to keep the pressure on the downstream side at set pressure.
Wide range of pressure reduction
Due to carfefully selected springs an outstanding reduction ratio of 25:1 is achieved.
Diaphram free design
The valve operates with an O-ring sealing and a piston design. Due to this design, no daiphragm and no external sensing line is required.
Superb durability
Highly durable and carefully selected components, a 360° free rotating, conical plug and the lack of a sensitive diaphragm ensure outstanding lifetime of this valve.
Options available
- additional pressure gauges
- tailored connections for special applications
- softsealing for leakage class VI
Typical applications
Perfect for all applications with medium to high steam flow or high reduction. In particuliar power plants, chemical and petrochemical process applications, ships, food and beverage plants, and other similar installations of of compact steam equipment.
