Product detail

Product code Reducing valves SRV2 - Spirax Sarco
Applications Steam Pressure Reducing Valve regulates the steam pressure downstream from the valve to a pre‑adjusted set point value.

Direct acting - Low capacity

 

The downstream pressure signal moves a set of bellows against an adjustable spring. Valve movement is proportional to downstream pressure. The greater the flow, the larger the offset.


For clean steam applications

 

Features & Benefits:

  • Extremely robust
  • Easy to adjust
  • Easy to maintain chamber is closed. The product can then flow from one line to the other.

Steam Reducing Station

 

Many industrial plants produce high-pressure steam for process work.  In many of these plants, there is excess steam capacity available that can be utilized for other purposes, such as space heating, water heating, etc.  Process steam is often generated at a higher pressure than can be used for the other purposes.  Whatever the needs for lower pressure steam, a pressure reducing station will be required.

 

A pressure reducing station is more than just a reducing valve fed off a steam main.  A properly designed and installed pressure reducing station takes into consideration velocity, good piping practices, and safety.
