A wide range of valve bodies
 
ISTEC thermostatic valves need no external power, they maintain the room temperature by controlling the flow of hot water or steam.

The valvebody is made of non­ corrosive nickel-plated bronze/brass.

The valve stem and spring are made of stainless steel. The valve disc and ”O”-ring are made of high temperature EPDM.

The valves are available in straight, angle and horizontal angle patterns.

The ISTEC valve cartridge can be exchanged while valves are instal­led and the system is under pressure by using the specially designed ”demo-bloc” tool.

Applications

For one and two pipe central heating systems. Suitable for both forced hot water and steam applications.

What are the advantages of ISTEC valve bodies?

  • special valve body design
  • prevents flow noises and provides optimized CV values.
  • the ”O”-ring gland is replaceable under system pressure.
  • the valve cartridge can be re­placed witout draining the system by means of ”Demo-bloc”-tool.
