Direct acting pressure relief valve with shock absorbing piston
The technologically advanced pressure reducing valve with integrated condensate separator and integrated steam trap provides precise pressure control and steam preparation for increased efficiency.
- Saving space during installation, simplifying the piping and maintenance work.
- The self-positioning and shock-absorbing spherical piston and the special design of the pilot regulator ensure accurate pressure maintenance even under adverse operating conditions.
- An integral cyclone separator with 98% efficiency and a free-float steam trap ensure high outlet steam quality.
- Most of the internal parts of the movement are made of stainless steel for a long service life.
- Pilot and main filters have a wide surface area for longer service intervals.
- The internal impulse line eliminates the need for the external one.
- COS-16 dampers from DN65 and above have a built-in silencer.
