Technologically advanced pilot operated pressure reducing valve for precise control of technological processes in steam systems.

1. Self-positioning and shock-absorbing spherical piston and special design of the pilot regulator ensure accurate pressure maintenance even under adverse operating conditions.

2. Most of the internal parts of the movement are made of stainless steel for a long service life.

3. Filters for pilot and main valves have wide surface area for longer service intervals.

4. Internal impulse line eliminates the need for external one.

5. COSR-16 dampers from DN65 and above have a built-in silencer.
