Valves type Z^®1B  are used as control elements in automatic controlled remote control systems. They are designed to control the intensity of flow of liquids, vapors  and gases. Due to a wide material range and various design versions, the valves are applied in many branches of industry: chemical, heat engineering and power, paper, food, metal manufacturing, mining etc.

• execution which are limiting the level of generated noise:
  - anti-cavitations plugs
  - anti-noise plates
  - anti-noise kits 
•  high shut-off tightness, V class as per IEC 534/4 
•  long lifetime and reliable service afforded by special surface treatment (burnishing, nitriding, stelltiting)
• cooperation with multi-spring pneumatic actuators type P1/R1. Possibility of changing the range of springs without additional parts.
• special execution:
  - with heating jacket
  - for liquid and gas fuels
  - for low temperature applications (liquid oxygen, liquid nitrogen)
  - for oxygen
  - for acid gases with H₂S
