APPLICATION DESIGN
  • KRD excess pressure relief valves are used in smoke protection, ventilation and air conditioning systems to regulate the pressure difference between adjacent rooms.
  • The product meets the requirements of DSTU EN 121101-6:2016 "Smoke protection systems. Part 6: Technical requirements for pressure difference systems" (EN 12101-6:2005, IDT; EN 12101-6:2005/AC:2006, IDT).
  • KRD pressure control valve is made of galvanised steel with a rectangular cross-section.
  • The product is available with two flanges for direct connection to air ducts or with a single flange for installation in a wall.
  • The valve can only be mounted in a vertical position and all the axes of the working plates (blades) must be placed horizontally.
  • A spring mechanism located on the front side of the product acts as the adjustment element. Adjustment takes place during the commissioning of the smoke ventilation system and is performed directly by compressing the operating spring until the required trigger pressure is reached.
  • The pressure control range is 20-150 Pa.
  • There are no requirements for thermal conductivity or leakage class.
