Product Description
  • The RYL Hydrobar Vario Upstream valve is a 100% hydraulically operated control valve that maintains the upstream pressure at a preset value regardless of variations in demand and, at the same time, it controls and regulates the minimum and maximum level of a tank. If the upstream pressure drops below the set point, upon opening, the valve will close to guarantee water supply to consumers in the upper zone of the network. The Hydrobar Vario Upstream valve is extremely important for stabilizing the piezometric line, containing unwanted overpressures and limiting excessive flow to the reservoir.
  • The valve is designed to reduce pressure loss, noise and damage related to cavitation. The RYL control valve is completely modular and can be used for a wide range of applications
  • Epoxy coating according to FBT technology, color blue RAL 5005.
  • Internal and external application with a minimum coating thickness of 250 μm.
  • Epoxy coating, approved for drinking water, electrostatically applied according to DIN 3476-1.

Information for sizing:

  • Avoid possible high points and sudden changes in slope on the piping between the valve and the level control pilot.
  • The AC (anti-cavitation) system is necessary for applications with static values above 7 bar, in this In this case, consult RYL for proper valve sizing.
