Product Description
  • The RYL Hydrobar Altimetric valves are a 100% hydraulically operated control valve which maintains the constant level of a reservoir and a water tower, regardless of upstream pressure variations. Level control with modulation ensures smooth regulation and the absence of water hammer, as the valve will react proportionally to variations in demand. Normally equipped with visual position indicators, body made of ductile iron with epoxy coating and internal parts of stainless steel.
  • 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.
  • Compliance with standards : Tested according to EN 12266. Face-to-face dimensions ISO 5752-1. 
  • Approval: ACS (Certificate of Health Conformity). 


Information for sizing:

  • Upstream, downstream pressure and flow rate are necessary for correct sizing.
  • The AC anti-cavitation device is recommended for resistance against cavitation and precise regulation in low flow cases.
  • A minimum length of 3 DN in upstream of the valve is recommended for better accuracy.


Pilot adjustment ranges Upstream:

  • Blue spring: from 0.7 to 7 bars.
  • Red spring: from 1.5 to 15 bars.
  • Higher values up to 25 bars on request.
  • Values below 0.7 bars available with high sensitivity drivers.
