Title UBB BPM ACCESSORIES UBAS HP
Description

Direct operated pressure reducing / relief valve
  • Direct action Regulator, reduction, and back pressure from DN 25 to DN 500
  • Single or double seat
  • Metal or sof seat
  • Special solutions : Cage trim
  • ARAMCO APPROVED SINCE 2015

Warning
The MyStabilizer is provided to create an adequate pressure after the valve to prevent cavitation. In this way is possible to avoid damage of the valve. It becomes especially important in modulating systems and when there is a variation of the flowrate because it can follow the variation and it can create the right back pressure
Features:
  • wafer and flanged design
  • good rangeability
  • easy installation and low maintenance
  • carbon steel and stainless steel. Other materials on request

The Fixed Multi-Holes Disc  is provided  to create an adequate pressure after the valve to prevent cavitation. In this way is possible to avoid damage of the valve . It is very easy to install and it don’t need maintenance.

Features:
