Downstream Series-600 – Features

  • Reduces higher inlet pressure to a constant lower Outlet pressure.
  • Outlet pressure is accurate over wide range of flow.
  • Pilot-operated main valve is not subject to pressure fall off Characteristic of direct-acting PRV’s.
  • Outlet pressure is adjustable over complete range of control spring.

Upstream Series-700 – Design Features

  • Glandless Construction: – Where positive Zero gland packing is required, the design scores over conventional solutions such as bellow seals etc. as the gland itself is eliminated.
  • Wide range of body sizes and trim sizes to satisfy varied flow requirements.
  • Tight sensitively and stability of controlled pressure.
  • Provides excellent tight shut off capability over long working life.
  • Compact design with minimum number of moving parts.
  • Simple resetting.

Upstream Series-700 – Quality And Performance Guarantee

  • Produced with Quality Systems accredited to ISO 9001: 2008 by Bureau Veritas.
  • Full material certification available for all major component Parts.
  • Full guarantee on design and Performance.
  • All testing are performed to the requirements of ANSI B16.34.
