800 Series Valve

The 800 series piston actuated valves are hydraulically operated globe valves in either the standard oblique (Y) or angle pattern design. Using this piston means that no diaphragm is required and the unit remains extremely reliable, even under high pressure. The design ensures that cavitation is reduced and, pressure loss is up to 30% less than from other control valves. The valve meets the requirements for drinking water distribution on an urban scale and in buildings, wastewater, fire protection systems, industry and water flows in general. The valve comprises two major components: the body seat assembly and the actuator assembly. The actuator assembly is unitized and is removable from the body as an integral unit. It consists of both an upper and a lower control chamber. Due to this design the valve is maintenance friendly and can be done without removing the unit from the installation. We can advise you based on the required flow rate, functions, quality approvals and applications.

The advantages of 800 Series valves:

  • Low pressure loss due to semi-straight flow
  • Diaphragm free technology
  • Adjustable closing speed to counteract water hammer
  • High maximum work pressure
  • Maintenance-friendly
  • Exceptional pressure control stability
  • Opens at low inlet pressure

Functions:

  • Both hydraulic and electrical opening and closing
  • Pressure reducing
  • Pressure sustaining
  • Flow limiting
  • Level control for reservoirs
  • Check valve
  • Pump control valve
  • Water hammer arrestor

Options:

  • Various solenoids
  • N.O. version-electrically closing
  • Various materials
  • Combination of functions
  • Various flange standards
  • Epoxy coating
  • Valve position indicator
  • Anti-cavitation cage
