700 Series valve

The 700 series basic hydraulic valve is a diaphragm-actuated, hydraulically-operated, globe valve in either the oblique (Y) or angle pattern design. This design ensures that cavitation is reduced and, pressure loss is up to 30% less than from other control valves. The perfected design 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 marks and applications.

The advantages of 700 Series valves:

  • Low pressure loss due to semi-straight flow
  • Protected diaphragm
  • Adjustable closing speed to prevent water hammer
  • Excellent cavitation resistance
  • Maintenance-friendly
  • Exceptional pressure control stability
  • Opens at low inlet pressure

The 700 Series valves come in 3 verities:

  • 700: The standard 700 Series
  • 700 EN: Full bore throughput for lower pressure loss
  • 700 ES: Anti-cavitation valve with greater cavitation resistance for conditions with greater pressure loss.

Models:

  • Sizes straight: 1½" - 48" DN40 - DN1200
  • Sizes (angled): 1½" - 18" DN50 - DN450
  • Sizes straight EN: 2" - 12" DN50 - DN300
  • Sizes straight ES: 1½" - 24" DN40 - DN600

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
