Flow Control Valve – LowFlow Mark 708HP/HPA Series

  • The LowFlow Mark 708HP/HPA flow control valve series was developed to provide accurate control on high pressure fractional flow applications.
  • Complete line of pneumatic and electrically actuated control valves designed to enhance performance to ensure precision control on your most critical high pressure micro flow applications.
  • LowFlow Mark 708 HP offers models with maximum inlet pressure up to 8000 psi / 552 bar. Mark 708HPA has models with max inlet pressure up to 12,000 psi / 825 bar.
  • This rugged, compact control valve is suitable for variety of industrial and research applications.
  • Linear and equal percentage flow characteristics are available with Cv’s ranging from 0.05 (0.04 Kv) to 1.25 (1.1 Kv).

Key features

  • Union style body connection – provides solid construction and secure connection
  • Rolling diaphragm – ensures that the effective diaphragm area remains relatively constant, regardless of stem position. This increases accuracy of the actuator when positioning the valve by ensuring a linear response to input signal changes.
  • Mechanically loaded PTFE Chevron heavy duty V ring packing
  • Metal C ring gasket provides excellent sealing without exposing the bonnet threads to the media
  • Standard with side mount positioner

Application areas

  • Hydrogen fuel cell test systems
  • Hydrogen fueling, storage and manufacturing systems
