Mark 70 Series Pneumatic Diaphragm Control Valve

Brand: Jordan Valve

The Mark 70 Series is a line of pneumatically-operated diaphragm control valves that combine multiple spring actuators with the precision of the sliding gate seat for closer control and greater accuracy.

A side or top-mounted positioner is available to overcome the normal hysteresis for a control valve and actuator and to ensure that the valve stem position is always directly proportional to the control valve command signal.
Features
  • Totally enclosed multi-spring actuator – Minimizes deadband and is field reversible without the use of special tools or additional parts
  • Compact design and simple construction allows fast installation and easy maintenance
  • Stem packing is four times deeper than stem travel for greater protection against leakage
  • Sliding gate seats provide straight-through flow for reduced turbulence and quiet operation
  • Short stroke for fast response and accurate regulation
  • Easily interchangeable CV’s
  • Tight shutoff
