Product description

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.
