Sliding Gate Control Valve for High Flow, Higher Cv's (Kv's)

The Mark 701/702 high flow sliding gate control valve provides higher Cvs (Kvs) without going to a larger valve, straight through flow and ease of maintenance. 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 & Benefits
  • High flow and super high flow
  • Shorter stroke than a globe or plug-style valve – faster response, longer packing and seat life, stem packing is four times deeper than stem travel for greater protection against leakage, smaller & lighter weight than globe-style valves
  • Straight thru flow – less turbulence, erosion and noise, fewer spare parts, self-cleaning seats, no gaskets or o-rings
  • Ease of maintenance – interchangeable seats and Cv’s
