 Sequence Control Valve - Code 200
  Parker Conflow's Code 200 is a sequence control valve which switches on electrical equipment by detecting the movement of a conveyor belt in dust suppression applications.    
    Parker Conflow's Code 200 is a sequence control valve which activates electrical equipment by detecting the movement of a conveyor belt in dust suppression applications. It is a mechanical valve that does not require its own power supply. 
 Code 200 operates via a drive wheel, which is in frictional contact with the moving conveyor belt and requires no additional power supply. The rotating wheel generates hydraulic pressure to close a microswitch built in to the unit, which indicates to a control room whether the belt is stationery or moving.
 
 Markets:
 - Quarrying
 - Mining
 
 Features/Benefits:
 - Enables sequence control of associated conveyer belts and auxiliary equipment.
 - No power required for unit.
 - Still very effective at low belt speeds, down to 0.5 m/sec .
 - Can be adjusted to varying belt speeds.
 - Compact tried and tested design from CODE 100.
 - Can be positioned underneath belt to prevent damage.
 - Low maintenance.
 - All spare parts available to replace.
 
 Applications:
 - Belt Conveyors
