DP Series
DP Series control valve is used to control temperature, pressure and level of the fluid.
It is used where relatively small capacity is required and provides various flow characteristics depending on the shape of the plug.

FEATURES

  • Cage retained seat design is adopted. There are no internal threaded parts, and no special tool is required for replacement of the seats.
  • Lock nut connects the bonnet and the actuator. Lock nut connection allows quick assembly and disassembly of the valves, and the design also allows the actuator to be oriented in any direction (360 degrees) in relationt o the body.
  • Handwheel and positioner are provided as an option. Any other Accessories such as Air Filter Regulator, I/P Transducer, Pressure/Temperature Transmitter, Solenoid Valve and Limit Switch can be proviede if required.
