Pneumatic Control Valves from Dual Valves Australasia

Dual Valves Australasia introduces a new range of pneumatic control valves for general purpose control and safety applications.  

The pneumatic control valves are suitable for remote start/stop of flow, pressure relief, flow control, pressure control, level control and excess-flow shutdown applications.

Key elements of the control system:  

  • Flow, level, S.G or pressure transmitter with an analogue output of 4-20 mA
  • Analogue switch receiving the signal from the transmitter, to close or open a set of N/C or N/O contacts
  • 4/3 directional solenoid valve, activated by the analogue switch to determine the N.G.D valve’s control position  

The integrated actuator is a natural part of the N.G.D pneumatic valve and is ideal for plants or pump stations where a compressed air source can energise many valves.

Key advantages: 

  • Off-the-shelf standard variety of pneumatic valves, fittings and pneumatic components to enable control or safety applications
  • Cost-effective and reliable actuating and control system
  • Low pressure actuating and control system
