Series MTDA units are flow dividing valves that operate automatically. They are intended for use with hydraulic fluids. They divide a flow, the total rate of which may be varied, up to 4 part-flows. When flow passes through a valve in the opposite direction, the part-flows are combined into one single flow (added).

The dividing and combining functions are largely independent of the pressures of the divided flows and of the fluid viscosity.

• These valves do not require maintenance. This lowers costs and reduces the risk of a system failure.
• Flows can be split or merged with accuracy (divide/combine functions).
• The flow division ratio can be altered to suit customer requirements.
• Options:
  - end-of-stroke equalisation
  - make-up valves
  - check valves
  - pressure-relief valves
