What is the difference between a balancing valve, a globe valve, a DRV and a control valve?

- Dec 26, 2018 -

A balancing valve is a type of proportioning valve that forces flow within a system to stay as designed… a more colloquial name would be a “flow splitter”.

An example would be an excavator with two pistons on it’s main arm… flow split must be enforced as a safety feature… a balancing valve with a 50/50 split feeding each of the cylinders.. so if a gland has a total failure in one piston, pressure and flow are maintained to the other so there is not a catastrophic collapse.

A globe valve is a mechanical device that uses a conical seat and plug arrangement typically at a right angle to flow. the plug is moved by a threaded shaft. They are typically used to control flow as they are reasonably linear in their response… but should only be used in one flow direction.

A DRV, or Dual Regulated Valve is literally what it’s name says… it is an automatic valve that will regulate flow in both directions by reducing pressure to it’s set point.
