FAQ

What is the difference between a unidirectional and a bidirectional flow regulator?

A unidirectional regulator, like this 7110 21 21 model, controls flow in only one direction while allowing free flow in the opposite direction. This is ideal for controlling the speed of a cylinder’s extension or retraction stroke independently. A bidirectional regulator restricts flow equally in both directions.

What does "meter-out" or "meter-in" mean for this valve?

This valve can be used in either configuration. "Meter-out" means it controls the speed by restricting the exhaust air leaving the cylinder, which generally provides smoother, more stable control. "Meter-in" restricts the air entering the cylinder. The optimal configuration depends on the specific application and load.

Is any specific thread sealant required for the G1/2 BSPP threads?

Yes, for BSPP (G) parallel threads, a sealing washer or O-ring is typically required on the male port to create a proper seal against the mating surface. While some pre-applied sealants can be used, relying on the mechanical seal of a washer is best practice for these parallel threads to ensure a leak-free connection up to the rated pressure.
