Flow Switch – VH0 Range
The Sika VH0 flow switch is similar in construction to the Sika VHS range but uses a micro switch in place of the reed switch which enables the VH0 to switch at much greater currents and therefore makes it ideal for more demanding electrical applications without the need for a relay interface.
The solid construction consists of a nickel plated brass switching body coupled to a brass tee piece with a stainless steel paddle assembly and is available in sizes from G3/8″ up to G2″ with decreasing switch points from 4 to 83 lpm (see data sheet for more detail).
Please note that the VH0 is fitted with a 5A SPDT micro switch and can therefore be wired as normally open or normally closed.
