Pressure Range:

Maximum inlet pressure see label on valve.

Installation:

Before installing valve ensure that piping etc. is free of foreign
matter (metal shavings, pipe sealing materials, welding scale
etc.). Installation as required but preferable with coil uppermost.
Installation in this position tends to prevent foreign matter
remaining in core tube (increased life). Do not put any loads on
coil unit.
PTFE tape is recommended for sealing ports. Mounting is
accomplished by means of four M4 x 8 mm tapped holes
located on the valve underside. Letters on valve body indicate
pressure port, exhaust and outlet of the valve.
