Burkert Type 0407 - Manual

Operating Instructions Type 0407
Design:
2-way solenoid valve, internally piloted, normally closed
(Circuit function A).
Seal Materials and Fluids handled:
See Table1.
Fluid and Ambient Temperature:
See Table 1.
Pressure Range:
Maximum inlet pressure see label on valve.
A pressure differential between inlet port and outlet port is not
required.
Installation:
Before installing valve ensure that piping etc. is free of foreign
matter (metal fillings, seal material, welding scale etc.). PTFE
tape is recommended for sealing ports. Arrow on valve body
gives flow direction. Installation as required but preferable
with coil uppermost. Installation in this position tends to
prevent foreign matter remaining in pilot valve (increased
life). A strainer upstream of valve, protects against effects of
foreign matter. Do not put any loads on coil unit. Pipework
should be supported such that valve body is not under strain.
Do not allow a pipe-end or sealing material to block the pilot
bore within the valve outlet. Inlet and outlet of valve must be
fullbore and pipework unrestricted.
