Burkert Type 0290 - Manual

Operating Instructions Type 0290
Design:
2-way solenoid valve, direct acting, normally closed (Circuit
function A).
Seal Materials and Fluids handled:
See Table.
Fluid and Ambient Temperature:
See Table.
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 filings, 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 matters.
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.
