Burkert 0404 User Manual

Operating Instructions Type 0404

Voltage 12V or 24V

UL / UR valid with

class 2 power supply only

Design:

2-way solenoid valve, internally piloted, normally closed
(Circuit function A) or normally open (Circuit function B).

Seal Materials and Fluids handled:

See Table1.

Fluid and Ambient Temperature:
For Hazardous Locations Div. 1 (T4 rated)

Max. Ambient Temperature 104 °F (40 °C)
Max. Fluid Temperature 194 °F (90 °C)

For Hazardous Locations Div. 1 (T6 rated)

Max. Ambient Temperature 104 °F (40 °C)
Max. Fluid Temperature 140 °F (60 °C)

For Hazardous Locations Div. 2 and Ordinary Locations:

See Table1.

Pressure Range:

Minimum pressure differential between inlet and outlet port is
15 PSI.
Maximum inlet pressure see label on valve.

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.

Electrical Connection:

Ensure supply voltage/frequency corresponds with that on label.
Voltage tolerance is ± 10 %.
Available Electrical Connections see “Marking”.
Wiring diagram see above.

For this product to be considered UL-listed and CSA approved
for General Purpose and FM approved for Hazardous Locations
Division 2, it must be in conjunction with the type 2509 cable plug
connector (Electrically Operated Valves Parts, YSYI2).
The connector and gasket must be assembled to the valve with the
screw provided after the connection of the wire leads. This valve
and connector assembly is delivered together and is to be used as
one unit.

For valves to be used in Intrinsically Safe Applications the positive
pole is identified by a “+” on the pin or wire No. 1 has to be con­nected to the “+”.
See Control Drawing for the Rules of Interconnection.

Warning:

All valves to be used in Intrinsically Safe Applications must be
clearly marked as Intrinsically Safe Apparatus.

Trouble-Shooting:

Check port connections, minimum operating pressure differential
if required and supply voltage. Ensure pilot hole in piston is clear
and pilot bore in the valve outlet is not abstracted. If core does not
pull in, check for short circuit, coil burn-out or foreign matter im­peding core movement. A jammed or missing core causes the coil
to overheat in the case of AC supply.

Warning:

These products are designed to operate in a wide variety of ap­plications, it is the user’s responsibility to select a model that is
appropriate for the application. This product is designed to be
installed only by suitably qualified and trained personnel.
Specifications should not be exceeded under any circumstances.

The torque for the terminal screw on type 2509 is 0,5 Nm
(4,4 lbf-in.).
