Burkert 5420 User Manual
Operating Instructions T ype 5420
Voltage 12V or 24V
UL / UR valid with
class 2 power supply only
Design:
4-way solenoid valve, internally piloted, P connected to port B
and R connected to port A when deenergized.
Seal Materials and Fluids handled:
See Tabl e 1.
Fluid and Ambient Temperature:
For Hazardous Locations Div. 1 (T4 rated)
Max. Ambient Temperature 104 °F (40 °C)
Max. Fluid Temperature 140 °F (60 °C)
The UL-listed valve for Hazardous Locations is suitable for the
fluids air, inert gas, water and gasoline.
For Hazardous Locations Div. 1 (T6 rated)
Max. Ambient Temperature 104 °F (40 °C)
Max. Fluid Temperature 140 °F (60 °C)
For Intrinsically Safe Apparatus for use in Class I, II and III,
Division 1 Hazardous Locations.
Max. Ambient Temperature 140 °F (60 °C)
Max. Fluid Temperature 140 °F (60 °C)
For Hazardous Locations Div. 2 and Ordinary Locations:
See Table 1.
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 upper most.
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.

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.).
