Burkert 0253 User Manual
Operating Instructions T ype 0253
Voltage 12V or 24V
UL / UR valid with
class 2 power supply only
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.
Installation:
Before installing valve ensure that piping etc. is free of foreign
matter (metal fillings, seal materials, welding scale etc.). Installation as required but preferably 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.
Type 0253: PTFE tape is recommended for sealing ports.
Arrow on valve body indicates flow direction. Mounting is
accomplished by means of four M4 x 8 mm tapped holes
located on the valve underside.

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.).
