Burkert 0406 User Manual

Operating Instructions Type 0406

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:

Minimum pressure differential between inlet and outlet port is 14 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.

Marking (example):

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.).
