Burkert Type 0256 - Plunger Solenoid Valve

The Burkert Type 0256 plunger solenoid valve is a direct-acting valve that can be used in multiple ways, like fluid control, pressure regulation, and automation systems. The valve has stainless steel or brass bodies for various connections and orifice sizes. Also, it has a block-screwed coil system (the coil is fixed directly onto the valve body using a threaded connection, providing a compact and integrated assembly for efficient operation). It is available in sizes up to DN 12.

Is Burkert Type 0256 - plunger solenoid valve the right choice for you?

The valve may be the right choice for the application if:

• The application requires a 100% duty cycle
• The valve is used in an atmosphere with ignition risks
• The application involves high vibration or dynamic environments.

Material

• Seal: NBR, FKM, others on request
• Body: Brass (Body C with stainless steel seat 1.4112, except NBR version) or stainless steel 1.4581
• Pressure valves: Gauge pressures for the prevailing atmosphere pressure

Performance data

Duty cycle

The valve is designed to work continuously at its full capacity without overheating or wearing out (100% continuous rating).

Switching time

The switching time is the time the valve takes to go from one state to another, typically from fully open to fully closed or vice versa. Table 1 shows the valve's opening and closing times for AC and DC signals.

Signal	Opening time (ms)	Closing time
AC	10 - 20	20 - 30
DC	20 - 80	20 - 30

Medium data

Table 2: Valve materials and their compatible media

Material	Compatible media	Suitable temperature
NBR	Neutral media, compressed air, water, oil	-10 - 80 𐩑C (14 - 176 𐩑F)
FKM	Hot air, hot oils, oils with additives	-10 - 130𐩑C (14 - 266 𐩑F)

Process/port connection & communication

• Electrical connection: Cable plug for Ø 7 mm cable is supplied as standard

Approvals and certifications

The valve satisfies IP65 degree of protection, indicating it is dust-tight and protected against low-pressure water jets from any direction.

Circuit function

The valve works as a normally closed solenoid valve with two ports.

Other features

Burkert Type 0256 plunger solenoid valve can be combined with:

• Type 2518 cable plug, form A, following the DIN EN 175301-803 standard. This compatibility allows for a secure electrical connection between the valve and the cable plug.
• Type 1087 timer form A, according to DIN EN 175301-803. The timer helps introduce a delay in the opening or closing of the valve after receiving a signal or command. This feature is beneficial in certain applications where precise timing is required, such as controlling the fluid flow duration, regulating dosing processes, or coordinating the valve's operation with other components in a system.
