Solenoid Valve NC Brass FKM Anti-Waterhammer Without Body 0290 122602
Burkert 2/2 way solenoid valve (type 0290) with a 230 V AC coil. The circuit function of the solenoid valve is normally closed (voltage = open). The semi-direct operating valve opens without differential pressure. Housing of brass with FKM sealing and a 12 mm orifice. The Kv-value is 1.8 m3/h (30.01 l/min at dp = 1 bar water). Low risk of water hammer thanks to dampened closing.
This valve has no fluidic body.
Note: DIN connector not included.

Description
This is a Burkert semi-direct operating 2/2 way solenoid valve with a 230 V AC coil. The valve has a brass housing with FKM sealing and an orifice size of 12 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. The semi-direct operating valve opens without differential pressure. The brass housing is durable, suitable for neutral fluids and resistant to many chemicals. The FKM (fluorine rubber or Viton) sealing has excellent chemical properties, is suited for most oils and solvents but it cannot handle hot water or steam. Please note that the internal valve parts, such as the stainless steel plunger and springs, are also in contact with the medium and must be chemically compatible. Consult our chemical resistance chart to verify compatibility of housing and seals with the medium. The valve's design prevents water hammering. The valve has an IP65 rating if properly connected.
Pros:
- Good protection against the environment thanks to the IP65 rating
- Solenoid valves open and close very fast compared to many other valve types
- Low risk on water hammer, thanks to the dampened closing
Cons:
- Solenoid valves are very sensitive to dirt and can only be used with clean liquids and gases
- The coil may get hot when energized. A well ventilated environment is recommended
Series:
The Bürkert 0290 valve is a semi-direct (servo assisted) solenoid valve of the S.EV series. The membrane features a fixed coupling to a plunger. This means that the valve opens without a differential pressure over the valve. It can be used for low pressure applications, such as gravity fed systems or closed circulating circuits. The valve is designed for a quiet operation. All UC variants have electronic control to achieve a high inrush current to open the valve and a low holding current to keep the valve in the opened position. This "kick and drop" system results in low power consumption and low heat generation, contributing to the 0290's extended lifecycle.
