Solenoid Valve G1'' NC Stainless Steel EPDM 0-16bar/232psi 110VAC Vacuum 290 54044
Burkert 2/2 way solenoid valve (type 290) with G 1 inch threads and a 110 V AC coil. The circuit function of the solenoid valve is normally closed (voltage = open). The valve is semi-direct operating, so no differential pressure required. Suitable for max media temperatures of 120 °C (248 °F) and a pressure range of 0 to 16 bar (232 psi). Housing of stainless steel with EPDM sealing and a 25 mm orifice. The Kv-value is 10 m3/h (166.7 l/min at dp = 1 bar water). Suitable for vacuum.
Note: DIN connector not included.

Description
This is a Burkert semi-direct operating 2/2 way solenoid valve with G 1 inch threads and a 110 V AC coil. The valve has a stainless steel housing with EPDM sealing and an orifice size of 25 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. As it is semi-direct operating, no pressure differential over the valve is needed to open the valve. Suitable for a pressure range of 0 to 16 bar (232 psi) and a maximum temperature of 120 °C (248 °F). The valve has a Kv-value of 10 m3/h, this translates to a flow rate of 167 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 12, which means 12 GPM @ 1 psi pressure drop. For many applications it is enough to select a valve based on the thread size and orifice diameter. For more accurate sizing, use the Kv-value with our easy to use valve sizing calculator. The stainless steel housing is very durable, strong and resistant to a wide range of chemicals with the exception of chloride solutions. The EPDM (ethylene propylene diene monomer rubber) sealing is suited for neutral fluids and many chemicals, but it has poor resistance to oils and fats. 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. Suitable for vacuum applications. The valve has an IP65 rating if properly connected.
Pros:
- Suitable for vacuum applications
- Good protection against the environment thanks to the IP65 rating
- Solenoid valves open and close very fast compared to many other valve types
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
- DIN connector not included
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.
