Solenoid Valve 25mm Glued Sleeves NC Plastic EPDM 0-0.5bar/7psi 230VAC 0131 51257
Burkert 2/2 way solenoid valve (type 0131) with 25 mm glued sleeves and a 230 V AC coil. The circuit function of the solenoid valve is normally closed (voltage = open). The valve is direct operating, so no differential pressure required. Suitable for max media temperatures of 50 °C (122 °F) and a pressure range of 0 to 0.5 bar (7 psi). Housing of plastic with EPDM sealing and a 20 mm orifice. The Kv-value is 6 m3/h (100.02 l/min at dp = 1 bar water).
Note: DIN connector not included.

Description
This is a Burkert direct operating 2/2 way solenoid valve with 25 mm glued sleeves and a 230 V AC coil. The valve has a plastic housing with EPDM sealing and an orifice size of 20 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. As it is direct operating, no pressure differential over the valve is needed to open the valve. Suitable for a pressure range of 0 to 0.5 bar (7 psi) and a maximum temperature of 50 °C (122 °F). The valve has a Kv-value of 6 m3/h, this translates to a flow rate of 100 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 7, which means 7 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 PVC housing is strong and lightweight and resistant to many chemicals, acids and alkali. 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. 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
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 0131 valve is a direct-acting toggle valve. Its housing can be made of PVC, brass, or PVDF. The valve is available in sizes with diameters up to DN 25 and can operate from 0 to 3 bar depending on the version. Thanks to the diaphragm-separation between the actuator and the fluid body, aggressive media such as acids and alkaline solutions can also be controlled safely. DC variants offer energy efficiency, which can contribute to a longer life cycle. The valve features a vibration-proof coil system design. An electric position feedback system determines the valve's state.
