Description

Semi-direct operated 2/2 way JP Fluid Control solenoid valve with brass body, 1/2 inch threads and a 24V DC coil. The circuit function of the solenoid valve is normally closed (opens when electrically energized). Suitable for systems with an operating pressure of 0 bar to 10 bar and a maximum temperature of 130 °C. The orifice is 10.5 mm and the Kv-value is 1.49m3/h. The Kv-value is used to calculate flow rate: at 1 bar differential pressure (water) the flow rate is approximately 24.8 l/min.

This valve has an EPDM seal, which is suited for (hot) water, steam and most basic substances. For oils, compressed air and fuels, FKM is recommended instead of EPDM.

Please consult the chemical resistance chart for other media.

The coil (type CS1-024DC) DIN - A with connector is provided with the valve. Other connector types, such as with an LED indicator can be ordered separately. The coil can easily be mounted on the valve. Never connect the coil to the power supply when it is not mounted on the valve to prevent the coil burning out.

Solenoid valves are electrically controlled valves which open or close by means of an electric current through a solenoid (coil). As long as they are electrically energized they consume energy. They open and close quickly. They are sensitive to dirt and can only be used with clean liquids or gases.

Important

  • Use clean liquids or gases. Solenoid valves are very sensitive to dirt.
  • Do not power the coil when the coil is removed from the valve. The coil will overheat and may burn out.
  • Make sure that the valve is suitable for the application and that the materials are suitable for the medium and temperature.

Descriptions

TermDescription
Solenoid ValveElectromechanically operated valve. An electric current through a solenoid is used to open or close the valve.
Semi-direct operatedSemi-direct operated solenoid valves combine the features and operation principles of direct and indirect valves. This allows them to work from zero bar, but still achieve a good flow rate. The plunger in the solenoid opens a 'pilot' port, allowing the fluid pressure to support opening of the diaphragm. At the same time, the plunger is coupled to the diaphragm, causing it to be opened without minimum pressure. Semi-direct controlled valves are sometimes called 'assisted-lift' solenoid valves.
2/2-Way2 ports (inlet and outlet) and 2 positions (open and closed).
Normally closedThe valve opens when the coil is energized (Normally Closed or NC).
EPDMEPDM is used for the seal material. EPDM is suitable for (hot) water, steam, and alkaline substances such as detergents. For other media FKM (Viton) is usually a more chemically resistant and durable alternative. View the materials compatibility overview.
24V DC24 volt DC. For most valve types different coils are available (380VAC, 230VAC, 120VAC, 24VAC, 12VDC, 24VDC). Always use the correct power supply.
Kv-valueFlow (m3/h) water of 20°C through the valve at a 1 bar pressure drop. The flow can be calculated with the formula: Q=Kv√dp. Example: The flow of a valve with Kv=0.5 in a system with a 2 bar inlet pressure and a free outlet can be calculated with: 0.5√2=0.7 m3/h, or 12 liter/min. For gases another formula must be used, the flow rate will be higher. A handy tool to determine the required Kv value is our Valve Sizing Calculator.
1/2 inchG1/2 inch pipe thread (BSPP). Determine the valve size based on the desired flow rate and pipe diameter. Using the range of fittings, you can connect the valve to the desired type of pipe.
