Indirect operated 2/2 way RPE solenoid valve with nylon body, 1/4 inch threads and a 24V AC (50Hz) coil. The circuit function of the solenoid valve is normally closed (opens when electrically energized). Suitable for systems with an operating pressure of 0.2 bar to 10 bar and a maximum temperature of 60 °C. For proper operation, this indirectly operated valve requires a positive differential pressure of 0.2 bar. For a closed system, such as a cooling unit, a directly operated valve or an electric ball valve is more suitable. The orifice is 11 mm and the Kv-value is 0.95m3/h. The Kv-value is used to calculate flow rate: at 1 bar differential pressure (water) the flow rate is approximately 15.8 l/min.
This valve has a NBR seal. NBR is suitable for cold water, compressed air and oils. For many other fluids, FKM (Viton) or EPDM have better general properties.
Please consult the chemical resistance chart for other media.
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.
|Solenoid Valve||Electromechanically operated valve. An electric current through a solenoid is used to open or close the valve.|
|Indirect operated||Indirect or servo operated solenoid valves use the differential pressure of the medium to open or close the valve. The minimum differential pressure is usually 0.5 bar. Since the fluid pressure is used, a relatively small coil can operate a large diaphragm and thus a high flow.|
|2/2-Way||2 ports (inlet and outlet) and 2 positions (open and closed).|
|Normally closed||The valve opens when the coil is energized (Normally Closed or NC).|
|NBR||NBR (nitrile rubber) is used for the seal material. Suitable for air, water and oils. NBR is unsuitable for ozone or acetone. EPDM is preferable hot water, steam and alkaline substances. For most other media FKM (Viton) is a more resistant and durable alternative. View the materials compatibility overview.|
|24V AC||24 volt AC (50Hz). For most valve types different coils are available (380VAC, 230VAC, 120VAC, 24VAC, 12VDC, 24VDC). Always use the correct power supply.|
|Kv-value||Flow (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.|
|1/4 inch||G1/4 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.|
