Solenoid Valve DF-SB 3/4'' NO brass EPDM 0-3bar 12V DC
JP Fluid Control 2 way solenoid valve (type DF-SB) with G 3/4 inch threads and a 12 V DC coil. The circuit function of the solenoid valve is normally open (voltage = close) and semi-direct operating, so no pressure differential is required. Suitable for max media temperature of 120° C (248 ° F) pressure range of 0 - 3 bar (0 - 44 psi). Housing of brass with EPDM sealing and a 20 mm orifice. The Kv-value is 6.48 m3/h (108.02 l/min at dp=1 bar water).

Description
This is a JP Fluid Control semi-direct operating 2 way solenoid valve with G 3/4 inch threads and a 12 V DC coil. The valve has a brass housing with EPDM sealing and an orifice size of 20 mm (approximately 3/4 inch). The circuit function of the solenoid valve is normally open, which means the valve closes when voltage is applied.
The valve is suitable for pressures of 0 - 3 bar (0 - 44 psi) and a maximum temperature of 120° C (248° F). The valve has a Kv-value of 6.48 m3/h, which translates to a flow rate of 108.02 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 7.49, which means 7.49 GPM @ 1 psi pressure drop. For simple applications it is often 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 brass housing is durable, suitable for neutral fluids and resistant to many chemicals. The EPDM (ethylene propylene diene monomer rubber) sealing is suitable for neutral fluids and many chemicals, but it has poor resistance to oils and fats. 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:
- Solenoid valves open and close very fast compared to many other valve types
- Delivered including coil and connector
- Semi-direct operated valves work from 0 bar, which makes them suitable for low pressure or gravity fed systems, circulating closed circuits or even rough vacuums
- EPDM is suitable for (hot) water, neutral fluids and many chemicals
- Good protection against the environment thanks to the IP65 rating
Cons:
- EPDM is not suitable for oils and fats
- If your pressure differential is always higher than 0.5 bar, an indirect operated solenoid valve could be an alternative with better energy efficiency and lower total costs
- Solenoid valves are very sensitive to dirt and can only be used with clean liquids and gases
- Solenoid valves use energy while activated and the coil may get hot. A well ventilated installation environment is recommended to dissipate the heat
DF-SB series
The DF-SB is a semi-direct operated 2/2-way solenoid valve (normally open). The solenoid valves have an orifice of 16 mm up to 25 mm, they operate from 0 bar and are suitable for medium flow rates. The body is available in brass or stainless steel with NBR, EPDM or FKM seal. The DF-SB solenoid valves are compatible with all the coils from the CS2 series.
The valves are available with BSP or NPT threads on request.
