2-Way
Electric Ball Valve
Solenoid Valve or Ball Valve?
Solenoid Valves:
The valve is actuated with an electric current through the solenoid (electromagnet).
  • Switches directly.
  • From 1/8 inch up to 2 inch.
  • Normally Closed or Normally Open.
  • Only for clean media.
  • Uses energy as long as electrically energized.
  • (Semi-)direct operated: from 0 bar pressure differential.
  • Indirect operated: from ±0.5 bar pressure diff.
  • Only one direction of pressure.
  • Brass, Stainless Steel or Plastic housing.
  • EPDM, FKM, NBR of PTFE seals.
Electric Ball Valves:
The flow is controlled with a drilled sphere (ball) which rotates around its axis, perpendicular to the bore. The ball rotates with the help of an electric motor.
  • Operates from 0 bar.
  • Close gradually (±10s).
  • Energy efficient.
  • 1/2, 3/4 or 1 inch.
  • For both flow directions.
  • Brass Housing / PTFE sealing.
  • Less sensitive to dirt.
NC = Normally Closed (most chosen): The valve is closed when the coil is not electrically energized.
NO = Normally Open: The valve is open when the coil is not electrically energized.

Indirect operated solenoid valves need a pressure differential over the inlet and outlet port for proper operation. If the pressure differential is too low (f.e. a gravity fed system or a closed circuit), only (semi-)direct operated solenoid valves can be used. These operate from a zero bar pressure differential.

The type of medium defines the material choice of the valve body and seals. By selecting 'Other', you can choose the material for the valve body and seals.

Tip: Use the material table.

1/8 inch 1/4 inch 3/8 inch 1/2 inch 3/4 inch 1 inch 1½ inch 2 inch
Most valves are provided with internal thread (BSPP = British Standard Pipe Parallel). Use the table as a guideline for sizing:
ValvePipe ∅
1/8 inch± 4 - 8 mm
1/4 inch± 6 - 12 mm
3/8 inch± 8 - 15 mm
1/2 inch± 10 - 16 mm
3/4 inch± 15 - 22 mm
1 inch± 20 - 30 mm
1½ inch± 25 - 50 mm
2 inch± 40 - 60 mm

Solenoid valves are supplied with a coil of choice for alternating current (AC) or direct current (DC).

Solenoid Valve
(orifice <3mm)

3-Way
Electric Ball Valve
(bore >8mm)
Solenoid Valve or Ball Valve?
3-Way Solenoid Valve (orifice <3mm):For small flow rate, such as actuation of a cylinder, a (small) fuel system, a test setup, etc.
3-Weg Electric Ball Valve (bore >8mm):For larger flow rates, such as central heating, irrigation, compressed air etc.
Choose the right circuit function. The upper diagram shows the flow when the coil is not powered. The lower diagram shows the flow when the coil is powered.

The type of medium determines the choice of material for the seals. By selecting 'Other', you can choose the seal material yourself.

Tip: Use the chemical resistance table.
