solenoid valves for vacuums | tameson.co.uk

Universal direct or semi-direct-operated solenoid valves are generally suitable for vacuum applications, because they don't require a pressure differential to operate. The pressure drop in a vacuum system is often only a few tenths of a bar. Therefore, valves that require an internal pilot pressure to open aren't suitable. The vacuum line must be connected to the output of the valve, so that the direction of flow is always from the inlet to the outlet port of the valve. 2-Way valves have two ports and can be normally closed (NC) or normally open (NO). 3-Way valves have three ports and can have different circuit functions. The article Solenoid valves for vacuum provides more background information.

Solenoid Valve or Ball Valve?

Solenoid Valves: 2-Way Solenoid Valve

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: 2-Way Electric Ball Valve

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.

Function:

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.

System:

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.

Medium:

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.

Most valves are provided with internal thread (BSPP = British Standard Pipe Parallel). Use the table as a guideline for sizing:

Valve	Pipe ∅
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

Voltage:

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