Beta Valve supply a wide range of 2 and 3 way, high quality, general-purpose stainless steel solenoid valves manufactured by ACL srl, whose solenoid valves are used in demanding applications around the world. These robust all stainless steel solenoid valves can be used in many industrial, medical and scientific applications to control a wide variety of fluids that are compatible with the materials of construction.

  • All stainless steel construction – suitable for controlling most industrial fluids including pure water, aggressive media, steam, oxygen, vacuum, air and many gases.
  • Wide range - we offer both 2 way and 3 way stainless solenoid valves with normally closed or normally open operation from a single source.
  • Latching (bi-stable) versions of many 2 way stainless steel solenoids - For battery powered or other applications requiring low power consumption.
  • High quality stainless steel solenoid valves from a leading European manufacturer. – Dependable, long-term stainless solenoid supplier for OEMs.
  • 2/2 and 3/2 ss solenoid valves from stock – Easy availability.
  • 1/8" to 1"BSP port sizes in stock – Size to suit application.
  • Available in both AC and DC operation – Simplifies electrical circuitry.
  • FKM/FPM & EPDM seal material as standard NBR (Buna) optional – for maximum compatibility with many common and agressive industrial fluids.
  • Many options including: Manual override, food approved seal material, slow-closing diaphragm, silver shading ring, degreased for oxygen and approved coils for hazardous areas.
  • Custom solutions are available in OEM quantities.

Direct Acting Stainless Steel Solenoid Valves

Our direct acting stainless solenoid valves from ACL are available with port sizes from 1/8" to 1/2" BSP. These proven all-metal poppet valves can operate over a pressure range from zero up to the valves maximum differential pressure (up to 40 bar depending on type). Our direct acting stainless steel solenoid valves feature a compact physical size and offer fast response times of typically 8-25ms for air and 12-40ms for liquids depending on viscosity and on valve type. In 1/8”G(BSP) ACL offer the normally-closed Series 111 and the normally-open Series 211 stainless steel solenoid valves. In sizes ¼” to 1/2”G(BSP) the normally-closed Series 110 and the normally-open Series 210. Depending on type and size these stainless solenoid valves will operate over a pressure range from zero to up to 40 bar, with a maximum pressure rating of up to 100bar.

3 way Stainless Steel Solenoid Valves

Our 3-way stainless steel solenoid valves are available in normally closed, normally open and universal form. We normally stock the 3-way stainless steel solenoid valves in 1/8” and 1/4” sizes with FPM/FKM or EPDM seals, Buna (NBR) seals are available to order. Like other direct acting solenoid valves the operation of the valve depends only on the forces produced by the solenoid coil's magnetic field and the return spring acting on the valve's armature, allowing these stainless solenoid valves to operate with zero pressure. ACL offer the normally-closed, normally open and universal (valves that can be used for normally open or normally closed operation) versions of the 1/8”G(BSP) Series 311 and the ¼” Series 310 stainless steel solenoids. Depending on size these valve will operate over a pressure range from zero - 15 bar.

Servo-assisted steel solenoid valves

Servo-assisted solenoid valves generally offer the benefits of significantly lower cost and power consumption when compared with similar sized direct acting solenoid valves offering similar performance in terms of flow rate and maximum operating pressure. Because they require a minimum pressure to open the diaphragm servo-assisted valves are not generally suitable for situations where they are expected to open with zero pressure. ACL offer the normally-closed Series 177 and the normally-open Series 277 both are supplied as standard with AISI 316 stainless steel bodies with threaded port sizes from 3/8” to 1” G(BSP). Depending on size these stainless steel solenoid valves will operate over a pressure range from 0.15 - 15 bar (see datasheet).


To extend the usefulness of ACL’s stainless steel solenoid valves still further a range of options are available: Where the stainless solenoid valves are to use an a.c. supply when controlling pure water, a silver shading ring can be specified to replace the standard copper shading ring. If the valve is to be used with oxygen the valves can be factory degreased.

On request our ss solenoid valves can be supplied with coils approved to VDE or UL on selected voltages.

ATEX Approved stainless steel solenoid valves for use in hazardous or potentially areas (due to the gases, vapour or dust in the atmosphere)can be supplied fitted with ACL’s Ex m or Ex d approved solenoid coils.


ACL's stainless steel solenoid valves are employed in a large variety of industrial, medical and scientific sectors:

  • Water treatment – pure water use, aggressive media
  • Industrial process – steam, aggressive gases
  • Heating and air conditioning – condensate handling
  • Medical equipment – air, oxygen, other gases and liquids
  • Textile - dyes and inks
  • Food – steam, fruit juices
  • Pneumatic – high pressure air
  • And many more......
