Seal type: NBR
Supplied without coil: requires Type 3
Connector type: CNE Small sold separately

Note: Third port has M5 thread

The Series 305 is an established family of brass 3 way direct acting poppet type solenoid valves. Available in 3-way normally closed, normally open and Universal versions. The Universal version can be connected as either a normally open or normally closed valve, this is especially useful in situations where field-engineers are required to fit the valve on site and where the configuration of the solenoid valve can only be decided at time of installation.

The body is manufactured from hot-stamped brass with 1/8" G (BSP) ports and is also equipped with two holes threaded M3 to allow secure mounting. The armature-tube is also brass, the exhaust port on the armature tube is threaded M5. The armature(plunger), return spring and seal spring are stainless steel. The seals can be supplied in NBR, FPM or EPDM.

These valves require a solenoid coil from the ACL Series 3 range. ACL produce two classes of coil suitable for use with the 305 valves - those with Class F electrical insulation allow the 305 to be used in an ambient temperature range of -10°C +55°C and those with class H coil an ambient temperature of -10°C +80°C. At these temperatures and at the coils' marked voltage these coils are rated for continuous service ED100%. These coils are compatible with standard DIN connectors, when fitted environmental protection is rated as IP65 with connector fitted IP00 without connector.

Options (call Beta Valve sales office for details):

Manual override
Degreased for oxygen
Stainless steel armature tube
Electroless nickel plating
Improved safety coil according to ATEX - EExmII. Series-7
Exhaust port with hosetail connection


The 305 series of valves can be used with fluids compatible with the materials of construction with a viscosity not exceeding 25cSt (mm ²/s).

The valve body is equipped with two M3 threaded mounting holes, for ease of integration into product design these valves may be mounted in any orientation.

** Dependent on valve/coil combination chosen.
