Connector type: CNE Large sold separately

The 306 series of valves are 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" or 1/4" BSP (G) body ports and is also equipped with two holes threaded M4 to allow secure mounting. The armature-tube, armature (plunger), return spring and seal spring are all stainless steel. The seals can be supplied in NBR, FPM or EPDM. These solenoid valves can be used with any media compatible with the materials of construction (select appropriate seal material!).

These valves require a solenoid coil from the ACL Series 2 range. ACL produce two classes of coil suitable for use with the 306 valves - those with Class F electrical insulation allow the 306 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
Stainless steel seat
Electroless nickel plating
UL approved coils

The 306 series of valves can be used with fluids compatible with the materials of construction with a viscosity not exceeding 25cSt (mm ²/s) this includes most common media: air, water, mineral oil based media and glycol based solutions.

The valve body is equipped with two M4 threaded mounting holes, for ease of integration into product design these valves may be mounted in any orientation.
