BURKERT 20037122 Type 0330 is a direct-acting, media-separated pivoted armature solenoid valve. As a 3/2-way variant with circuit function T, it can be used universally for mixing or distributing applications. The solenoid coil is moulded with a chemically resistant epoxy, and the coil system is separated from the medium by a diaphragm, making it suitable for critical media such as aggressive acids and alkalis.

This specific model features a PVDF (Polyvinylidene fluoride) body, EPDM seals, and an NPT 1/4 internal thread connection. It operates at 120 V / 60 Hz with a pressure range of 0 to 10 bar and an orifice size of 2.0 mm.
