BURKERT 93911864 is a Type 0331 direct-acting, media-separated pivoted armature valve. As a 3/2-way variant (Circuit Function E), it is used as a mixing valve where normally inlet port 1 (P1/NC) is closed and inlet port 3 (P2/NO) is connected with outlet port 2 (A/OUT). The solenoid coils are moulded with a chemically resistant epoxy. Since the coil system is separated from the medium by a diaphragm, the valve is especially suitable for critical media such as aggressive acids and lyes.

The 93911864 model features a stainless steel body with a flange connection (Bürkert flange 32 x 46 version A2) and EPDM seals. It operates on 24 V DC and handles a pressure range of -1.00 to 5.00 bar with a 3.0 mm orifice. The valve is equipped with a service-friendly, robust manual override for start-up and testing.
