The Burkert Type 0131 (20044260) is a media-separated, direct-acting toggle valve, 3/2-way distribution valve. Body and port: PVC plastic body, solvent-weld socket Ø 16 mm, orifice DN 10; sealing is made of EPDM. The diaphragm between actuator and valve body also allows aggressive media to be switched.
Circuit function and pressure range of version 20044260
As a distribution valve, pressure port 1 (P) is connected to working port 2 (B) in the rest position and working port 4 (A) is closed. The valve is direct-acting and switches from 0 bar, i.e. without minimum pressure; the pressure range of this version extends to 1 bar, the Kv value for water is 2 m³/h. According to the data sheet, it opens in 10 to 20 ms and closes in 40 to 60 ms. The manual override with locking function simplifies commissioning and maintenance.
Actuator and connector of version 20044260
The coil for 230 V AC 60 Hz is moulded in chemically highly resistant epoxy and block-screwed, which makes it vibration-proof. The AC coil has a rated power of 16 W. It is connected via plug contacts to DIN EN 175301-803 form A; with a cable plug, the valve achieves IP65. The cable plug Type 2518 is included. Plastic bodies are connected to the line via union nut and connection fitting.
