- Excellent performance thanks to a special magnetically-activated switching configuration.
- Longer product life because to the free-swinging vane, which uses a straightforward lever arm instead of bellows, springs, or seals to activate a snap switch by drawing a magnet within the solid metal switch body.
- Long-lasting, leak-proof body made from bar stock satisfies application requirements.
- Electrical assemblies that are easily replaceable without removing the item from installation might save time and money on maintenance by avoiding the need to stop the process.
- Easy and quick installation using a threadolet, tee, or flange fitting that fits straight into a pipeline (see to the application drawings).
- High pressure ratings of 1000 psig (69 bar) for the brass body and 2000 psig (138 bar) for the SS body allow it to meet even the most demanding applications.
- meets the needs of customers for flow applications by offering the Model V4 field adjustable multilayer vane, which is calibrated especially for your application, or the Model V4-2-U,a custom vane (see set point chart).
