- Meets application requirements with durable leak-proof body machined from bar stock
- Save time and money on maintenance with electrical assembly that can be easily replaced without removing the unit from installation so that the process does not have to be shut down
- Quick installation with fitting that installs directly and easily into pipeline with a threadolet, tee, or flange (see application drawings)
- Meets the most demanding applications with high pressure rating of 1000 psig (69 bar) for the brass body and 2000 psig (138 bar) for the SS body
- Solves customer flow application needs with choice of custom vane calibrated specifically for your application, Model V4, or field adjustable multilayer vane, Model V4-2-U (see set point chart)
