• Choice of custom vane calibrated for your application, Model V4, or field adjustable multilayer vane, Model V4-2-U
• Weatherproof, designed to meet NEMA 4
• Explosion-proof
• Installs directly and easily into pipeline with a threaded branch connection, tee, or flange
• Can be used in pipes 1-1/2" and up
• Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
• High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138 bar) with the 316 SS body
  DYWER V4-2-U-AT FLOW SWITCH VANE OP.. Rugged and reliable the Series V4 Flotect® flow switch operates automatically to protect equipment and pipeline systems against damage from reduction or loss of flow. The V4 is time tested being installed in thousands of pipelines and processing plants around the world. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm.

Feedback
Thank you so much. My order was really small but you'd never know that from the service I received. The sales staff really put themselves out to help. Absolutely faultless from start to finish.
...Eila McGeary
You did exactly what you promised and the goods turned up sooner than quoted which doesnt often happen.
...AdamsGale
Very satisfied, good service, product delivered on time. Your initial estimate for delivery was a little optimistic 5 days not 2 to 3. Overall quite happy.
...David Johnstone
I do think your charges for posting and package expensive. After waiting a week I telephoned your office to say that my kit had not arrived. I was impressed with the lady who rang your High Wycombe branch and I received the goods the following day.
...Paul Morris - 8 Greenhaven Rise
A pleasuure to deal with, plus the cheapest I could find on the internet, although the delivery was a bit slow, but within time stated.
...MR MIKE BUTLER
Very fast delivery. Product best price i could find on the net. Many Thanks Ron
...Ron Ragan
Box was delivered on specified date. Box was damaged but contents seem fine. Good service, thank you
...Christine Redshaw
I placed my order online and was kept up to date with how things were progressing. I received an email to tell me the part was available for collection. However when I went to collect the part it was not available. Apparently someone had sold it. I contacted Christine who reordered a further one. After a week it was still not at the Belfast Depot so I contacted Christine who arranged for it to be delivered to me Free of Charge
...Alan McCullough

...Conrad Gurnett
Excellent overseas service. Quick and helpful.
