TRIANGLE Filtration has a range of 80-200mm corrosion resistant wafer check valves with flow indicating stem and optional microswitches available.
Materials of construction include glass filled polypropylene, EPDM and 316 stainless steel.
Standard units come with a flow indicating stem, which protrudes when the valve is in the open position. A micro-switch can be fitted onto the stem for an electrical output to monitor flow in the pipeline.
The set point of the micro-switch can be adjusted to suit each individual application. This is particularly useful to protect pumps and systems from no-flow or loss of prime situations.
Available sizes are: 80, 100, 150 and 200mm NB. Pressure ratings are PN16 for the smaller 80 and 100mm valves, and PN10 150 and 200mm valves. Triangle Filtration 03 9580 2122.
