Insert Check Valves Watts Industries produces an extensiveassortment of plastic check valves. These check valves can be found in watermeters, shower and bath taps and safetyunits, but they are also used in boilers, hotwater boilers, pumps and (underfloor) heatingsystems. The check valves are also used in industrialsystems. This in-house production of check valvesallows us to respond adequately to marketdevelopments, with new products andimprovements on existing products.

INSERT CHECK VALVESCS015 DN10 The Watts check valve type CS015 is the latest generation of check valves.Not only do these check valves operate ideally, they also offer added advantages:- identical contours in open and closed position (stem of valve doesn't protrude);- variable outlet system, facing side or rear side.The innovative use of materials in these valves renders them more resistant to bothchemicals and high temperatures. The CS is also more compact than conventionalcheck valves, and therefore easier to fit!Approvals: Kiwa (NL), DVGW (D), NF - ACS (F), ETA (DK), SITAC (S), Belgaqua (B).Other diameters on request. 0Product dimensionsø 14.9-0.1ø 11.1 0.1ø 14.6 0.1O’ringø 15 -0ø 15.5 0.1max. ø11.7Mounting dimensions15 0.116.2 -0161.78modelCS0150.15DN10Art. noW149015685WI020 DN20 The Watts check valve type WI020 shows the inventive solutions ofWatts Industries.Our R&D made this check valve for our customers with the same performancesthey are used to.Other diameters and closing pressures are also optional.Approvals: Kiwa (NL), DVGW (D), Belgaqua (B), SITAC (S), GDV (DK), NSF (US).Other diameters on request.Mounting dimensions32.1 0.5min 14.54.1 0.129.75 0.54.7 0.122.1 0.50ø 35.9 - 0.2ø 43.5 0.1ø 35.7 0.1ø 27 - 30ø 36 0.1ø 45 0.13.5 0.05ø 39 H7ø 37 0.2min ø 31.83.3 0.1ø 24.2 0.2Product dimensionsø 39 m9ø 26.77 0.1min 6O’ringmodelWI02036.8 0.5Technical specificationsWorking pressureTesting pressureNominal operating temperaturePeak temperatureDiameter nominalDiameter nominalPN101600 kPa65 C90 C for 1h per dayCS015 DN10WI020 DN20Material ngArt. noW149020650POMPOMPOMNBRNBRStainless steelPressure loss-curve100delta P (kPa)delta P (kPa)Pressure loss-curveDN209080701009080706060505040403030CS015 - DN1020WI020 - DN2020101000.20.40.60.81.01.2 flow(m3/h)00.81.62.43.24.04.85.66.47.28.0 flow (m3/h)3
