Features

Non-return valves of cast iron or plastic for horizontal orvertical discharge lines in accordance with EN 12050-4.

Sulzer ball check valvesSulzer ball check valves are designed for use in drainage andsewer mains. The unique design of a ball check valve allows freemovement of the ball and at the same time a good seal. Inoperation, the ball moves so that the entire pipe cross-section isfree.Ball check valves are self-cleaning. Deposits on the ball whichmay form while it is in the closed position are removed by therolling movement of the ball as it moves from the closed to theopenposition.The ball recess chamber has a removable cover which allows forinternal inspection without the need to remove the valve from thedischarge line.When fitting to horizontal discharge lines the ball recess chambermust be positioned above the horizontal axis of the valve.

Sizes: G 1¼”, G 1½”, G 2”, G 2½” (with internal thread).            DN 80, DN 100, DN 150 (with drilled flange connection).

Rated pressure: 10 bar

Sulzer flap check valvesThe Sulzer flap check valve is a synthetic non-return valve for usein drainage and wastewater mains. Its two-piece design features asingle disc seal that operates on a moulded rubber hinge, andwhen open makes the total diameter of the pipe available for thepassage of the medium. This results in a minimal pressure dropand avoids deposits or blockage. Venting of the pipe can beachieved by removing the plug screw.

Sizes: G 1¼”, G 1½”/ G 2” (with internal thread).G 1½”/ G 2” converts between sizes by fitting/removal of threadedinserts (tool and inserts included).

For automatic level control, the KS float switch is impact- andshock-resistant, mercury-free and enviromentally friendly.Moulded using the latest overmoulding process which providesa fully sealed float switch unit.ApplicationThe KS float switch is used in liquids for control or signal activ-ation and operates by responding to the liquid level. It is alsosuitable for use in sewage.FunctionIn the KS float switch a ball moves, depending on the floatingposition, and operates a high quality micro- switch. The re-cessed rolling surface for the ball ensures trouble-free func-tioning even if the cable is twisted. Varying the switching differ-ential is achieved by adjusting the cable length at its fasteningposition.A minimum cable length of 50 mm corresponds to a minimumswitching differential of 100 mm. The switching height itself is set by raising or lowering the fix-ing point by means of an adjustable weight attached to thecable. Care should always be taken that the float switch canfloat upwards or downwards without any restriction.
