Water Flow Regulators Brochure - Wittmann - #2

Housings molded ofreinforced polyphenylene oxide fortough industrial use.

EPDM O-ring seals are heat and water resistant.

Our sight tube is polyamide 12 which is superior, compared to competitors polycarbonate, when higher temperature water is used. Competitors charge extra for the better material. On our unit it is standard.

All units are 100% leak tested before shipping.

Reference marks are molded in, not painted on.

Thermometer is located directly in the water flow giving a more precise reading and a quicker reaction to changes. Competitor's thermometers are not in the water flow path.

Enlarged water passages minimize flow restrictions, deliver increased flow volume through the molds and enhance heattransfer performance. In fact, pressure drop from our regulators is about halfthat ofcompetitive units. That's an important difference if plant water pressure is low.

Competitor's regulators include a large diameter valve for the main seat which means regulation is not precise. With a very small mo­vement ofthe handwheel, the valve is opened almost completely. Our units have a smaller diameter seat which allows better adjustment of flow.

Wittmann Flow Regulators include precision.threaded brass inserts (Series 301) or brass sockets (Series 101) for yourwater hose connections, unlike poorly designed regulators which use leak-prone molded threads which can strip easily.

The water flow regulators are exceptionally easy to clean. A top access cap is simply removed and a brush (provided) quickly cleans the tubes without removing them.

Individual sight tubes can be easily removed and reseated, ifnecessary. Precision O-rings positively seal the sight glass, absolutely leakproofeven under maximum loads.
