Butterfly valves

Henry Pratt designs and manufactures valves for fluid service in the wastewater industry. The company’s butterfly valves are used to regulate the flow of fluid in piping systems. The unique seat-in-body design reduces seat failure due to corrosive buildup in the valve and pipeline. A symmetrical lens-shaped disc or flow through disc (on 30” and larger) provides more strength and higher Cv/lower head loss resulting in energy savings.

Knife gate valves

The Fabri-Valve XS150 Knife Gate Valve, available from ITT, is now available in 14"-24" sizes. The knife gate’s design eliminates the leakage paths at the transition point between the perimeter seal and the chest seal, a problem that is common to other high performance knife gate valve designs. The new sizes join the existing line of valves that are tailored toward more demanding municipal wastewater installation conditions.

Automatic degassing Valve

Plast-O-Matic Valves has developed an all-thermoplastic, automatic, continuous degassing valve. The Series DGV was developed specifically for corrosive applications subject to outgassing, such as sodium hypochlorite, hydrochloric acid, and ozone systems. The normally open valve has an internal float that pivots an arm and seal assembly as it rises and falls. When liquid fills the system, the float rises and the valve closes.

Diaphragm valves

Amiad’s Raphael “No Spring” Diaphragm Valve ensures even distribution of pressure on the sealing area, prevents diaphragm deformation and provides longer service life. The valve contains a minimum number of moving parts and requires minimal maintenance. The patented rib-style diaphragm has several advantages: valve opening and closing is gradual and eliminates risk of water hammer, vibration and noise; it provides accurate pressure regulation at flow rates; full valve opening is obtained at a very low pressure; and one diaphragm controls the whole pressure range.
