Butterfly Valve for Long-Distance Water Transport

08 July 2017

The new Aporis double-offset butterfly valve with elastomer sealing element is now available from KSB Group, Germany, for applications where huge volumes of water need to be transported and shut off reliably. Applications include systems for water transport, water treatment or in large industrial cooling circuits.

The valve is available with the face-to-face lengths specified in the EN 558/ISO 5752, Series 14, standard and (© KSB Aktiengesellschaft, Frankenthal)(© KSB Aktiengesellschaft, Frankenthal)in nominal sizes DN 300 to DN 2000. The maximum permissible operating pressure is 16 bar, and the standard fluid temperature should range between 0 and 85 °C. The valve discs and bodies are made from epoxy-coated EN-GJS-400-15.

Two stainless steel stems hold the valve disc in position and torque transmission from the actuating stem to the valve disc is ensured by a keyed connection. Neither of the stems comes into contact with the fluid as they are surrounded by sealed protective sleeves, keeping them dry and, in conjunction with stainless steel reinforced PTFE bearing bushes, ensures extended, trouble-free service.

The flanged body with raised faces features integrally cast support feet which facilitate valve handling and storage. The type series is approved for drinking water applications (DVGW, WRAS and ACS).

What does "long-distance" have to do with these valves? Distance, per se, is never mentioned in the article. I had a vision of something quite different, based on the headline that led me here.
