Check Valves in CSO/SSO Systems

(CARNEGIE, PA - August 25, 2009) - When a combined sewer and sanitary sewer overflow system allows water to flow back to the sewage treatment plant, the result is unnecessary treatment of additional water. The Tideflex® Check Valve prevents the back flow by closing with the backpressure from the receiving body of water. The TF-1 Curved Bill Tideflex® Check Valve was specifically...

Spotlight on Check Valves

An often overlooked and sometimes misunderstood item used in fluid power circuitry is a device called a check valve. Their function is very simple, they allow passage of media in one direction while blocking the flow in the opposite direction. Lexair high flow check valves can be used with a variety of media including air (or other inert compressed gases), oil or liquids. Our valves feature a...

Tideflex Mixing System Eliminates Stagnation in Potable Water Tanks

(CARNEGIE, PA - November 18, 2008) Many potable water tanks or reservoirs depend on a typical common inlet/outlet to maintain drinking water quality. This system often proves inadequate when water outside the common inlet/outlet area of influence becomes stagnant, creating dead spots where bacteria are likely to multiply. Tideflex Technologies' Tideflex® Mixing System (TMS) greatly improves...
