Bray Butterfly Valve as an Altitude Control Valve

Bray Butterfly Valve as an Altitude Control Valve

Product News Friday, December 02, 2011: Analytical Response t/a AR Controls

 

 

Let me share with you this application for its novelty and complexity at the second most important company in Colombia, MPE (Medellin Public Enterprises). On this application I want to highlight three very important aspects. First, the ingenuity
displayed by the project designer Mr. Juan Camilo Torres, who employed his creativity in solving a particular problem
in an area of difficult access with minimal economic resources. The second instance is the high demand and stress our Bray Valve is subject to as a final control element in a system of elevation of a water storage tank and treated water. Finally the comments of the engineer (Mr. Torres) after observing perfect operation (without bindings or jams) for a year and a half. He describes our product with the highest opinion and qualifications saying: “I found out that the Bray Valves are part of a
selected High Performance Valve group for the potable water industry, which provide reliability, durability, and maintainability”
 
Application: A 14” Bray Butterfly Valve Series 31, Trim 119 (Nylon Coated Disc) and actuated by a floating system designed and manufactured by MPE is used to regulate the inflow by gravity to a tank of glass fused to steel. The difference in head pressure is 40 m.c.a. (Approx. 56 PSI)
 
Advantages: Low cost compared to other possible solutions thanks to a FDA grade disc and seat (the only elements in contact with the fluid) eliminating the possibility of contamination of the treated water. Finally a hydraulic advantage was gained with the elimination of transient flows as a result of direct action of the valve disc, unlike the altitude control valves normally used (diaphragm type floating devices). In conclusion, the strong performance of the Series 31 valve for this complex application (which has always been committed to other types of valves and control systems) has found success at MPE.
