Balaji Metacast Industries

Bowenpally, Secunderabad, Telangana

With the assistance of our team of professionals, we are engaged in manufacturing, exporting and supplying a wide range of Gate Valves. These are fabricated using high grade factor inputs as per the latest technological advancements to meet the international quality standards. Some of the salient features of these valves are corrosion resistance, high performance, accurate dimensions and longer service life. Further, our offered range is available in various specifications and can be customized as per the specific requirements of the clients.

Our Butterfly Valves are designed to meet the demanding requirements of the general utility valve market with the Water Pipeline and HVAC segment in particular. Our Valves are truly fit & forget valve, which requires minimal maintenance. The body liner which also functions as the soft seat, comes in an integrally molded (bonded) version and offers 100% bi-directional sealing against vacuum to rated pressures. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards

The presence of free air in pipeline can reduce the severity of water hammer considerably. Air in a rising main, whether in solution or in bubble from can have number of ill effects

Cavitation- The formation of vacuous cavities which subsequently rapidly collapse and erode the pump or pipe
Headloss- Accelerating water past air pockets formed in pipes, leading to head losses
Other formsmay include surging, Corrosion, reduced pump efficiency, malfunctioning of valves or vibrations

A pipeline designer therefore has to factor in all the aforesaid, the critical level of permissible vaccum inside a
pipeline to prevent collapse vis-a-vis the suction and discharge capacity of an air valve (curves on request) before
deciding upon the type, size, spacing and location of these air valves.

The choice of a check valve for pumping is always ticklish for a system designer. Quantum of head loss vs. non
slam characteristics, quick closing vs. dampened slow closure, vertical vs. horizontal application, spring assisted vs. self closing door, maintenance free long life at a relatively higher price vs. low price maintenance prone, are but a few arameters considered vis--vis application. We can help select the right valve that will be good value for money
