Microfinish Valves Inc.

Microfinish is a leading manufacturer of high quality, low emission API 6D trunnion mounted and ASME B16.34 floating ball valves. Within this product line is offered a full range of cryogenic ball valves which are manufactured in a state-of-the-art production facility in Hubballi, state of Karnataka, INDIA, and stocked in their sales and distribution center in Houston, Texas. 

In operation since 1971, Microfinish has worked with EPC and end user companies and earned a reputation for quality and reliability in its comprehensive range of product line. It has established an extensive installed base of industrial ball valves in high alloy materials for corrosive service, metal seated designs for high temperature and abrasive services and cryogenic designs for low temperature, cryogenic and deep cryogenic service applications for gas plants, ethylene plants, Air Separation Units (ASU), LPG export terminals and the entire LNG value chain. 

• Cryogenic trunnion mounted ball valves available in DBB or modified DIB-2 seat designs
• Cryogenic floating type ball valve
• Manual and Automated package 

Microfinish introduced to the market a distinctive design of trunnion mounted ball valve for cryogenic service. 

The design is built as per BS6364 and API 6D, modified DIB-2 configuration. With the valve in its closed position, both upstream and downstream seats work in tandem to block in-line leak in the preferred direction. Cavity pressure build-up, due to thermal expansion, is released safely through the upstream Single Piston Effect (SPE) seat. Microfinish’s proven valve design increases significantly the MTTF and MTBF of trunnion mounted valves in extreme cryogenic temperature conditions, and hence maximizes plant productivity and site safety.
