A new orifice gate valve for dry bulk solids handling has made two major advances. In one single modular design the valves have been specifically designed for solids handling applications. Manufactured in the USA by Vortex, Quantum is constructed from 12 lightweight components, this represents a 50% parts reduction compared with the Vortex orifice gate valve it replaces, simplifying its construction and maintenance. The main body has two stainless steel flanges, formed by cutting and press break technology. The orifice slide gate seals are maintainable while the valve is still mounted in the conveying line. A shimming system allows the user to increase or decrease the compression force on the blade. This feature allows the user to make adjustments to improve the valve performance, without removal from the line, thus reducing valuable downtime. Quantum valves are currently available for 2in to 14in pipe or tube sizes with any connection from ANSI and DIN to client specified special bolt patterns.
