Filling valves, capping valves, for biomass reactor in Europe. High temperatures and acidity of the process require especially manufactured valves in Alloy 20 for high temperatures in the reactor. (read more)

The Quantum™ Series Orifice Gate™ is a significant innovation over Vortex_®'s original patented Orifice Gate™. Vortex_® utilizes precision laser cutting and bending technology to produce this leading-edge valve. It features an all stainless steel, weather resistant design with improved sealing, easier maintenance, and fewer parts. (read more)

Big Knife™ valves are a development to bridge the gap between the typical knife-gate valves, which are often called throwaway valves with all their many technical disadvantages, and the more expen­sive Stargate-O-Port valves, with some of the advantages of the O-port valves. (read more)

The main characteristic of this type of valve, also called slide-gate valve or through-port valve is the well-guided blade passing through both ends of the valve body, having a hole in the middle of the blade. The valves have a function similar to ball valves and perform better than ball valves. These are not knife gate valves. (read more)

SVC has developed special valves, based on the well known Stargate-O-Port® valves, for scale-forming or sticky materials. (read more)

SVC suggested to use the AS Stargate-O-Port valves for this application. In April 2000 the first valve, 12" diameter, was installed and has been in continuous service now with no need for taking the valves out of service, no need for removing scale. The application was in a gold mine for a slurry, which forms scale quickly. (read more)

These valves are used in applications where, for example, a positive displacement pump is feeding into the inlet of the diverter valve, which then allows the flow out of either of the outlet pipes. (read more)

This high pressure valve as a cylinder mounted on the side of the valve body acting on the blade via a cross bar. The O-Port design makes it possible to have perfect actuation with this design. (read more)
