The Stargate-O-Port-Valve^® AS anti-scale valve eliminates scale formation concerns on Black Liquor Heaters, Evaporator isolation, and Green Liquor Clarifier system isolation valves. ClO2 generators also have a reputation for saltcake related reliability problems that is solved with the Stargate-O-Port-Valve^® AS solution.

The Stargate-O-Port-Valve^® 360 has a reputation for being the best suited solution for the most severe service applications where high performance ball, gate, and butterfly valves do not perform.  What about space limitations or multiple control range requirements?

The Big Blow^TM valve has a long history of providing un-matched reliability and low maintenance requirements in one of the most severe, critical, and demanding services in the pulp and paper industry.

Stopping production, taking flanges loose, and dropping pipes simply to replace a screen is a time consuming task that cuts into equipment availability. Big Screen^TM will reduce/eliminate the down time for maintenance purposes.

The Stargate-O-Port-Valve^® Big Cap™ offers a rugged digester capping solution with all of the desired safety features to optimize digester capping operations.

Fly ash from boiler systems is stored in bins for disposal or further processing.  With its internal friction characteristics, fly ash presents a problem for valve reliability.  SVC has the solution.

Scavenger valves are exposed to all types of debris in the media that requires a rugged, shearing solution.  The Stargate-O-Port-Valve^® Scavenger has the features to ensure smooth operation while ensuring no dewatered plugs are stifling operations or damaging downstream equipment.  Knife gates and iris valves do not present a reliable solution.  The Stargate-O-Port-Valve^® Scavenger valve has proven that it does.

Pocket valves are limited  in volume and, as a result, actuate on a short cycle causing premature wear. The Stargate-O-Port-Valve^® Sand Cleaner valve has a 40x volume to reduce cycle times and provides for efficient sand removal operations.

Deadheading of “siamese” valves can hinder operations or, worse, damage expensive equipment. The Stargate-O-Port-Valve^® Diverter Valve eliminates all possibility for deadheading.

Lime storage typically require some sort of isolation valve. In most cases, simple slide gates are used.  Besides the operational shortcomings, there are safety concerns with getting these slide gates to move when isolation is needed for screw feeder maintenance. The Stargate-O-Port-Valve^® incorporates specific design features that mitigate high internal friction and prevent material buildup from preventing proper actuation.
