Introduction

Thank you for your interest in our products.
Below you will receive some detailed information on our line of Stargate O-Port® valves and Automatic Screens. With our valves we are mainly replacing ball valves with our products but also replace knife gate or wedge gate and butterfly valves. These replacements happen in those applications in which these valves do not perform.

For the past twenty-five years our Stargate O-Port® valves have been used in the pulp and paper industry and for about 4 years also in the chemical industry very successfully. We have supplied specialty valves in the USA, Canada, Norway, Indonesia, India and Venezuela.
Big Blow™, Big Cap™, Big Knife™, Big Screen™, Big Wafer™, and Stargate O-Port® are our trade names. The valves are used as blow valves, capping valves, liquor supply line valves, screens, pump-, washer-, mixer-, or tower isolation-valves, lime storage bin valves, liquor heater valves, fly ash bin valves and others more, specially in applications where other valves do not perform, have a shorter life than a year or cause much maintenance cost.

We manufacture our Stargate O-Port® s in stainless steel, Hastelloy, titanium, SMO, even carbon steel or any other material available in plate.
During the past ten years, one theme has become very important for the use of our Stargate O-Port® s, i.e. the possibility to use our Stargate O-Port® valves instead of setting blanks. With a mill in eastern Canada, we followed a project very closely which started about eight years ago.  The project involved replacing all blow valves and liquor supply line valves. This project had an investment amount of $300,000. 
The pulp mill superintendent recently told us that over these years, the mill has made several million dollars because of the concept we proposed with our products and because of being able to work safely behind our Stargate O-Port® valves.  It now only takes several minutes to close the Stargate O-Port® valves without stopping production and lock them so they can do inspection and maintenance on a digester, whereas it did take several hours with production stopping.
It may be of interest for you to know that OSHA recognizes our Stargate O-Port® valves as blanks.
As you can see, our products serve a tripple purpose: They are valves and line blanks at the same time. In addition flow can be controlled with this valve.
We have also included  below some information on projects we have lately worked on.
Please look this information over and let us talk about your specific interest in reducing down time and maintenance cost.

Application Information for SVC Stargate O-Port® Valves

For the past twenty-five years our Stargate O-Port® valves have been used in the pulp and paper industry and the chemical industry very successfully In 2000 we have started to supply into the mining industry. We have supplied in the USA, Canada, Norway, Indonesia and India.

Big Blow™, Big Cap™, Big Knife™, Big Screen™, Big Wafer™, and
Stargate O-Port® are our trade names.

The Stargate O-Port® valves are used as :

  • Blow Valves

  • Capping Valves

  • Liquor Supply Line Valves

  • Automatic Screens

  • Pump Isolation-Valves

  • Washer Isolation-Valves

  • Mixer Isolation-Valves 

  • Tower Isolation-Valves

  • Lime Storage Bin Valves

  • Liquor Heater Valves

  • Heavy Black Liquor Valves

  and others more, especially in applications where other valves do not perform, have a shorter life than a year or cause much maintenance cost.

  Areas of application in the pulp mill are for example:

  • Batch Digesters

  • Continuous Digesters

  • Blow Tanks

  • Stock Pumps from Blow Tank

  • Washers

  • Mixers

  • Stock Pumps

  • Bleach Towers

  • Up-flow Bleach Towers

  • Liquor Heaters

  • Lime Storage Bins

  • Recovery Boiler

  • Green Liquor

  • Pulp Storage Tanks

  • Manifolds for High Consistency Stock

  • Fly Ash Bin 

 

We manufacture our Stargate O-Port® valves in

  • Stainless Steel

  • Hastelloy

  • Inconnell

  • Zirconium

  • Ttitanium

  • SMO

  • Carbon Steel

    or any other material available in plate.

No more Blank-Setting

A very important reason for the use of our Stargate O-Port® valves is the possibility to use our Stargate O-Port® valves instead of setting blanks. Working safely behind our Stargate O-Port® valves has saved mills several million Dollars.  It now only takes some minutes to close the Stargate O-Port® valves without stopping production and lock them so that inspection and maintenance can be performed downstream.

We are mainly replacing ball valves with our products but also knife gate or wedge gate and butterfly valves.
