Product Detail Pages
 | 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. |
 | Stop production, take flanges loose, drop pipes and replace screens is a frequent task. Big Screen™ will reduce the down time for maintenance purposes. |
 | 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. |
 | Excellent performance with an absolute minimum of maintenance. This valve is built rugged enough to withstand almost any problem related to the batch pulp digesters. |
 | Their generic terms are: (Slide gate valves, O-port gate valves or through port valves). Their design is rugged for applications with high temperature and pressure shock waves. |
 | The double seats are solid filled PTFE for temperatures to 450 degrees fahrenheit. They are spring loaded for long lasting drip-tight shut off even with abrasive medium. For higher temperatures graphite seats are used. |
 | Most valves are actuated by type "A" pneumatic actuators, i.e., the top quality cylinders for longest life even at high cycle rates. The actuators are epoxy-painted; cylinder rods are stainless steel for corrosion resistance. |
 | The valves are supplied with locking devices LO, for mechanically locking the valves in the closed position, preventing accidental opening of the valves. This allows work behind the locked valve without the necessity of selling blanks thus decreasing the downtime. |
 | Micro limit switches, Go proximity switches or any other limit switch based on customer preference indicating open or closed position are provided. Also, the supply of solenoid valves to activate the cylinders is an option. |
 | When scale is formed on the moving elements of ball valves or gate valves the consequence is either blocking of the valve movement or damage to the valve seats and consequent leaking through the valves. |
 | The Stargate O-Port® Diverter valve can be applied to a variety of applications where flow of material has to be diverted from one line to another. The Stargate O-Port® Diverter valve has been used in chip feed applications to divert chip flow from one digester to another. |
 | 20” Stargate O-Port® Capping Valve with Steaming and Evacuation. For full automation of the filling of the digesters, capping valves are used instead of manually installed blanks. |
