Lubricated Plug Valves

Grease sealed structure has been adopted for the outlet of the valve body which is especially suitable for the pipelines with grain slurry medium. There is a grease chimb in the plug surface, where the grease gets in with higher pressure than the slurry in pipelines, thus it forms an oil film to isolate slurry with the plug of rest state from getting into the gap between valve core and valve wall, which avoids the rubbing. Under the dynamic state of the plug, it generates high speed oil flow to impact slurry and prevent it from entering the gap. Ensuring normal operation of the plug valves, which enhances the economic functions of slurry pipeline transportation engineering.

Knife Gate Valves

Vahn-Tech DK Series Gate Valves are soft sealing shut off valves that are light weight with compact construction, and convenient to install and use.  Valves are in full port design and with small flow resistance.  When the gate is open, direct current flows between valve and pipeline.  Valves can be operated manually with handwheel, or with automatic actuator for remote operation.  The cone-shape design of the gates provides strong cutting force.  The die-casting rubber seats are with bi-directional sealing.  The main advantage of the valves is that when fully open, the medium will not flow into the valve chest, which prevents the pulp from settling in the valve chest and thus reducing the maintenance cost.

DBB Compact Manifold—Double Ball Valves

In the standard Vahn-Tech Trunnion Mounted Ball Valve, each seat ring provides tight shut-off sealing against pressure from both upstream and downstream ends of the valve.  The seats are designed to provide venting/bleeding the cavity between the seating surfaces.  This is a typical Double Block and Bleed (DBB) design.  In DBB valves the seats are "Self Relieving" due to the "Single Piston Effect", that allows for any excessive pressure in the body cavity to be discharged in the line.
