DETAILS

All known pipe cleaning methods (e.g. pigs, brush cylinders, etc.) can be used with the body bore, resulting in minimal pressure drops.
A unique transverse seal, consisting of a transverse sealing profile and sealing compound, makes the body bubble-proof towards the atmosphere.
A mechanically retained round bead seal creates a bubble-tight closure at the edge of the gate.
Optimized box design to minimize solids build-up due to gate geometry.
The cross seal can be repacked at any time and under full pressure using the side seal screws.
Robust 4-post topwork for maximum load and a wide range of actuator types.
With its optimized port geometry, accumulated media is pushed out of the port guide and released into the hole by increased flow.
