 Design introduction

屏幕截图 2025-10-09 132855The particular characteristics of WQ are the seal profile with a defined seal edge and the use of two O-Rings as energizing elements to optimize the pressure profile and to reduce gas permeability



Advantages

  • High sealing effect

  • Double security through the combination of low-friction special materials with elastomer seals

  • Low gas permeation rate

  • Outstanding sliding properties, no stick-slip effect

  • Diameter from 25 to 700 mm
