DOUBLE ECCENTRIC VALVES
DOUBLE ECCENTRIC VALVES
The VCL Double Eccentric Valve is a shut-off and control device designed for gaseous media in different industries, e.g. Iron & Steel, Non-Ferrous, Glass or Petrochemical. Due to a self-tightening effect, the Double Eccentric Valve ensures a perfect tightness in the preferred pressure direction. Related to a standard shut-off valve, the friction in the seat area is significantly reduced which leads to a long lifetime and low actuation torques. The rotation-symmetric sealing system allows an economic manufacturing and a simple installation of spare sealings in all suitable materials, reaching from different types of elastomers up to metallic compound sealings for high temperatures up to 600 °C. This valve can be installed in any position and fitted with different mechanisms (pneumatic, manual, electric or hydraulic).
DESIGN FEATURES OF
DOUBLE ECCENTRIC VALVES
- Fabricated construction
- Valve actuation in accordance with customer‘s
requirements (man. / electr. / hydr. / pneum.) - Internal and external (high temperature) shaft bearings

DESIGN
ADVANTAGES
- Almost no wear at the seats due to parallel and friction free opening and closing at the valve disc
- Valves can be used in gas- and steam (vapours) loaded atmopshere (incl. vacuum applications)
- Opening against full differential pressure
- Minimal friction and wear due to double eccentric geometry
