This document discusses manual adjusters for light, medium, and heavy throttle valves. It describes three different valve options: 1) The MEZ-DAMPER VALVE KS 25 for light valves up to 500 mm, which can be operated without a lever by grasping the gripping gap. 2) The MEZ-DAMPER VALVE KS 10 for medium valves up to 500 mm, which has an off-centre lever that can be operated from both ends. 3) The MEZ-DAMPER VALVE KS 25 with Lever HKS 25 for heavy valves up to 500 mm, which has a lever mounted on one side for easier operation of heavy valves.

Workmanship + Assembling:
- Eases the assembling of valves, the effort - Using resilient axle bolts eases
involved being reduced to the production and the installation of the damper blade
spot-welding of the damper blade - Damper blade can be set-up in every
- The duct walls are clamped between plate-like position without fear of a backlash
constructions and held stable in the process
MEZ-DAMPER VALVE KS 25 with Lever HKS 25
Heavy valve till 500 mm KL
Lever is built on one side
The large arm of the lever eases the operation of heavy valves

Workmanship + Assembling:
- A servo motor could be integrated at the lever end
- Do not tighten the locking lever
