Blades: High quality galvanized steel 'V' grooved blades having 150mm height or as per client requested height blades. Linkage Details: Standard 3mm thick x 20mm Electro Plated Linkages Spindles and bearings: Outer 14.5 mm / Inner 9.3mm Electro plated EN-1A bush bearings and 9.2mm x63mm long electro plated spindle rods or brass bushes as per client's requests. Locking Quadrants: for manual operated VCD's Heavy gauge galvanized steel handle position indictor with locking screws. Motorized volume control dampers are supplied with high quality knurling electro plated shaft and motor fixing bed provisions to mount the actuator. VCD's will be supplied with suitable torque / model actuators as per client request

Implementation

Frame with flat frontal face and inner 'V grooved multi blades assembly. Frames are welded and inner blades are connected to the frame by means of spindle rods and bushes. Bushes are available in brass / bronze. All blades are connected by a suitable flat link arrangement with handle to operate the dampers in opposed blades type operation with status indicator lockable screws indicating open or closed position. Available in manual control or motorized control operations, as well as in standard or Non-Standard sizes also available. For motorized operation extended spindle rod will be provided to fix the motor. Actuators available with various torque capacities to meet the large size requirements
