Product structure and delivery set
The product is delivered to the customer as a set, assembled.
The valve consists of the following main units: a body, inside of which a throttle valve is located on the shaft, which can rotate with the shaft inside the body. To limit the rotation of the damper, two half rings with gaskets made of microscopic rubber are fixed inside the body. The output end of the shaft is connected through a half-coupling to the driving lever of the actuator. The actuator is mounted on a bracket.
The damper can take two fixed positions:
- Closed - the damper plane is set at an angle of 90° to the body axis;
- Open - the damper plane is at an angle of 0° to the body axis.
