The ZF series large combination air valve has high mechanical transmission efficiency, low ventilation resistance, appropriate closing torque, high reliability, and can extend the life of the actuator. The blades are evenly stressed, without deformation, and the closing is more tight and smooth. The overall life is extended and the maintenance frequency is less.

1. Performance characteristics of ZF series large combination air valve

The single air valve has the characteristics of high temperature resistance and low leakage (≤ 0.5%);

The effective ventilation area is over 80%;

The combination method is flexible and can adapt to the needs of different ventilation sections;

Adopting an external (internal) linkage transmission mechanism to precisely adjust the blade opening;

The clearance between connecting rods can be adjusted, and the consistency of opening and closing of individual air valves is good.

2. Driver and installation method

The driving methods are divided into manual, electric, pneumatic, etc.

The installation methods are divided into horizontal installation and vertical installation.

3. The ZF series large combination air valve model is ZF-WxH

ZF: Product Name;

W: The effective width of the combination method, in millimeters, to be determined by the customer;

H: The effective height of the combination method, in millimeters, shall be determined by the customer.

4. High temperature resistance performance of ZF series large combination air valves

Extreme working temperature: 280℃/120min

Note: customers need to specify the usage function and feedback information of the combination air valve when placing an order.
