As it is a suspended type, there will be more time division restrictions in the device, for example, the weight can not exceed the range of the suspended spring damper. Also, if you add other attachments, you must pay more attention.
Quality requirements for suspension spring damper and accessories:
1. Suspended spring shock absorber and accessories shall be installed according to the regular direction, position and elevation, such as contraction valve and stop valve. Refrigerant shall be low in and high out. The air of the thermal contraction valve flows from the top to the bottom, so the resistance is small. The local packing above the valve port is always at the side of the low-pressure fluid, no matter whether it is opened or closed, so it is not easy to leak; Shanghai Songxia Pneumatic Butterfly Valve Co., Ltd. strives to sell spring pneumatic butterfly valves, rubber pneumatic butterfly valves and suspended pneumatic butterfly valves. It has rich experience in the industry and is worthy of user trust.

At this time, the air door in the carburetor is actually closed. When you release the wire drawing, the air door of the carburetor is turned over.
