What are the skills for matching pneumatic ball valves?
There are some tips for stopping the modification of pneumatic ball valve, which are explained below:
1、 Whether the upper and lower joint sleeves of pneumatic ball valves can be high-strength polyurethane sleeves is also an important basis for ensuring long-term high-strength use. It is difficult for ordinary ball valves to be used for a long time under high strength.
2、 Check whether the product can provide a 2-3 inch lift request. Some products only provide a 2 inch lift. It is easy to pull to the limit in off-road to cause damage after barely using the 3 inch lift.
3、 Whether the diameter of the central telescopic rod of the pneumatic ball valve can reach more than 16 mm is a basic indicator of strength. The pneumatic ball valve is mainly used to restrain the shock and impact from the road surface when the ball valve rebounds after shock absorption. When passing rough roads, although the shock absorption ball valve can filter the vibration of the road, the ball valve itself will also have reciprocating motion, and the pneumatic ball valve is used to stop the jump of this ball valve. If the pneumatic ball valve is too soft, the body will jump up and down. If the pneumatic ball valve is too hard, it will bring too much resistance, which will hinder the normal operation of the ball valve?
