1. Leakage of sealing strip
2. Rapid aging of diaphragm
In the high-level development and design performed by the vika team, demonstrations and tests were conducted iteratively in view of common faults. Changes were then made with regard to welding process, seal size, and material design. A highly hermetic and durable valve chamber cover thus came into being.

Advantages of vika 03L103469:
1.The molded plastic PA66-GF30 parts of BASF brand are more resistant to high temperature and consequently more durable;
2.The oil seals and sealing strips, made of ACM from world-renowned Dupont brand, are highly resistant to heat, oil, and ozone, and provide greatly improved airtightness;
3.As diaphragms are produced with fluorosilicate, a top-grade material, they are less vulnerable to the corrosion of oil, acid, and alkaline, and perform more persistently and stably;
4.A welding process based on EMERSON welder leads to a dimensional tolerance of 0.02MM and maintains excellent product consistency.
