Main springs play an important role in suction and discharge valves as a dynamic member.

These springs are responsible for keeping the leakage parts (VALVE RING / VALVE DISC / POPPET / CHAMBER) on the SEAT and creating proper CRAKING PRESSURE in the SUCTION and DISCHARGE valves.

In order to achieve optimal efficiency in the compressor, as well as to ensure that these springs are not broken in the working range of the compressor, it is necessary by considering of the environmental conditions of the spring, including the working temperature and the type of fluid in the connection, in the design, selection of materials and carrying out processes of the standard to make the necessary and sufficient precision in the manufacture of these springs.

The most important materials used by this company in making the mentioned springs are as follows:

S.S17-7PH , INCONEL X750 , ELGILOY , NIMONIC 90 , HASTELLOY

RaimandRad industry company has mastered the design and manufacture of all kinds of springs and is a pioneer in the design and manufacture of high quality springs by having enough experience and technical knowledge due to scientific research and carrying out numerous projects.

In terms of appearance, these springs are generally used in 3 forms: HELICOIL, PLATE and WAVE in suction and discharge valves:
