With the single acting seal, it is applied to slow/ medium reciprocating movement
or slow rotary movement of the hydraulic cylinder or cylinder. Sealing pressure
range is more widely, from vacuum to zero pressure, super high pressure, can
ensure reliable sealing requirements.
Advantages:
It can be used in reciprocating and rotary movement and can adapt to most fluids
and chemicals.Low friction coefficient, no crawling under precise control, good
anti-corrosion capability and good dimensional stability.It can withstand rapid
temperature changes No pollurion to food and medical liquid.Unlimited storage
