STP Top Guiding Parabolic Plug Type
STP is the basic type among SH6000 high performance control valves. Metal-seated quick-changeable
trim combination. Insensitive to impurities with low cavitation design. Fast and easy to maintenance due to
its rotational symmetry. This series is characterized by optional metal to metal sealing and PTFE-soft
sealing supported by an additional Elastomer O-ring. STP series can be used in a wide range of applications,
especially suitable for the fluid with entrained particle and larger temperature variety because of won't
being locked.
