LN83 Series high control precision Cage Guided Globe Control Valve

LN83 series are single-seat LN8 series pressure balance control valves, one of
the three largest base type products. SUPCON Cage Guided Globe Control Valve
Use separate sleeve, large guide structure, balance pressure sealing ring,
high-performance nonmetal sealing ring, has a good dynamic stability, high
control precision, allow the pressure difference is big, the operating force is
small, large flow capacity, etc. Suitable working condition of normal
temperature, differential pressure, under the action of alternating stress
control.
Cage Guided Globe Control Valve Description
Long life
1. Cage guided globe valve Trims
According to the needs of the working conditions, different materials and
surface hardening treatment can easily be chosen to meet the requirements of
each function module of trim to improve its performance of the corrosion,
cavitation and erosion resistant, lengthen service life.
2. SUPCON Cage guided valve body
The body of LN8 series control valves consists of two passages from upper and
lower, forming a shape like letter "S". The design of an elliptical section
reduces the flow resistance and turbulent flow to keep the flow fluent. The
flap in the middle of upper passage can reduce the eddy flow and increase the
flow capacity.
3. Cage guided valve Actuator
The standard mate of LN8 series SUPCON Cage guided regulating valve is AM8
Multi-spring pneumatic diaphragm actuator, which can be used in many conditions
with the features of strong output force, high reliability, long lifespan and
extensive application. The output force changes with the number of springs. The
high stress resistant diaphragm, bearing maximum pressure of 0.5 MPa air
supply, gives control valve a reliable shutoff. This type of actuator has a
long life cycle with more than 1 million times.
High Precision
LN8 series Cage guided valve are designed strictly on the basis of the IEC
standard. Cage guided valve are the latest self-innovated modularized straight
stroke control valve of SUPCON. We divide the trims into three modules, namely
guide, control and seal module. We provide the best solution according to the
function of each module and make action, control and seal more reliable.
Each index, linear, hysteresis, dead zone and leakage, for example, is full
compliance with national standards.
Note: For below measured results, take LN8100 top guide single seat valve
(PN110) as an example.
