LN81 Series Single Seat Globe Control Valve

LN81 series are single-seat LN8 series pressure imbalance structure products,
one of two basic guide plunger valve core, the floating sleeve compression
type, from the seat structure, modular design, the flow capacity is big, high
controlling precision, adjustable range, can achieve minimal flow control,
structure is simple, reliable, good seal performance, the scene is easy to
maintain. Is suitable for the pressure difference is not big, the seat leakage
and high control precision.
High Accuracy Globe Control Valve Supplier
Product Description
Long life
1. 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. Single seated globe valve body
The body of LN8 series single seat regulating valve 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. Actuator
The standard mate of LN8 series 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 Single seated valve has a long life cycle with
more than 1 million times
High Precision
LN8 series SUPCON Globe valve are designed strictly on the basis of the IEC
standard. They 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. SUPCON Globe Control Valve for sale
