Ln83 Series High Control Precision Cage Guided Globe Valve - China

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.

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 - 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 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.
