Ln85 Series Good Dynamic Stability Cage Guided Globe Control Valve - China

LN85 series are LN8 series pressure balance control valves products, one of the three basic has separable sleeve, large guide structure, adopt the molding spring, energy storage pressure balance ring.

Has a good dynamic stability, high control precision, allow the pressure difference is big, the operating force is small, large flow capacity, suitable for a wider temperature range of conditions, large pressure difference, under the action of alternating stress control.

Cage Guided Globe Control Valve 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 - Cage guided globe 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 - Globe valve Actuator

The standard mate of LN8 series Globe 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.
