LN81 Series Single Seat Globe Control Valve
Classification of pressure control valve
In the pneumatic transmission system, all pressure control valves work on the principle of balance between air pressure and spring force, which can be divided into the following three categories:
1. Pressure reducing valve. Also known as pressure regulating valve, setting device (precision pressure reducing valve), etc., it plays the role of pressure reducing and stabilizing;
2. Overflow valve. Also known as safety valve, pressure-limiting shut-off valve, etc., it plays the role of pressure-limiting safety protection;
3. Sequence valve and balance valve. Depending on the pressure of the gas circuit, some control is performed.
Next, we mainly introduce you this single-seat cut-off pressure control valve.



Single Seat Globe Pressure Control Valve advantages:
Hydraulic pressure control valve has Long life
1. Single Seat Globe Control Valve 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. Pressure Control Valve body
The body of LN8 Single Seat Globe 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. Single Seat Globe Valve Actuator
The standard mate of Single Seat Globe Valves 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 applications. The output force changes with the number of springs. The high stress resistant diaphragm, bearing maximum pressure of 0.5 MPa air supply, gives globe valves a reliable shutoff. This type of actuator has a long life cycle with more than 1 million times.
High Precision Globe Control Valve
LN8 SUPCON-high performance Pressure Control Valve are designed strictly on the basis of the IEC standard. They are the latest self-innovated modularized straight stroke control valves 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 valves (PN110) as an example.
