Globe Control Valve 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. Cage guided valve Note: For below measured results, take LN8100 top guide single seat valve (PN110) as an example.

The LN8 series sleeve-guided control valve is a sleeve-guided, pressure-balanced single-seat control valve. It is TV ISO 15848 certified in 2019. It has a split sleeve construction and a high performance balanced seal ring seal. Suitable for fluid control in ambient and priming conditions. Bellows seal type is available. Thousands of applications in the fine chemical, petrochemical, pharmaceutical and other industries. Performance advantages Modular design concept, combining the and of high-precision control and the school of modular concept. The cage valve inner cavity of the valve body is S-shaped distribution, smooth and without dead ends; there are guide wings inside the valve body, which can reduce the mutual force of the medium inside the valve body and reduce the occurrence of cavitation. The use of sleeve guidance, large guide diameter, smooth guidance, with good dynamic stability. The cage valve seat adopts floating design, while the sealing surface adopts tapered form to ensure good alignment of the sealing sub. Sleeve window control flow characteristics, flow characteristics control accurately. The structure of the inner part is balanced, allowing a large differential pressure, small operating force and large flow capacity. Equipercent, linear and quick-open flow characteristics are available. Good use in the temperature range of -80 to 593 And pipeline connection with RF, RJ, FM and other flange type and SW, BW welding type. The flange distance conforms to GB/T 17213.3-2005 / IEC 60534-3-1:2000; or ISA S75.03-1992 standard. Cage Valve Part 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. 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. LN81 Series Single Seat Globe Control Valve 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 actuator has a long life cycle with more than 1 million times.
LN85Â series are LN8 series SUPCON 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.
The valve seat is made of high chrome molybdenum alloy that introduced by internal-combustion engine academe of uk which is the technology by the 90f+s, according to the situation of country, shanghai internal-combustion engine developed a new technology again which is melted by high temperature. So this material are be of high attrition endurance, high temperature endurance and high erosion endurance. Under normal condition, this product can make the engine drive 150~300 thousand kilometers. Our valve seats are suitable for engines imported from europe, america, japan, korean and so on, they are of the best quality and have the competitive price in home and abroad.

A valve guide is a cylindrical piece of metal, pressed or integrally cast into the cylinder head of most types of reciprocating engines, to positively locate a poppet valve so that it may make proper contact with its valve seat.
Top Guided Valve
control valve having an S-shape flow passage that features low pressure loss and a stabilizer that regulates turbulent flow around the cage, allows a large flow capacity, rangeability and high accuracy flow characteristics, noise reduction, applicable in various clean service and high differential pressure fluids.
