Globe Control Valve

Feature:
Suitable for clear fluid lines such as Water, Liquid, Gas, Steam, etc.
This valve is used in systems that require precise flow control and where leakage and air-tightness are critical.

Application:
It is essential for the flow line of each industry. Mainly used in plant automation facilities due to excellent precision control such as flow rate, pressure, temperature, etc.

Characteristics:
1. For excellent wear and tear resistance, Stellite welding is used by default on core
components such as plug and seat ring.
2. It is possible to achieve excellent durability of the unfavorable fluid condition and high
temperature through heat-treatment on parts of the stem and trim
3. The selection of accurate trim and material through extensive testing and rich
experience in technical solution
4. In case of a product related problem, we have technical personnel who can
immediately assess the situation and resolve the issue

A Globe Control Valve is a type of linear motion valve primarily used to regulate fluid flow in pipelines. It consists of a movable disk (or plug) and a stationary ring seat in a globe-shaped body. By raising or lowering the plug, the valve controls the flow rate. Globe valves are versatile and suitable for various applications, including throttling and isolation services in industries such as oil and gas, chemical processing, and power generation. Their design allows for precise flow control, making them essential components in process control systems where accurate regulation of flow, pressure, or temperature is required.

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.

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.

LN85 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.
