SUPCON LN81 Series Single Seat Globe Pneumatic Control Valve
Pneumatic Pressure Control Valve
Pneumatic pressure control valve is capable of regulating the system pressure to adjust the force on the hydraulic piston rod or the torque on the hydraulic motor shaft. Pressure relief valves are used to set the maximum pressure in the circuit and prevent it from being overloaded. Pneumatic pressure control valve permanently maintain the output pressure at the set value while preventing overloading of the equipment. Unloading valves are designed for economic pressure control in accumulator operating circuits and are used as a power source for emergency control.
Globe Control Valves use linear motion to move the shutoff member in and out of the seat surface. Their bodies feature a spherical cavity around the port area and are designed to regulate process flow when used in conjunction with an actuator assembly. Many single-seat bodies use a cage, three-way or fixed construction to hold the seat ring in place, provide spool guidance, and provide a means of establishing specific valve flow characteristics. Caged or fixed single-seat bodies can also be easily modified by replacing the internals to change the flow characteristics or to provide reduced capacity flow, noise attenuation, or to reduce or eliminate cavitation.

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.
