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. The LN8 series top-guided single-seat control valve is a top-guided, plunger-type single-seat control valve. It was certified by TÃ??V ISO15848 in 2019. It has the characteristics of high control accuracy, good sealing performance, simple structure and high versatility. Suitable for fluid control in globe control valve working conditions requiring high control accuracy. Bellows seal type can be used. Thousands of applications in the fine chemical, petrochemical, pharmaceutical and other industries.
