The SKP15 slow opening and fast closing valve actuator is generally installed on the upstream valve of a dual valve, mainly playing a role in safety cutoff and slow opening and fast closing. Due to its hydraulic drive, Siemens electric hydraulic actuators all have a slow opening and fast closing function, ensuring smooth flow release when opened. The SKP25.0 valve actuator adds a pressure regulating function on top of the SKP15 actuator. Unlike traditional pressure regulators, the pressure regulating membrane of the SKP25 does not directly contact the main combustion airflow and the force of the pressure regulating spring is not affected by flow changes. Therefore, the SKP25 can adapt to diverse combustion environments and ensure stable output pressure. It provides stable gas pressure for the operation of the burner, especially suitable for mechanical linkage or electronic proportional adjustment type burners. SKP25.2 valve actuator is a valve actuator that adds a setting spring on top of SKP25.0 and is suitable for two stage burners. The output pressure of the two stages can be adjusted separately, making debugging simple and convenient. SKP25.3 is a zero pressure regulating valve actuator developed on the basis of SKP25. Its output pressure and air pressure are 1:1, and can be adjusted slightly. SKP25.3 integrates three functions: pressure regulation, safety cutoff, and zero pressure regulation in one actuator, greatly reducing your pipeline components and making it economical and durable. It is mainly suitable for industrial burners or premixed gas burners. The clever design of SKP75... makes it possible to control the air fuel ratio, which can automatically change the gas output pressure according to changes in air pressure, and the proportion is adjustable. The combustion performance of the burner controlled by SKP75 air fuel ratio is not affected by external environmental changes, achieving cleaner and more complete combustion.
