Self-acting temperature control valve


Self-acting temperature control valve, using the change of the temperature of the controlled medium itself for adjustment. The temperature control range is from 20~100℃, with a wide temperature setting range and overheat overload protection measures. The temperature setting is convenient, indicated by a temperature dial during setting, and can be continuously set during operation. <br/> Widely used in petroleum, chemical, dyeing, pharmaceutical and other industrial sectors, as well as urban heating and heating systems.

Self-acting low-pressure regulating valve / Self-acting differential pressure regulating valve


A self-acting pressure differential valve is a device that automatically adjusts the pressure difference of one or two media without the need for external energy, maintaining a constant pressure difference. For example, in industrial furnace gas combustion systems, it is used to control the mixing ratio and flow rate of two fuels (fuel A and fuel B) to achieve ideal combustion conditions, saving fuel and investment. It can also be used in pressure reduction, micro-pressure, and differential pressure regulation systems for various industrial gases such as coal gas, natural gas, liquefied petroleum gas, ammonia, nitrogen, and oxygen. It can also be used in hydrogen-cooled generator unit sealing oil systems to control the pressure difference between the sealing oil and oxygen to ensure reliable sealing.
