一、进口自力式微(差)压调节阀概述

进口自力式微(差)压调节阀（美国威盾VTON），Self operated micro (poor) pressure regulating valve是一种无需外来能源的节能型产品，利用工艺管道中介质的压力变化与信号进行比较，使被调节介质的力与执行机构的输出力平衡，以达到稳定压力、差压值的调节阀。进口自力式微(差)压调节阀主要用于控制阀前压力小于0.2MPa，阀后最低可用5KP千帕的场合，适用于各种工业炉燃烧系统控制两种燃料气体混合比流量或用于氢冷发电机组密封油系统中，同时，还可用于各种工业气体的减压、稳压或泄压的自动控制。

美国威盾VTON进口自力式微(差)压调节阀，采用平衡单座阀，在运行中可任意对设定值进行调整等特点。因而适用于各种工业炉燃烧统燃料气体、石油在制品或油库贮罐保护气体与热处理保护气体的微压自动调节等场合。

Self operated micro (poor) pressure regulating valve (VTON) is an energy-saving product that does not require external energy. It compares the pressure changes of the medium in the process pipeline with the signal to balance the force of the regulated medium with the output force of the actuator, in order to achieve stable pressure and differential pressure values. The imported self operated micro (differential) pressure regulating valve is mainly used in situations where the pressure in front of the valve is less than 0.2MPa and the minimum usable pressure behind the valve is 5KP kilopascals. It is suitable for controlling the mixing ratio flow of two types of fuel gases in various industrial furnace combustion systems or for sealing oil systems in hydrogen cooled generator sets. At the same time, it can also be used for automatic control of pressure reduction, stabilization, or relief of various industrial gases.

The American VTON self operated micro (differential) pressure regulating valve adopts a balanced single seat valve, which can adjust the set value freely during operation. Therefore, it is suitable for micro pressure automatic adjustment of various industrial furnace combustion system fuel gases, petroleum in process products or oil storage tank protective gases and heat treatment protective gases.
