Application
· Control valves applied to occasions where there is no external energy on site, the pressure difference Is very low, and automatic pressure stabilization control is required
· Nominal diameter: DN20 ~ DN150, NPS 3/4" ~ 6"
· Nominal pressure: PN16, ASME CL150
· Medium temperature: -40° C ~ +80° C
Features
· Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials
· No external energy required, with the pressure difference between one or two media being adjusted automatically, so as to maintain a constant pressure difference
· Extremely sensitive actuator elements, being capable of sensing very small pressure changes
· Convenient pressure regulation, allowing adjustment of the setting value without interrupting manufacturing
