The DC1611 top guided single seat regulating valve has the characteristics of small volume, simple structure, and wide application. Suitable for non cavitation liquids and steam, gas, and other environments with noise within the specified range. The internal components of the DC1621 sleeve guided single seat regulating valve are quick detachable structures. If the guiding sleeve is replaced with a porous structure, it can withstand higher pressure differentials and is very easy to maintain on site.
