Under Development : Launching Soon !!

Cage Type Low Noise - High Pressure Gas Regulator    Model : HNV


HNV high pressure gas regulator is developed to reduce a nuisance noise generated where the depressurization at the governor station. Three steps perforated cage is adopted as the depressurizing mechanism to achieve the low noise operation.
Besides, HNV, which is composed of fewer parts in comparison to the current commercial products, improves the maintenance ability because of the compact size with lighter weight. Moreover, the parts of trim do not need the special tools for maintenance and all works can be carried out from the top end.
Actuating portion adopts the fabric reinforced NBR diaphragm to achieve the high operability, stability and compact design.
HNV can completely fulfill the customer’s requirement for single step depressurization from the high pressure main grid to the middle pressure sub grid or the end users such as power plant.
