Steam Heated Regulators
RDVC Series
Introduction
RDVC Series Steam Heated Regulators are designed to heat fluids for analyzer systems, primarily to preheat fluids and prevent gas condensation or liquid evaporation. The unique design allows for easy disassembly, cleaning, and replacement of heat transfer components, reducing maintenance time and costs.
Features Heated Steam Regulators RDVC Series
◎ Low internal volume and high flow rate
◎ Convoluted diaphragm for improved regulation precision and extended service life
◎ Reinforced diaphragm improves sealing performance and extends service life
◎ Wetted metal components comply with NACE MR0175
