Description
ADCA PRV47 Pressure Regulator
The ADCA PRV47 pressure regulator is specifically designed for use with steam, compressed air, nitrogen, and other gases compatible with its construction materials. The PRV47 provides reliable and precise pressure regulation, making it ideal for installation in areas where pressure reduction is required across various industrial applications. With its high sensitivity, it ensures accurate control even in cases of fluctuations in inlet pressure or flow rate.
Usage Features:
- Suitable for saturated steam, compressed air, and other gases (Group 2) compatible with its construction (excluding oxygen).
- Ensures stable and reliable pressure regulation, enhancing the performance of your systems.
Dimensions:
- Ranges from 1/2” to 2”.
- DN15 to DN50.
