Product Description
This Automatic Liquid Flow Regulator Type FRVA regulates the liquid flow automatically for ammonia overfeed systems. It is a well-built, durable piece of machinery that regulates liquid flow..This Automatic Liquid Flow Regulator Type FRVA regulates the flow of liquid to the evaporator and guarantees a steady flow when changed. As a check valve, it also prevents backflow from the evaporator into the liquid line during pressure reversals that happen during hot gas defrost. In many pressure settings, it automatically makes up for differences.
Effortless and Accurate Liquid Flow ControlThe FRVA flow regulator is designed to automatically adjust and maintain desired flow levels without manual intervention. Its diaphragm type body facilitates self-setting flow adjustment, making it ideal for continuous process operations in water, oil, or chemical environments. The regulator reliably delivers zero leakage when closed, promoting efficiency and safety, and can be installed in either horizontal or vertical configurations to suit system layouts.
Outstanding Durability and Corrosion ResistanceBuilt with high-quality brass or stainless steel and finished in polished or powder-coated surfaces, the FRVA can withstand harsh, aggressive chemicals. EPDM or PTFE seals prevent degradation and ensure long-term, leak-free performance. The valve's robust design ensures a life span exceeding 100,000 operating cycles even under pressures from 0.2 to 10 Bar and temperatures from -10C to 80C.
FAQ's of Automatic Liquid Flow Regulator Type FRVA:
Q: How does the FRVA Automatic Liquid Flow Regulator adjust flow rates automatically?
A: The FRVA uses a precision-machined diaphragm mechanism that responds to system pressure, automatically regulating flow between 4 and 50 L/min without requiring manual adjustment. This self-setting function ensures consistent delivery for water, oil, or chemical media.
Q: What installation positions are supported by the FRVA regulator?
A: This regulator is designed for versatile installation and can be mounted in either horizontal or vertical positions, offering flexibility for different system configurations.
Q: When is maintenance required for the FRVA flow regulator and how is it performed?
A: The FRVA requires minimal maintenance due to its robust, corrosion-resistant construction. If servicing is needed, the regulator can be easily dismantled thanks to its user-friendly design. Routine inspections may be performed to ensure optimal performance, especially in high-frequency applications.
Q: Where can the FRVA regulator be used in terms of pipe compatibility and media type?
A: The FRVA is compatible with GI, SS, UPVC, and CPVC pipe materials and is suitable for liquid media such as water, oil, and chemicals. It is commonly used in automatic flow regulation systems for industrial, water treatment, and chemical processing applications.
Q: What are the primary benefits of using the FRVA flow regulator in aggressive liquid systems?
A: Key benefits include zero leakage when closed, high corrosion resistance for aggressive liquids, mechanical operation without power (no electricity required), and compliance with ISO 9001:2015 standards. Users also gain efficient, automatic flow control and extended durability exceeding 100,000 cycles.
Q: How does the FRVA handle varying pressures and temperatures during operation?
A: The regulator is designed for pressures from 0.2 to 10 Bar and temperatures from -10C up to 80C, making it suitable for demanding environments in both industrial and commercial applications.
