George McHugh and his family have been involved in the fire sprinkler industry since the founding of AGF, and the introduction of the AGF TESTANDRAIN valve more than 30 years ago. Currently serving as vice president of AGF Manufacturing, McHugh is responsible for the development, introduction and manufacture of specialized valves and unique products specifically designed for the fire sprinkler industry. AGF is involved in NFSA, NFPA, SFPE, ASPE and AFSA. McHugh is a strong proponent of domestic manufacturing and looks forward to serving the fire sprinkler industry and continuing the tradition of service started by his father, George McHugh III.
Pressure relief valves protect fire sprinkler system components by relieving excess system pressure from supply surges or temperature changes. Since the 2010 edition, NFPA 13: “Standard for the Installation of Sprinkler Systems” has required pressure relief valves to be installed on all wet pipe fire sprinkler systems. But picking the correct relief valve for a specific system does need a little preplanning.
How can engineers and contractors design wet fire sprinkler systems equipped to prevent corrosion and dry systems equipped to prevent freezing? That has long been a question central to code requirements and new product development.
