Butterfly & Check Valves for Secondary Water Supply Pump Rooms

The secondary water supply pump room serves as a pivotal component in ensuring consistent and reliable water delivery, particularly in high-rise buildings and remote areas where municipal water pressure is insufficient. This facility stores treated tap water in tanks and utilizes booster pumps to elevate water pressure, enabling it to overcome gravitational challenges and friction losses within vertical and extended pipeline systems. Equipped with essential components such as water pumps, storage tanks, valves, control systems, and disinfection devices, the pump room maintains the necessary pressure levels and water quality standards. The integrated operation of these elements ensures a continuous, safe, and hygienic water supply that meets the specific demands of elevated structures and distant users.

In secondary water supply pump rooms, butterfly valves play a crucial role in controlling and isolating water flow between pumps and storage tanks. These quarter-turn valves feature a rotating disc that, when turned, allows for quick and efficient shut-off or regulation of water flow. These butterfly valves are generally designed and manufactured in accordance with EN 593 and BS 5155, made from robust ductile iron and furnished with EPDM seats. Their compact design and ease of operation make them ideal for installations where space is limited and rapid response is necessary. By enabling maintenance activities without disrupting the entire system, butterfly valves ensure operational flexibility and safety. Additionally, their low pressure drop and high flow capacity contribute to the overall efficiency of the water supply system.

In the secondary water supply pump room, a swing check valve is installed on the pump’s discharge line to prevent backflow when the pump stops operating. This valve features a hinged disc that opens with forward flow and closes automatically when flow reverses, thereby protecting the pump and associated equipment from potential damage due to reverse flow. Additionally, swing check valves help maintain system pressure and prevent issues such as water hammer, contributing to the overall efficiency and longevity of the water supply system.
