SURGEx S20-A NPT Stainless Steel Bellows Water Hammer Arrestor DN20 3/4 NPT

SURGEx S20-A is a size A, pre-charged surge pressure absorber (also called Water Hammer Arrester (WHA) or surge arrester). The SURGEx-S series is fabricated from stainless steel grade 304 as standard and is fitted internally with stainless steel bellows. The end connection of SURGEx-S20-A is a male threaded size ¾” according to NPT. The SURGEx-S series can withstand pressures up to 400 PSIG (27.6 BAR) and has a temperature range from -100°F to 300°F (-73°C to 149°C).

OPERATION:
SURGEx-S series water hammer arresters use stainless-steel bellows as the main component to absorb the shock waves caused by water hammer. When a water hammer occurs, the bellows compresses as water rushes into the arrester, creating a cushioning effect that absorbs the pressure surge. As the water flow slows down and pressure stabilizes, the bellows returns to its original position, ready to absorb the next water hammer.
