SURGEx S20-A is a size A, pre-charged, surge pressure absorber (also called Water Hammer Arrester (WHA) or surge arrester. 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 male threaded size ¾” according to NPT. SURGEx-S series can withstand pressures up to 400 PSIG (27.6 BAR) and 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.

      Good content, very small print and photos
      Format: Paperback
      Get a magnifying glass… the print is tiny. They must have made this book to be a large hard cover because both the print and the photos are so small in paperback. Content looks decent. It’s a gift for my grandson who will probably spend more time with the photos than the reading anyway and his eyesight is better than mine. :D
