Automatic Flush Valves from Hydrotek

Hydrotek's standard features are often "options" on other manufacturer's auto-flush valves. If you want one of the best, Hydrotek is an excellent choice. One of the best advantages of the Hydotek Automatic Flush System is its flexibility; the flush volume for these valves is adjustable by changing the dip switch settings. Using the table and instructions provided, you can change the volume from 0.5 to 5.0 gallons per flush in increments of 0.5 gallons, limiting the number of valves needed for maintenance to have on hand. The retro-fit kits can also be used to convert existing Delany, Sloan and Zurn manual flush valves to hands free flush valves.
