WATTS® Dual Check Backflow Preventer With Intermediate Atmospheric Vent, 9DM2 Series, 3/4 in Nominal, Female Union Connection, 25 psi Adjustable, 175 psi Working Pressure, Forged Brass Body, 33 to 250 deg F, Dimensions: 4-1/2 in L x 2-9/16 in H
- It prevent the reverse flow of hot or cold polluted water from entering into the potable water supply
- It consists of a brass body with stainless steel internal parts, integral strainer and two durable, tight-sealing, rubber check valves
- For continuous pressure, non-health hazard applications in smaller supply lines
- It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing
- A secondary check valve utilizes a rubber disc to metal seating
- In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system
- True line sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling
- Maximum flow at low pressure drop
- Furnished with union connections to facilitate removal and replacement for maintenance
- Compact for economy combined with performance
- Design simplicity for easy maintenance
- Can be installed vertically or horizontally
