Resources
WATTS® Check Valve Backflow Preventer Assembly, 9D Series, 1/2 in Nominal, FIP Connection, 175 psi Pressure, Bronze Body, 33 to 250 deg F, Dimensions: 4-15/16 in L x 2-9/16 in H
Series 9D is specially made for smaller supply lines and ideally suited for laboratory equipment, processing tanks, sterilizers, dairy equipment and similar applications. It is particularly recommended for boiler feed lines to prevent backflow when supply pressure falls below system pressure.
- 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
- Stainless steel internal parts
- 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
