Watts 0061888 Details
This Watts 9D series 3/4" dual check valve with an intermediate atmospheric vent is designed for smaller supply lines. It's ideal for laboratory equipment, processing tanks, sterilizers, and dairy equipment, and it's great for boiler feed lines to prevent backflow when the supply pressure falls below the system pressure. If there is fouling of the downstream check valve, any leakage is vented to atmosphere through the vent port, safeguarding the potable water system. This valve has 3/4" female union inlet and outlet connections with a 1/2" threaded drain connection. It features a bronze body with stainless steel working parts, integral strainer, and durable rubber discs.
This dual check valve is suitable for use on hot or cold water equipment, and it can be used under continuous pressure. Thanks to its true line-sized construction, this valve allows the check modules to open further to allow dirt and debris to pass more freely, reducing check fouling. It features a compact design and a maximum flow at low pressure drop. Plus, the simple design allows for easy maintenance, and it can be installed vertically or horizontally. It has a temperature range of 33 to 250 degrees Fahrenheit and a maximum working pressure of 175 PSI with a minimum required pressure of 25 PSI.
