Honeywell 51442 1/2" NPT Dual Check Intermediate Vacuum Breaker.

1/2" NPT. DOUBLE CHECK VACUUM BREAKER

The Honeywell 51442 1/2" NPT Dual Check Vacuum Breaker has a button release design. This dual check vacuum breaker is manufactured in the United States. The vacuum breaker measuring 0.5 x 3 x 3.5 inches weighs 4 ounces. The vacuum breaker from Honeywell can be used for hot or cold water or steam applications, with a temperature range of 30 to 250 degrees Fahrenheit.

The Honeywell 50414 1/2" NPT Dual Check Vacuum Breaker with Hose Barb is for use in commercial, sanitary, and various light duty applications. The unit fits on pipe size 1/2" NPT and offers three main functions: quick shut off, pop-free action and vacuum or blow-off capability.

The Honeywell 1/2" NPT Dual Check Vacuum Breaker is designed to ensure a positive shutoff under pressure with no leakage. The vacuum breaker has an adjustment screw to control the amount of flow through the two-way valve and it comes with Teflon stop fittings to reduce friction and noise. This check valves vacuum breaker helps prevent "flashback" that can cause serious damage in commercial applications.

This Vacuum Breaker has a 1/2" NPT female inlet (gas source) and male outlet (in the house). It is a double check vacuum breaker but will also work as a vacuum breaker. This is not a ball valve, it shuts off gas flow. All housing units need to be on the same level to prevent product failure.

The NPT size on this double check vacuum breaker can handle a much larger flow of water. This is particularly useful when connecting multiple fixtures to the same line, such as a washing machine and dishwasher.

Interchangeable with most conventional vacuum breakers and can be installed in the same valve body. Vacuum breakers in series are used to protect against gross leakage and to limit the pressure at which flow will stop. The double check feature can be interrupted by an intermediate check vavle or diaphram seperation valve to give added protection against gross leakage. Double check valves are also known as Double Check Diaphramatic Vacuum Breakers Double Check Diaphragm Seperation Valve

This dual check vacuum breaker allows you to use different size piping at the same time by providing separate check valves for each opening. The dual check design requires a greater pressure differential to open the second check valve compared to a single check design. This means that more accurate and reliable pressure settings can be achieved, which is ideal for applications like sterilization equipment.
