What type of valve can be fitted on an NH3 drip leg?

A drain valve is appropriate for installation on an NH3 (ammonia) drip leg because it allows for the safe and efficient removal of condensate that may accumulate in the drip leg. NH3 is commonly used in refrigeration and industrial processes, and the presence of liquid ammonia in the drip leg needs to be managed to prevent issues such as corrosion or blockages in the system.

The drain valve provides a means to vent or drain this liquid ammonia safely, ensuring that the piping system remains operational and minimizes the risk of potential leaks or pressure surges that could occur if condensate is not regularly removed. Proper drainage is critical in maintaining the integrity and efficiency of ammonia systems, making the drain valve a vital component in such configurations.
