Product Overview

Air valves perform two important functions in a piping system, They maintain system design efficiency and provide system protection. System efficiency is maintained by venting air via the air valves from the system than can restrict flow and increase pumping costs, Protection is provided by exhausting and admitting air throught the air valves during system operations including star-up, shutdown, and critical condictions such as power failures or line breaks, The exhausting and admitting of air during these condictions will reduce the potenctial for destructiv surges and water hammer normally associated with uncontrolled air or vaccum condiction within the piping systes. When liquid is pumped through the system at startup, the initial air inside the piping is pushed into the air vent by the pressure of the flow, thefloat remains in the lower part of the air vent, allowing the valve to remain open and the continuously discharge air, After the initial air venting, liquid flows into the air vent, The float ries with rising liquid and loses the valve
