Air Main Charging Valve

 

AMCV

Compressed air dryers and filters are designed and rated to treat specified volumes of air at specific conditions. If system pressure is not present 24 hours a day, 7 days a week, air moves through clean air treatment equipment at unusually high velocity when the system is re-started. Until full operating pressure is reached, dryers and filters will not work to specification resulting in contaminants being swept downstream.

Air main charging valve

Kaeser's Air Main Charging Valve prevents excessive velocity by automatically opening and closing to maintain a safe pressure in the supply side of the air system while charging the main distribution piping in the minimum possible time. The AMCV minimizes the exposure time of air treatment to high velocity air, thereby extending its service life.

Air Main Charging Valve Components and their Functions

The Air Main Charging Valve consist of three main components: a pressure switch which is adjusted to the desired set point, a 5-way solenoid control valve combined with adjustable nozzles precisely controls to eliminate swings in pressure and velocity, and either a ball valve or butterfly valve to create minimal pressure drop and provide for manual override. Kaeser offers a variety of systems to meet you facility's specific requirements.

Three System Configurations


air main charging valve - ball valve   Ball Valve
This unit features an electro-pneumatic, full-bore valve and is ideal for air systems with 1-inch, 1 1/2-inch, and 2-inch nominal diameter air lines. The pressure is adjustable up to 200 psig. Maximum operating temperature is 150°F.
air main charging valve - butterfly valve   Butterfly Valve
This unit features an electro-pneumatically driven, insertion-type butterfly valve and is perfect for large air systems with pipe diameters between 2 and 8 inches. The pressure is adjustable up to 200 psig. Maximum operating temperature is 150°F.
High Temperature Butterfly Valve
This unit features an electro-pneumatically driven, insertion-type butterfly valve and is perfect for large air systems with pipe diameters between 2 1/2 and 8 inches for use after externally heated dryers. The pressure is adjustable up to 232 psig with a maximum operating temperature of 400°F.
