Product Overview

The BV405S series electric regulating ball valve consists of a BV series electric actuator and a brass body regulating ball valve. It is primarily used in central air conditioning chilled/hot water and heating systems to precisely control the flow of cold and hot media as needed, preventing drastic temperature fluctuations and achieving real-time, accurate room temperature control. This regulating ball valve features an adjustable flow ratio, high reliability, long service life, and uses PTFE graphite-enhanced valve body seals with dual EPDM stem seals. It has an integrated built-in flow distribution disc, is resistant to reverse pressure differentials, and offers an equal percentage flow characteristic. High shut-off force of 1.4MPa, rated working pressure PN16, maximum pressure differential 0.35MPa. Equipped with manual override function for the actuator. Operating temperature range from -5 to 121°C, suitable for water, steam, or 50% glycol water.
