Brass Vertical Check Valve

Product Features

● Axially Guided Disc: The disc moves along the valve axis for stable opening and closing.
● Spring-Assisted Closing: Helps the valve close quickly when forward flow decreases.
● Brass Body Construction: Provides good corrosion resistance for compatible media.
● Compact In-Line Design: Requires limited installation space.
● Threaded Connection: Enables convenient installation in small-diameter piping systems.
● Automatic Non-Return Operation: Operates according to differential pressure without external power.
● Controlled Closing Action: Helps reduce reverse flow before full closure.
● Flow Direction Marking: The valve must be installed according to the arrow marked on the body.

Industry Applications

Industry Applications

● Building water supply
● Vertical risers
● Pump discharge pipelines
● HVAC circulation systems
● Agricultural irrigation
● Water treatment auxiliary systems
● Compressed air systems with compatible sealing materials

For vertical installation, the medium should normally flow upward. Suitability for downward flow or other installation orientations must be confirmed according to the specific internal construction.
