Valve With Air Pressure Switch For Dry Pipe Sprinkler System

SANJING FIRE valve with an air pressure switch is a type of valve used in a dry pipe sprinkler system to control the flow of water into the system and monitor the air pressure. The valve is typically installed at the main control valve and is designed to prevent water from entering the dry pipe until the system is activated.

The valve with air pressure switch consists of a valve body, a clapper assembly, and an air pressure switch. The clapper assembly is designed to prevent water from entering the dry pipe until the system is activated. The air pressure switch is connected to a monitoring system that can alert personnel to any changes or abnormalities in the system.

When the dry pipe sprinkler system is activated, the air pressure in the system drops, causing the clapper assembly to open and allow water to flow into the piping. At the same time, the air pressure switch detects the drop in air pressure and sends a signal to the monitoring system, alerting personnel to the activation of the system.

Regular maintenance and inspection of the valve with air pressure switch is important to ensure proper function and prevent leaks or other failures that could compromise the safety of the system. The valve should be checked regularly to ensure that it is in good working order, and any problems or malfunctions should be addressed promptly.
