A-402-VA

The Continental NH3 A-402-VA and AA-402-VA safety relief valves are essential components in ammonia refrigeration systems, designed to ensure safe and efficient operation. This particular model is a 3/4 inch MPT threaded safety relief valve, with a pressure rating of 250 psi (1724 kPa).

The Continental NH3 A-402-VA and AA-402-VA safety relief valves are constructed from high-quality materials, including the body which is made of ductile iron and the trim which is made of stainless steel. This construction ensures durability and resistance to corrosion, making it suitable for use in harsh refrigeration environments.

The valve operates on a pilot-operated principle, with a pilot actuator that activates the main valve when the system pressure reaches a predetermined set point. The pilot actuator is mechanically linked to the main valve, which ensures a quick and reliable response time.

The safety relief valve is designed to release excess pressure from the system when the pressure exceeds the set point. This helps prevent overpressure situations that could potentially lead to system damage or safety hazards. The valve is also equipped with a pressure gauge, which allows for easy monitoring of the system pressure.

The Continental NH3 A-402-VA and AA-402-VA safety relief valves come with a factory-installed positioner, which allows for remote adjustment of the set point. This feature enables easy calibration of the valve to meet changing system requirements, ensuring optimal system performance.

The valve also features a self-cleaning mechanism, which helps prevent the accumulation of ice and other debris on the valve trim. This ensures that the valve remains functional even in the presence of contaminants in the ammonia refrigerant.

In summary, the Continental NH3 A-402-VA and AA-402-VA safety relief valves are reliable and robust components that play a crucial role in ensuring safe and efficient operation of ammonia refrigeration systems. With their durable construction, quick response time, remote adjustability, and self-cleaning mechanism, these valves offer peace of mind to system operators and help minimize downtime and maintenance costs.
