The full lift threaded safety valve serves as a pivotal safety mechanism employed across diverse industries to safeguard critical equipment, intricate pipelines, and intricate systems from perilous overpressure situations.

The pressure rating of the valves covers ANSI CL150 to CL1500 and PN16 to PN260, allowing them to withstand a wide range of operating pressures.

 

 

1.Rapid Pressure Relief: The full lift design allows for quick and complete opening of the valve, facilitating rapid discharge of excess pressure from the system to prevent overpressurization and potential damage.

2.Simple Installation: The threaded connection of the valve enables easy and straightforward installation onto threaded outlets or fittings, reducing installation time and effort.

3.Cost-Effectiveness: These valves offer a cost-effective solution for overpressure protection, providing efficient operation and long-term reliability without requiring complex installation or maintenance procedures.

1.Ensure that the valve is installed in a vertical orientation, as specified by the manufacturer, to facilitate optimal performance.

2.Verify that the threaded outlet or fitting onto which the valve will be installed is clean, smooth, and free from damage.

3.Verify that the valve is the correct size and type for the intended application and operating conditions.

4.Carefully align the valve with the threaded outlet or fitting and hand-tighten the connection to prevent cross-threading.

5.Apply pressure to the system to simulate an overpressure condition and observe the valve's response, ensuring that it opens fully and relieves pressure as intended.
