Steam Safety Valve India

Feature of Steam Safety Valve

• Set Pressure: The pressure at which the valve starts to open and release steam is known as the "set pressure" or "pop-off pressure." It is carefully calibrated to the system's design specifications and safety standards.
• Blowdown: The difference between the set pressure and the pressure at which the valve reseats is referred to as "blowdown." Blowdown ensures that the valve closes properly once the pressure drops, preventing any steam leakage.
• Sizing: Steam safety valves must be appropriately sized for the system they are protecting. Factors such as steam flow rate, pressure, temperature, and the specific application influence the valve's size and capacity.
• Installation: Proper installation of safety valves is crucial. They should be mounted vertically with the outlet directed away from personnel and equipment. Piping leading from the valve should also be properly sized and installed.
• Maintenance: Regular inspection and maintenance of steam safety valves are essential to ensure their proper functioning. Valves can become corroded or blocked over time, so they should be tested and serviced according to relevant standards and regulations.
• Codes and Standards: Steam safety valves are designed and manufactured in accordance with various industry standards and codes, such as ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code. These standards ensure that the valves meet specific safety and performance requirements.
