Safety Valve:SET AND FORGET!
FAV Safety Valve offer performance, reliability and flexibility of use in one easy to maintain, reliable product design. Our Instrument Safety Valve are available in a variety of materials and end connections .They are highly durable and provide effective performance without any leakage. Safety Valve has come with a wide variety of port sizes, end connections, style, and temperature and pressure tolerance.
Pre-Calibrated Design or Range Setting
We give options of Pre-Calibrated Design or Range Setting for our Safety Valve
In Pre-Calibrated Design the Safety Valves are calibrated as per your required set pressure . Even on continuous usage our Safety Valves opens up at the set pressure . Our high tensile spring specially fabricated ensures this.
In Range Setting option we give you a lower limit and upper limit of Pressure . You can manually set at required range using the screw at the top.
The primary purpose of a Safety Valve is the protection of life, property and environment. A Safety Valve is designed to open and relieve excess pressure from vessels or equipment and to reclose and prevent the further release of fluid after normal conditions have been restored.
A Safety Valve is a safety device and in many cases the last line of defence. It is important to ensure that the safety valve is capable to operate at all times and under all circumstances. A Safety Valve is not a process valve or pressure regulator and should not be misused as such. It should have to operate for one purpose only: overpressure protection.
REASONS FOR EXCESS PRESSURE IN A VESSEL
There are a number of reasons why the pressure in a vessel or system can exceed a predetermined limit. The most common are:
• Blocked discharge
• Exposure to external fire, often referred to as “Fire Case”
• Thermal expansion
• Chemical reaction
• Heat exchanger tube rupture
• Cooling system failure
