Pressure Relief Valve:SET AND FORGET!
FAV Pressure Relief Valves offer performance, reliability and flexibility of use in one easy to maintain, reliable product design. Our Instrument Safety Relief Valve are available in a variety of materials and end connections .They are highly durable and provide effective performance without any leakage.Safety Relief 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
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.

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
