Description:Performance: 1) Tolerance of set pressure: ≤±3% 2) Overpressure: ≤10% 3) Blowdown: ≤15% 4) Permeability: in compliance with API527 standards for air permeability Structure characteristics: 1) Compact structure, beautiful outer appearance, precision castings, and smooth surface 2) The valve's seat and body are separable, which enables the valve seat to be polished to guarantee air permeability and be easy to disassemble for repair and maintenance 3) The reasonable designed pair of disc holder and adjusting ring is convenient for adjustment. They can fully open the security valve in a short period and meanwhile make a timely return, which generates ideal open and close pressure difference 4) The sealing surfaces of the valve seat and valve clacks are welded with diamond-based rigid alloys, which will promote the valve's air permeability, anti-wear and anti-corrosion, and prolong its service life 5) Balanced back pressure relief valve is made of bellows for military use, which can eliminate the affect of back pressure on set pressure and quarantine the toxicant medium to prevent the contamination inside the valve 6) Twice 24-hour constant temperature treatment to key parts and spring will ensure their stable rigidity and normal opening of the valve 7) Compression test to valve, valve seat and other pressure parts will ensure safety and reliability during later application
