Conrader safety valves are designed to protect unfired pressure vessels and systems from over pressure in compressed air and gas applications. The valves are not deemed "Lead Free". The soft seat safety valve (SRV-Series) has an elastomer seal. Set Pressure Tolerance: +2 psig up to and including 70 psig, +3% of set pressure greater than 70 psig. Operating Temperature Range: -65 degrees Fahrenheit to 400 degrees Fahrenheit. Materials of Construction: Seat, Cap, Piston: ASTM B16 Brass Spring: 17-7 Stainless Steel Seal: Silicone or Viton. Certifications: ASME Boiler & Pressure Vessel Code Section VIII Division 1 CSA B51 Boiler, Pressure, Vessel, and Pressure Piping Code
