Figure 10 and 15 Safety Valves

Cast Iron Safety Valves are ASME certified and available in sizes 3/4 x 1 to 3 x 3 inches and orifices .276 to 4.43 square inches for steam, air, vacuum, and non-hazardous gas service. These valves are suitable for pressures from 5 to 15 psig, 1 to 30 HG, and temperatures from -20 to 400 deg. F. They are also available with lifting lever and non-corroding aluminum bodies (15LC).

Figure 800 Safety Relief Valve

The Figure 800 meets ASME Section VIII for liquid, steam, air, and gas services. The valve features quick opening and short reclosing pressures while incorporating a fixed ring design that reduces maintenance costs and provides longer life. The standard Figure 800 comes with all stainless steel internals for improved corrosion resistance. A soft seat option provides tighter shutoff for those applications when the operating pressure is close to the set pressure of the valve. The Figure 800 is available in pressures to 900 psig and temperatures to 422°F. Additionally, the Figure 800 is suitable for Cryogenic Application down to -400°F.
