Cast Iron and Aluminum Safety Valve

Applications

Figure 15 valves are high capacity safety relief valves for over-pressure protection of low to medium pressure, high volume blowers and compressors, bulk hauling trailers, pneumatic conveying equipment, air pollution control equipment, dryers, dust collectors and similar pneumatic equipment.

Sizes/Ratings

Available in seven sizes ranging from 3/4" x 1" to 3" x 3", connections are male NPT screwed inlet and female NPT screwed outlet. The cast iron body is rated at 60 PSIG at 400°F. Set pressures range from 5 to 15 PSIG. For setting over 15 PSI, please check factory.

Applicable Codes

Figure 15 safety relief valves are non-ASME Code valves in all sizes except 2" x 2-1/2". The 2" x 2-1/2" Figure 15 Safety relief valve meets the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII. Capacities for the 2" x 2 -1/2" valve are certified by the National Board of Boiler and Pressure Vessel Inspectors for set pressures 15 PSIG and above. All Figure 15 valves are approved and registered in every Province in Canada in accordance with C.S.A. B-51 under Canadian Registration No. 02636. 1 through 0.

Features

The Figure 15 valve features tight shutoff, sharp popping and closing action and a high degree of repeatability. The valve inlet and body are one integral casting assuing proper alignment of disc, seat and spindle for smooth action. The bronze disc is guided by a brass guide which in turn is held in place by a zinc plated wave spring. The entire assembly is contained by a combination bonnet/compression screw. The simplicity of the design means dependability and low cost. Standard Figure 15 valves are equipped with lifting levers (required by ASME Code, Section VIII for air service) or screwed cap (Figure 15A).
