Book Description
This standard establishes minimum requirements for pilot-operated control valves of globe, angle, and wye body styles with various end connections in sizes from 1-1/2 through 60 in. (37.5 through 1,500 mm) in diameter, with water having a pH range from 6 to 9 and a temperature range from 40°F to 125°F (4.4°C to 52°C). The standard covers piston- and diaphragm-type valves suitable for a maximum steady-state fluid working pressure of 300 psig (2,070 kPa), a maximum steady-state differential pressure of 300 psig (2,070 kPa), and a maximum line velocity of 15 ft/sec (4.6 m/sec). 1.1.1 Body type and class. The valves described in this standard are provided in three body types (globe, angle, and wye) with various pilot-operating methods in pressure classes described as follows: 1.1.1.1 Angle body type. Classes 125, 150, 250, and 300; ASME flanges, National Pipe Thread (NPT) and grooved joint ends in sizes 1-1/2 to 60 in. (37.5 to 1,500 mm). 1.1.1.2 Globe body type. Classes 125, 150, 250, and 300; ASME flanges, NPT and grooved joint ends in sizes 1-1/2 to 60 in. (37.5 to 1,500 mm). 1.1.1.3 Wye body type. Classes 125, 150, 250, and 300; ASME flanges, NPT and grooved joint ends in sizes 1-1/2 to 60 in. (37.5 to 1,500 mm). Downloadable versions of current and historical standards are also available.
