scope:

This standard establishes minimum requirements for pilot-operated control valves of globe, angle and wye body styles with various end connections in sizes from 1½ in. through 60 in. (37.5 mm through 1,500 mm) in diameter, with water having a pH range from 6 to 9 and a temperature range from 40° to 125° F (4.4° 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).

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 classes described as follows:

Angle body type: Class 125, 150, 250, and 300, ASME flanges, National Pipe Thread (NPT) and grooved joint ends in sizes 1½ to 60 in. (37.5 to 1,500 mm).

Globe body type: Class 125, 150, 250, and 300, ASME flanges, NPT and grooved joint ends in sizes 1½ to 60 in. (37.5 to 1,500 mm).

Wye body type: Class 125, 150, 250, and 300; ASME flanges, NPT and grooved joint ends in sizes 1½ to 60 in. (37.5 to 1,500 mm).

Purpose

The purpose of this standard is to define the minimum requirements for pilot-operated control valves, including sizing considerations, design verification, testing, delivery, handling, and storage.
