General Specifications
The 3-piece cryogenic ball valve, Type 1380, is designed for dimensions ranging from DN15 to DN100 with pressure ratings of PN137 for DN15-DN50 and PN69 for DN65-DN100. The valve is constructed from materials CF8M and CF3M, with connections available in BSPP thread or butt weld. It adheres to DIN3202 M3 S13 for face-to-face dimensions and ISO 5211 for mounting flanges. The operational temperature range is from -196°C to +200°C, and it can be operated manually or with pneumatic or electrical actuators.

Options
Additional dimensions available include DN8, DN10, and DN125, with connection options for flanged and socket weld.

Materials and Components
The valve consists of various components including a CF8M body, CF8M/CF3M end caps, a CF8M ball, and a 17-4 PH SS antistatic stem. Other materials used include PCTFE (KEL-F) for ball seats and stem packing, AISI304 for various nuts, bolts, and handle components, and Grafoil for body seals.

Dimensions
The document provides detailed dimensional data for each valve size, including outer diameter (OD), core diameter (CD), inner diameter (ID), Kv values, torque requirements at different temperatures, and various length and height measurements. For example, the DN15 valve has an OD of 15.0 mm, a CD of 21.3 mm, and an ID of 22.0 mm, with a Kv of 16.3 Nm3/h and torque of 11.8 Nm at -196°C.

Pressure and Temperature Ratings
The pressure and temperature ratings vary based on the valve size and connection type, with specific ratings provided for thread ends, socket weld, and butt weld connections.
