General Specifications
The document describes a 3-way ball valve with butt weld ends, available in two types: T-port (Type 1611) and L-port (Type 1711). The valve dimensions range from DN8 to DN100, with pressure ratings varying by size: DN8 to DN25 at 69 bar, DN32 to DN50 at 55 bar, and DN65 to DN100 at 41 bar. The material used is stainless steel, and it features an ISO 5211 top flange.

Options
The valve can be constructed in 4- and 5-way configurations and can be connected via thread, socket weld, or flange. Various materials are available for seat rings and packing.

Material Composition
The valve components are primarily made of stainless steel AISI 316, with some parts using AISI 304 and AISI 301. The seat is made of PTFE/RTFE, and the joint gasket and stem seal are PTFE. The gland packing is composed of 75% PTFE and 25% glass fiber.

Dimensions and Torque
The document provides detailed dimensions and torque requirements for each valve size, from DN8 to DN100. For example, a DN8 valve requires 9.6 Nm of torque and weighs 1.4 kg.

Flow Diagram and Pressure/Temperature Graph
The document includes a flow diagram and a pressure/temperature graph, indicating the operational limits of the valve under various conditions. It notes that torque figures include a 30% safety factor, with adjustments needed for different media types: +15% for dry air and demineralized water, +30% for sludge and abrasive media, and -15% for lubricating media.
