T/CAMETA 001104-2025 Y-shaped multi-channel bottom ball valve
Basic Information
Scope
This document defines the terms and definitions of Y-type three-channel (bottom) ball valves, specifies the structural types and models, materials, technical requirements, inspection rules, ordering requirements, marking, packaging, and supply, as well as installation, operation, and maintenance of Y-type three-channel (bottom) ball valves. It describes the test methods for Y-type three-channel (bottom) ball valves, and is applicable to the bottom discharge, drainage, and sampling operations of reaction vessels, storage tanks, and other pressure vessels using Y-type three-channel (bottom) ball valves. The nominal pressure range of Y-type three-channel (bottom) ball valves is PN2.5~PN25 or class 125~class 150, and the nominal size is DN15 (NPS?)~DN300 (NPS12), with a flange connection to the tank bottom.
