SECTION 15100
VALVES
PART 1 - GENERAL
1.1 RELATED DOCUMENTS
A. Drawings and general provisions of Contract, including General and Supplementary Conditions
and Division 1 Specification sections, apply to this section.
1.2 SUMMARY
A. This section includes general duty valves common to most mechanical piping systems. Special
purpose valves are specified in individual piping system specifications. Valve tags and charts are
specified in Divisions 15 Section "MECHANICAL IDENTIFICATION."
1.3 SUBMITTALS
A. Product Data
Include body materials, valve design, pressure and temperature classification, and connection
details, seating materials, trim material and arrangement, dimensions and required clearances,
and installation instructions.
1.4 QUALITY ASSURANCE
A. Single Source Responsibility: Comply with the requirements specified in Division 1 Section
"MATERIALS AND EQUIPMENT," under "Source Limitations."
B. American Society of Mechanical Engineers (ASME) Compliance: Comply with ASME B31.9 for
building services piping and ASME B31.1 for power piping.
C. Manufacturers Standardization Society of the Valve and Fittings Industry (MSS) Compliance:
Comply with the various MSS Standard Practices referenced.
1.5 DELIVERY, STORAGE AND HANDLING
A. Prepare valves for shipping by ensuring valves are dry and internally protected against rust and
corrosion. Protect valve ends against damage to threads, flange faces, and weld-end preps. Set
valves in best position for handling. Set globe and gate valves closed to prevent rattling; set ball
and plug valves open to minimize exposure of functional surfaces; set butterfly valves closed or
slightly open; and block swing check valves in either closed or open position.
B. During storage do not remove valve end protectors unless necessary for inspection; then reinstall
for storage. Protect valves from weather. Store valves indoors. Maintain valve temperature
higher than the ambient dew point temperature. If outdoor storage is necessary, support valves
off the ground or pavement in watertight enclosures.
C. When handling use a sling to handle valves whose size requires handling by crane or lift. Rig
valves such to avoid damage to exposed valve parts. Do not use hand wheels and stems as
lifting or rigging points.
