6、a.org. The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general, and the International System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benefits to USA use
7、rs of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and professional dealings with other countries. Toward this end, this Department will endeavor to introduce SI-acceptable metric units in all new and revised standards, recommended practices,
8、 and technical reports to the greatest extent possible. Standard for Use of the International System of Units (SI): The Modern Metric System, published by the American Society for Testing & Materials as IEEE/ASTM SI 10-97, and future revisions, will be the reference guide for definitions, symbols, a
9、bbreviations, and conversion factors. It is the policy of ISA to encourage and welcome the participation of all concerned individuals and interests in the development of ISA standards, recommended practices, and technical reports. Participation in the ISA standards-making process by an individual in
10、 no way constitutes endorsement by the employer of that individual, of ISA, or of any of the standards, recommended practices, and technical reports that ISA develops.

28、hrough NPS 26 (DN 650), of the clamp or pinch valve design incorporating clamp or pinch elements. 2 Purpose The purpose of this document is to aid users in piping design by providing installed face -to-face dimensions for control valves that incorporate clamp or pinch elements and have flanges that
29、mate with ANSI B16.1 Class 125 and/or ANSI B16.5 Class 150 flanges. This document also applies to handwheel-operated pinch valves, which have flanges that mate with Classes 125 and 150, but excludes solenoid-actuated valves and direct fluid-actuated valves. Due to the extensive variety in applicatio
30、ns for pinch valves, it is not reasonable to standardize on only one set. Some applications are better suited to a shorter face-to-face, whereas others need extra length. Users of pinch valves are advised to discuss with the pinch valve manufacturers based on their requirements, their unique process
31、 conditions, and the type of elastomer or rubber used. All face-to-face dimensions in this document have been applied successfully throughout industry.

36、e element clamp or pinch valve a valve consisting of a one-piece flexible element or liner installed in a body with the element or liner extending over the flange faces and acting as a gasket between the valve and connecting piping. Valves may be specified in any of the common face-to-face dimension
37、s shown in Table 1 in inches (in millimetres). 5.2 two-piece element clamp or pinch valve: a two-piece element clamp or pinch valve is a valve consisting of two flexible elastomeric elements or liners installed between a two-piece flanged body. The flexible elements or liners also extend over the fl
38、ange faces and act as gaskets between the valve and the connecting piping. 5.3 face-to-face: each of the face-to-face dimensions in Table 1 is to be applied to the installed length of the valve after installation into a piping system. The free length face-to-face dimension of a valve before installa
39、tion into a piping system may be slightly longer than dimensions shown in each of the tables. The free length face-to-face dimension of a pinch valve before installation into a piping system (known as the soft face-to-face dimension in pinch valves) is often longer than the dimensions in Table 1 to
40、allow for installed compression of the elastomeric liner face.
