The body and component parts of valves shall be designed and manufactured to perform their intended functions reliably so that, in the course of handling, installation, normal operation or maintenance,damage that would prevent their continued conformance with this Standard does not occur.
Unless otherwise specified, all valves shall be provided with a minimum of two parallel wrench flats.
NOTE Guidelines for the acoustic evaluation of valves are given in Appendix D.
When tested in accordance with Appendix E, the valves under test shall be capable of withstanding,without permanent distortion, the applied torque, as appropriate. This test is not applicable where elastomeric seals are used on connections for assembly of combination valve bodies.Under the conditions of this Clause, reconditioned and re-used components may be used to manufacture valves to this Standard. The main component that would be reconditioned is the valve body and reconditioning would normally be undertaken on the valve seat. Other components may be considered for reconditioning where, after the reconditioning, the quality of the component will meet the requirements of this Standard.
The following procedures shall be adhered to:
(a) The used valve shall be totally disassembled.
(b) The non-re-usable components including the critical components, as defined in this Standard,shall be discarded.
(c) All components to be re-used shall be thoroughly cleaned, inspected and/or tested to determine whether they conform to the manufacturer’s specification.
(d) Components that do not conform to the manufacturer’s specification shall be reconditioned or discarded.
(e) Replacement components shall be selected as required.
(f) The valve shall be assembled to the manufacturer’s specification.
Remanufactured valves shall be individually packaged. The words“THIS IS A REMANUFACTURED VALVE AND CONTAINS RECONDITIONED COMPONENTS” shall be clearly visible on or through the packaging. These words shall be in a prominent position, immediately adjacent to the model number or name and with a minimum text height of 8 mm.AS 1357.1 pdf free download.
