3 Range and Index Regular Pattern Short Pattern Venturi Pattern Full Port pattern as per API 6D is available. Valves not shown in the table will be considered against specific requirements Class NPS 3000 Inch mm S R S R V R V R R V R V V 1/2 15 3/ / VETZ Lubricated Type Plug Valves are available in Regular, Short, Venturi Pattern or Full port. These terms are defined in BS 5353, API 6D and APl 599. The different patterns vary as regards end to end dimension and port area for a given size of valve. Regular Pattern valves have the largest port area. Short Pattern valves have a reduced port area as a consequence of their compact face to face dimensions which are identical to those for wedge gate valves. Venturi Pattern valves have a reduced port area and a flow path approximating a venturi shape to aid pressure recovery face to face and end to end dimensions conform to ANSI B16.10 and BS WENZHOU VETZ VALVE CO., LTD 1

4 Figure Numbering A familiarity with our figure number system is not necessary when specifying or ordering our valves. Providing a full description of the valve is given. Our sales office will translate this into a figure number. A full description of the valve would begin with VETZ Lubricated Type Plug Valve Pressure Balanced Valve and would then go on to give size, pressure rating, flanging details etc. We give an example below in order to illustrate a typical figure number. but if a fuller explanation is required please feel free to contact us by qa-dept@ways-valves.com.

These durations will be adhered to unless a different specification is required against a particular order. Hydrostatic tests of long duration require that the valve be given special attention to facilitate pipeline testing.the same duration for BS6755, GB/T13927 & ISO ISO5208 has no this requirement which is cited from BS The same duration for JB/T9092, API600 & API API 6D also requires a 5.5 bar(80 PSIG)air test on the seat for the same duration.

8 Installation, Marking, and Identification Marking and identification of VETZ steel valves conforms to ASME B16.34 and MSS-SP-25. It is important to properly identify valves in service to allow for the ordering of replacement parts or address questions or concerns relating to our products. Body markings and information shown on the identification plate helps to properly identify valves, allowing timely and accurate responses to such inquiries. Integrally cast body marking data includes the following information and helps to provide traceability: WAYS logo Pressure class Valve size The grade of material (i.e. WCB for carbon steel) Heat number on body and bonnet (cast or stamped) Series Number (Stamped on the edge of end flange) The body markings are supplemented by a nameplate which, depending on valve type and size, is mounted in the most practicable position. Nameplates bear the following information: Fig Number Valve size Body material Disc material Stem material Seat and trim material Pressure and temperature rating WENZHOU VETZ VALVE CO., LTD SIZE STEM SEAT DESIGN SER.
