1 CATALOGUE AUTOMATIC CONTROL VALVES 00

2 INTRODUCTION DOROT AUTOMATIC CONTROL VALVES is pleased to present the latest edition of their catalogue. This new catalogue includes new models as well as modifications of previous products. The updated information in this edition invalidates the data of the previous edition. This catalogue does not replace other technical publications such as the design manual which is available from DOROT. We are confident that you will be able to use this catalogue as a convenient guide for choosing among the wide range of DOROT products. The aims of the catalogue are: To enable the user to easliy select the valve model which best suits his/her requirements, being fully aware of the hydraulic conditions of his/her network and the required performance of the control valves. To create a "common language" between the customer and the factory in order to avoid confusion caused by the wide range of products, structural versions, control modes, materials etc. The catalogue is divided into sections, each one dedicated to a group of products. The information included in each section is the essential data required for designs and valve selections, made by consulting engineers, dealers, and users of water control networks. Sections A,B,C,D and E include: A general description of the specific group of valves, with pictures of the various models. The hydraulic characteristics of the valves in each section. A model selection table, listing all the standard models and sizes available in the group. Note that although production in DOROT is according to the metric system, the valve size code is in imperial (inches) dimensions and the relevant metric dimensions are also included. A schematic diagram featuring all the various components of the valve (including optional units). All the components are numbered, to facilitate the ordering of spare parts, or the valve's conversion into an optional version. An "ordering guide" which explains how to specify the chosen model. The control functions are listed in section F. Basic explanations of each function, a list of valve models which may perform the specified function, and the pilot valve used, are found in this section. Please note that the standard features of each model will be supplied with the product, unless specified otherwise in the confirmed order. The pilot valves and accessories are listed in section G. Information on the operating conditions and spare parts is found in this section. The "General Data", (section H) at the end of the catalogue, supplies details regarding conditions that are not standard, to assist the user. 0 0 II

3 BASIC R METAL VALVES S,, S,,, DESCRIPTION The direct-sealing diaphragm Valves are operated by pipeline pressure or by air pressure: (which is equal to the pipeline pressure). The reinforced rubber diaphragm seals the water passage when the line pressure reaches the valve's control chamber. Relieving the pressure from the control chamber causes the valve to open. The valve's only moving part is its diaphragm: no shaft, seals, or bearings are located within the water passage. A spring above the diaphragm ensures "valve closure" regardless of pressure level or flow conditions.

10 R PLASTIC VALVES DESCRIPTION The direct-sealing diaphragm valves are operated by line pressure. The reinforced rubber diaphragm seals the water passage when line pressure reaches the valve's control chamber. Relieving the pressure from the control chamber, to the atmosphere or to downstream, causes the valve to open. The valve's only moving component is its diaphragm; no shaft, seals, or bearings are located within the water passage. The valve is made of sturdy, high-quality materials. It is produced in a number of structurally different versions (throttling, built-in solenoid operator, etc), with a wide range of control functions (manual activation, pressure control, etc).
