ICS 23.100.50                         PGD 36

Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 2) (First Revision) which is identical with ISO 5599-2 : 2001 'Pneumatic fluid power - Five-port directional control valves - Part 2: Mounting interface surfaces with optional electrical connector' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Fluid Power Systems Sectional Committee and approval of the Production and General Engineering Division Council.

In pneumatic fluid power systems, power is transmitted and controlled through a gas under pressure circulating within a circuit.

The various devices for gas distribution and control can be either mounted directly onto the piping, or mounted on interface surfaces to allow quicker dismantling and to promote equipment interchangeability.

Pneumatic directional control valves of the five-port, four-way type, as used on mounting interface surfaces complying with the requirements of this part of IS 15045, control the flow of compressed gas.

When the valve is electrically operated, it may be desirable to use an electrical connector at the interface of the valve body and base. Users of pneumatic valves benefit when this electrical connector is standardized, allowing easy electrical connection interchangeability between valves produced by different manufacturers.
