NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 6264:1998 ‘Hydraulic fluid power —Pressure-relief valves — Mounting surfaces’ issued by the International Organization for Standardization(ISO) was adopted by the Bureau of Indian Standards on the recommendations of the Hydraulic FluidPower Systems Sectional Committee and approval of the Medical Instruments, General and ProductionEngineering Division Council.

This standard was first published in 1994 by adopting ISO 6264:1987 ‘Hydraulic fluid power— Pressure-relief valves — Mounting surfaces’ under dual numbering system. The ISO Standard has since beenrevised as ISO 6264:1998. To align the standard with international practices, the sectional committee,dealing with the subject, decided to revise IS 14150:1994 by adopting ISO 6264:1998 as IndianStandard under dual numbering system.

In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressurewithin an enclosed circuit. Hydraulic valves are typical components in such systems. These devicescontrol the flow direction, pressure or flow rate of liquids in the enclosed circuit.

The text of the ISO Standard has been approved as suitable for publication as an Indian Standardwithout deviations. Certain conventions are, however, not identical to those used in Indian Standards.

Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they shouldbe read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker in the International Standard while in IndianStandards, the current practice is to use a point (.) as the decimal marker.

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their places are listedbelow along with their degree-of equivalence for the editions indicated:

2, The dimensions specifying the area within the chain thick lines are the minimum dimensions for the mounting surface. Thecorners of the rectangle maybe radiused to a maximum radius, rm~X,equal to the thread diameter of the fixing screws.Along each axes the fixing holes are at equal distances to the mounting surface edges.

3) This dimension gives the minimum space required for a valve with this mounting surface. The CfimenSiOn k3 ak?O the

minimum distance from centreiine to centreiine of two identical mounting surfaces placed on a manifold block.



NOTES

1 The supplier shall stipulate the maximum working preasure for subplates and manifold blocks.

Review of Indian Standards

Amendments are issued to standards as the need arises on the basis of comments. Standards are also

reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that

no changes are needed; if the review indicates that changes are needed, it is taken up for revision.

Users of Indian Standards should ascertain that they are in possession of the latest amendments or

edition by referring to the latest issue of ‘BIS Catalogue’ and ‘Standards: Monthly Additions’.
