Organization: (NFPA)
Publication Date: 14 February 2002
Status: active
Page Count: 83
scope:

1.1 This standard includes mounting surfaces for the following:

- non-return (check) valves;

- compensated flow control valves;

- directional control valves;

- pilot operated non-return (check) valves;

- pressure control valves;

- pressure relief valves;

- sequence valves;

- throttle valves; and

- unloading valves.

This standard includes the following dimensional criteria:

- minimum surface width and length dimensions

- sizes and locations of pods;

- sizes and locations of tapped holes for mounting fasteners; and

- sizes and locations of dowel or rest pins where required.

This standard provides the following general criteria:

- surface roughness and flatness;

- indication of appropriate radii; and

- indication of tolerances where pertinent.

This standard only applies to the dimensional criteria of products manufactured in conformance with this standard. It does not apply to their functional characteristics. The maximum working pressure for subplates and manifold blocks with this mounting surface shall be supplied by the manufacturer.
