ISO 7790:2013 PDF

Scope: This International Standard specifies clamping dimensions offour-port modular stack valves and four- port directional control valves, sizes 0203, 05, 0708, and 10, on mounting Surfaces. The dimensions and Sizes conform to ISO 4401 so as to _ ensure interchangeability of these valves and to reduce the number of fixing devices to be used. It applies to clamping dimensions of four-port modular stack valves and four-port directional control valves which represent current practice. They are generally applicable to industrial equipment.
