Introduction

In the pneumatic system, power transmission and control in the pressure of the gas loop conducted.

Various devices for gas distribution and control can be installed directly in the pipeline or mounting surface, the mounting surface can be achieved faster Speed \u200b\u200bdetachable and interchangeable purposes.

Pneumatic control valve installed in a five-way direction of the mounting surface of the role is to control the flow of compressed gas.

In order to improve the installation of pneumatic directional control valve interchangeability, provides the mounting surface of the main gas inlet port and control identification, valve work State, dimensions and tolerances on the mounting surface requirements.

Five-way pneumatic directional control valve Specifications 18mm and 26mm Part 1. Mounting interface surfaces without electrical connector

1 Scope

This section GB/T 26142 specifies the size of 18mm and 26mm, the maximum rated operating pressure of 1.6MPa without electrical Five-pneumatic control valve mounting direction of the joint surface of the following requirements.

--- Mounting surface dimensions and geometric tolerances;

--- The main gas inlet port and the control identification;

--- Control means controls the results identified.

This section does not apply to the functional characteristics of the mounting surface.

Note. For standard 18mm and 26mm pneumatic five-way direction with optional electrical connector mounting surface of the control valve of the requirements specified in GB/T 26142.2 in.
