1 Scope

This document specifies requirements for the connection of part-turn actuators to industrial valves:

include:

--- Partial rotation connected with industrial valves [see Figure 1a) and Figure 1c)] or intermediate connection support [see Figure 1b) and Figure 1d)]

The flange size necessary for the drive unit;

--- Structural form and size of the driving part of the part-turn driving device necessary to connect with the driven part;

---The size of the flange connecting surface directly connected with the industrial valve and the torque reference value of the connecting flange:

This document applies to the connection dimensions of part-turn valve actuators to valves:

This document does not apply to the connection dimensions of intermediate supports and valves:

Note 1: "Valve" in this document includes "valve with intermediate support" [see Figure 1b)]:

Note 2: When the part-turn drive consists of a multi-turn drive and an integral part-turn gearbox, it is in accordance with the provisions of this document, see Figure 1a) and

Figure 1b): When the part-turn drive consists of a multi-turn drive with a separate part-turn gearbox, connected to the gearbox

The multi-turn drive device is in accordance with the provisions of GB/T 12222, see Figure 1c) and Figure 1d):

a) Direct connection b) Connection with support in the middle c) Combined direct connection d) Combined connection with support in the middle

Description of index number:

1---Part-turn driving device; 5---Gear box;

2---connection surface (see this document for partial rotation); 6---connection surface (see GB/T 12222 for multi-turn);

3---valve; 7---multi-turn drive device:

4--- There is a support connection in the middle;
