Product description

2SQ8 series partial rotary electric actuator

1. Introduction

1.1. Purpose

2SQ8 series partial rotary electric actuator is composed of 3sa8 and secondary reducer, which can output a certain angle (usually 90 °) of rotary motion, suitable for ball valve and butterfly valve.

51	64000~90000	—

1.2.3. Output connection form (code position 8).

0: with bracket (special for 2sj);

1: Without support, according to GB 12223-2005 "connection of partial rotary valve driving device (recommended, special for 2SQ)", see figure 58-1 and table 58-3;

2: Without bracket, according to the enterprise standard (special connection, special for 2SQ), see figure 58-2 and table 58-4, figure 58-3 and table 58-6;

9: Non standard special connection, optional code - Y40 can be added after 16 bit code

1.2.4. The total travel time (code position 9) is shown in table 62-2

D	42	21~168	21~168, 15~120
E	21	10.5~84	_______
F	10.5	5.3~42	_______

1.2.5. Power supply (code position 10).

A: 380VAC、50Hz

B: 220 VAC, 50 Hz (only applicable to torque in table 62-3);

Table 62-3 torque range of output shaft N · m

Series	Output torque range
S series（switch type）	180~500	500~100	1000~2000
R series（adjusting type）	110~220	300~600	700~1400

Z: Others.

1.2.6. Reducer type (code position 12).

0: Worm gear reducer;

1: Planetary reducer.

Code positions 5, 11, 13, 14, 15 and 16 refer to the corresponding code positions of 2SA8.

1.3. Structural features

2SQ8 is composed of 2SA8 and secondary reducer, and the multi rotation movement output by SA8 is reduced by secondary reducer to form partial rotation movement.
