Product description

DQW series partial rotary valve electric device

1. Introduction

1.1. Purpose

DQW series partial rotary valve electric device is composed of DZW valve electric device and secondary reducer. It can output a certain angle (usually 90 °) of rotary motion. It is suitable for ball valve and butterfly valve

1.2. Model meaning

Code position 1 2 3 4 5 6

DQW ** - ##@@$$&& – !! + Z additional special selection code

DQW --- DQW series electric device code of partial rotary valve

**-----------Torque grading

##--------------90 ° full stroke time

@@-----------------Output connection form

$$------------------Direction of rotation

&&-----------------------Motor

!!-------------------Switch configuration

1.2.1. Torque classification (code position 1) and 90 full travel time (code position 2) are shown in table 66-1

Table 66-1 torque grading and 90 full stroke time of DQW series partial rotary valve electric device

Code position 1	Nominal torque	Max. torque	Code position 2

6000	60 000	72000	47
8000	80 000	96 000	50

1.2.2. Output connection form (code position 3)

1: It is selected according to GB 12223-2005 "connection of driving device of partial return drilling valve" (see figure 58-1 and table 58-3);

2: According to the enterprise standard (see figure 58-2 and figure 58-1, figure 58-3 and table 58-5);

9: Non standard special connection, optional code - ZY40 can be added after standard code

Note: code positions 4, 5, 6 and additional special selection refer to the corresponding code positions of DZW

1.3. Structural features

DQW is composed of DZW and secondary reducer. The multi rotation motion output by DZW is decelerated by secondary reducer, and then the rotation motion with fixed angle is output.
