2SB8 series straight stroke electric actuator

key word:Heat exchange element


Product description

2SB8 series straight stroke electric actuator

 

1. Introduction

1.1. Purpose

2SB8 series straight stroke electric actuator is composed of 2SA8 and straight stroke components. It can output linear motion and is suitable for gate valve and globe valve.

1.2.1. Output connection form (code position 8).

A: No bracket, according to GB12222;

B: No bracket, other non-standard special connection forms;

C: There's a bracket.

1.2.2. Output speed (code position 9), see speed codes D, e and F in table 62-4 and table 62-5

1.2.3 output stroke (code position 12), see stroke codes 0, 1, 2 and 3 in table 62-4 and table 62-5

code positions 5, 10, 11, 13, 14, 15 and 16 refer to the corresponding code positions of 2SA8.

1.3. Structural features

2SB8 is composed of 2SA8 and straight stroke part. The straight stroke part converts the multi rotation motion of 2SA8 output into up and down linear motion.
