Selection of pneumatic actuator cylinder solenoid valve

Users generally have a better understanding of  pneumatic actuators, and they do not know much about the accessories of Pneumatic Actuators, but in fact, the role and importance of accessories as Pneumatic Actuators are not lower than that of pneumatic actuators themselves. Let's take a detailed analysis of one of the accessories of pneumatic actuators - solenoid valves. 

1. the introduction of Pneumatic Actuator solenoid valve
Solenoid valves are used for electronically controlled operation of pneumatic valves "on" or "off". Compliant with NAMUR connection standards, it is mounted directly on the side of the pneumatic actuator without the need for a pipe connection. According to the needs of the instrument control system, single electronic control or double electric control can be selected. The two-position five-way solenoid valve is equipped with a double-acting actuator, and the two-position three-way solenoid valve is equipped with a single-acting actuator. At the same time, the product has basic type (IP67) and explosion-proof type, and the explosion-proof level is Ex dIIBT4, which is explosion-proof and suitable for explosive environment places in the factory. It is also possible to select the appropriate voltage according to the needs.

2. Technical parameters of pneumatic actuator solenoid valve.
Structural form: sliding
Mode of action: electromagnet or manual operation.

Manual status locking can be achieved by pressing and rotating the manual action knob.
Return mode: pneumatic spring return, mechanical spring return, electromagnet operation return.

How is the solenoid valve connected to the pneumatic actuator?
There are two connection methods, one is the pipe connection and the other is the Namur connection, the pipe connection is connected to the cylinder with a stainless steel pipe, and the Namur connection is to paste the solenoid valve directly to the imported pneumatic actuator, but this requires the cylinder to meet the Namur standard. Generally speaking, quarter-turn imported  pneumatic actuators  can be connected with Namur or tubular connections, while linear cylinders can only be connected with tubular connections.
