How to install a straight stroke pneumatic actuator?

The installation of linear pneumatic actuators requires strict steps and precautions to ensure their efficient and stable operation. The following is a detailed installation guide: 1、 Preparation before installation Check cylinder model and status: Confirm that the cylinder model matches the valve, and check if the cylinder is in the closed state (large-diameter valves can also be installed in the open state). Check the direction of cylinder rotation: counterclockwise rotation usually opens the valve, clockwise rotation closes the valve, and it should be consistent with the direction of the valve. Check the center distance of the connecting holes: Ensure that the center distance of the cylinder connecting holes is consistent with the center distance of the flange connecting holes on the valve, and the shaft dimensions need to match. If they are not consistent, a square sleeve can be added. Clean air source interface: The air source interface connected to the actuator must be very clean to avoid impurities entering

Introduction to the stroke and control mode of electric actuators

1、 Type of itinerary and applicable scenarios Electric actuators can be divided into linear, angular, and multi turn types based on their motion form. Their stroke characteristics and applicable scenarios are as follows: 1. Straight stroke (Type B) Travel range: Linear displacement, usually a push-pull structure, with travel length customized according to valve type (such as gate valve travel up to tens of centimeters). Applicable scenarios: In situations where linear position control is required, such as flow regulation of regulating valves and globe valves. Typical applications: Flow control valves in chemical production, material conveying in welding lines in the automotive industry.

The working principle of the regulating valve

The regulating valve is a key equipment used to accurately control the flow of fluids (gas, liquids or steam) in the industrial process. Its working principle is to adjust the flow rate by changing the circulation cross-section between the valve core and the valve seat. The following is a step-by-step explanation of its core working principle: 1. Basic structure The regulating valve usually consists of two parts: the actuator and the valve body: Actuator: Receive control signals (such as electric 4-20mA, pneumatic 0.2-1.0bar) and drive the valve stem movement. Valve body: including the valve core, valve seat and flow channel, and the position of the valve core determines the flow rate and flow rate.
