We strive to create Pneumatic Stainless Steel Butterfly Valve, Pneumaic Actuator With Manual Override, Motorized Ball Valve Actuator with reliable performance and customer satisfaction to serve users at home and abroad. We take 'people-oriented, professional manufacturing' as our work philosophy, and pay more attention to the outstanding advantages of products in terms of safety, reliability and energy saving. To survive with quality is our slogan but also our action, customer demand is our pursuit, which has been the direction of our enterprise.

Autorun pneumatic actuator has two kinds of models: 0°-45°-90° and 0°-90°-180°. The air intake "2" after the intake ends of the piston movement was designed to both ends there are auxiliary pistons produce mechanical constraints to achieve a middle positon, can be used directly out of both ends of the adjusting screw is easy to adjust the middle point of view, such as 20°, 30°, 50°, 75°, and 95°, 120°, 130°, 150°, 175° and so on.

Three position pneumatic actuator operation requires the design of a solenoid valve control loop system to complete the operation, the control principle as follows:

Position 1 (middle)

Air pressure at the same time and D into the two port, air from the exhaust port 4 and C, 2 as an internal piston, D mouth is by putting restrictions on secondary piston within the piston located in the middle of the booking.

Position 2 (open position)

Air pressure at the same time into 2 and the C port, air from the discharge port 4, and D, two of the internal piston to move, C auxiliary port for the lifting of restrictions on putting the piston position to reach the fully open position within the piston smoothly.

Position 3 (fully closed position)

Air pressure into 4, the air discharged from the 2, the internal piston moves to the middle reach the fully closed position. Provides 0°-45°-90° spring return position type specification, when somebody stops breathing power (or gas source failure), an internal piston back by spring force to the fully closed position.

Based on the principles of high starting point, high positioning and high standards, we are equipped with a professional technical team that has been engaged in research and development in the industry of manufacturing Sliding Table Electric Cylinder with Anodized Aluminum Cylinder Body for many years. Innovation is the source and power of circular economy development. Our company always puts innovation in the top position of the company's development. We adhere to the enterprise culture of "loyalty, diligence, and enterprise".
