180° SPRING RETURN ACTUATOR 4thG WITH 90° FAIL SAFETY POSITION
The 180° Spring return actuator with 90° Fail safety position is used for 0° -90° -180° Operations where in case of air failure the actuator has to return to the 90° Position. At both ends of the actuator a spring set is mounted and the compression on both sides of the springs is caused by the rotation from the 90° Position. The fail-safe operation is achieved by the extension of the compressed springs that bring the actuator from 0° Or
180° Position to 90° Position. The external travel stop is available as a standard in fully open position (180° ) and in fully close position (0° ), and it is easily and precisely adjustable of +/- 4° In both directions.
In order to control the operation of ALL TORQUE 180° With 90° Fail Safety Position a system of solenoid valves controlling a sequence of air supplies to the actuator is required as described besides: The actuator may be controlled by two 3/2 way solenoid valve or by one 5/3 way solenoid valve.
Characteristic:
1. Top mounting connection is according to VDI/VDE3845 standards, permitting direct installation of accessories such as positioner and limit switch box.
2. Bottom mounting connection is according to ISO5211 and DIN3337 standards.
3. Air supply connection is according to VDI/VDE3845 and NAMUR standards to install solenoid valves conveniently.
From the first product in 1999, ALL TORQUE® Developed aggresstively with the highly approval from our customers (overseas mainly), for our focus on the quality, technical innovation and deep understandings of the products.
During this period, ALL TORQUE; Developed the distinctive features from others:
1. Win the patents for the special design;
2. All kinds of stainless steel Valves, high strength, good sealing performance, and small torque resistance;
3. Two Piston, Four Piston. The unique patented structure, great appearance, long service life, suitable for the complex application environment, user-friendly installation;
3. Limit switch box, great appearance, IP67;
4. With the breakthrough in design, ALL TORQUE® Manual gear operator realizes the automatic protection by switching from the pneumatic control to manual, and meet the IP67 protection requirement. We are applying for the patents. The feature is the Integrated manual-pneumatic safe shift. We are the only one that could offer this high-end products in this field through the whole world. As the other similar products in the market, , there is only the switch air valve assemblied in the handwheel box as the accessories. (Find the details in the attachment)
Up till now, ALL TORQUE® Has become one of the biggest manufacturer for the pneumatic actuator, and related products in China, and also gotten the ISO9001, CE, ATEX.
Besides the high precise production faclities, ALL TORQUE® Foucs on the test equipments to guarantee the great quality, such as: Portable Spectrograph, Vickers Hardness Tester, Roughness Tester, Micron-sized Film Thickness Tester; Valves Pressure Tester, Air leak Tester, Actuator Springs Pressure Tester, Actuators Liftetime Tester, Actuator Output Torque Tester, Limit Switch Box Tester
All Torque is distinctive.
Believe ALL TORQUE® , Believe yourself.
As the developing company, ALL TORQUE® Annually turnover is 8 million dollars at the moment, but the actual production capacity could reach 15 million dollars.
Taking the OEM mainly, our 90% products exported to the Euro, American, and Japan markets. Also we gradually expand the domestic market, with the aim to replace the imported brands, and to be the top level in the field of the control process system and pneumatic actuators.
We are developing the high level of Electrical Actuators with explosion-proof.
We are willing to take the challenge to develop the customerised products.
