Company Profile

Chengdu MKSVC Flow Controls MFG.Co., Ltd (hereinafter referred to as MKSVC Company) specializes in the research and development, design and manufacture of pipeline valve actuators represented by gas-liquid linkage actuators and related technical services. The company is located in Chengdu Shuangliu Southwest Airport Economic Development Zone, with a production plant area of ​​nearly 3,000 square meters. As early as 2007, we started to develop and manufacture pneumatic-hydraulic linkage actuators. In 2012, we invented the DG series parallel/double-guided fork type pneumatic-hydraulic linkage actuators. The main transmission structure adopts double-guided stability enhancement design, which is an upgraded product of ordinary fork-type actuators.

       In May 2019, China Machinery Industry Federation and China General Machinery Industry Association jointly organized experts to go to Chengdu Chenggao Valve Company, in accordance with the "Technical Conditions for Gas-liquid Actuators for 56″ Class900 Valves" and " 56″Class900 Valve Fitted with Gas-liquid Actuator Factory Test Outline”, and witnessed the joint commissioning of the 600kN·m gas-liquid actuator developed by 


Chengdu Michaelson Company and the 56″Class900 ball valve group of Chenggao Valve. The appraisal committee believes that , The 600kN·m gas-liquid actuator developed has independent intellectual property rights, filling the domestic gap. The appraisal committee unanimously agreed to pass the appraisal.

       The fork transmission box innovatively developed by DG series adopts the parallel and double guide design of the international invention patent. This innovative design fixes the motion trajectory of the transmission slider, eliminates the motion deformation of the piston shaft, minimizes the generation of heat and vibration, and avoids transmission loss and lateral force. Theoretically, 100% lossless transmission of the thrust of the hydraulic cylinder (air cylinder or spring cylinder) can be achieved. Transmission efficiency and motion stability are greatly improved.

The DG series parallel double-guided fork-type gas-liquid linkage actuator has obtained nearly 50 patents. Among them, there are 5 national invention patents and 1 PCT international patent technology in the United States and the European Union. The company is an advanced technology enterprise in 2013, a key new product project unit in 2014, and a national high-tech enterprise in 2014 and 2017. The "intelligent electronic monitoring gas-liquid linkage actuator" was listed as the 2015 National Ministry of Science and Technology Torch Program R&D and Industry project unit.

The company has obtained ISO9001:2008 quality system certification, ISO14001:2004 environmental management system certification, GB/T28001-2011/OHSAS18001:2007 occupational health and safety management system certification. Passed the EU CE certification: obtained the PED pressure vessel directive, ATEX explosion-proof directive, EMC electromagnetic compatibility directive.

According to the IEC61508 safety level certification standard, it has passed the overall SIL certification of gas-liquid linkage actuators, electro-hydraulic actuators, and high and low pressure pneumatic actuators.

Michaelson's DG series double-guided fork actuators include 4 types, 6 grades, a total of 24 specifications and more than 200 varieties. The output torque is 20Nm∽600KNm, and the air source pressure is 0.5MPa∽16MPa. The products provided by Michaelson have been widely used in Sinopec, PetroChina, Southwest Pipeline, West Pipeline, Southwest Oil and Gas Field, West-East Gas Transmission, Sichuan-East Gas Transmission, Kunlun Gas, Huayou Natural Gas, ENN Gas, Ganghua Gas, China Resources Gas and many local pipeline companies are involved in oil, natural gas projects and long-distance pipeline projects. At present, the supporting products cover a full range of valves.

1) Specifications and dimensions of complete sets of valves: 1~32" Class600; 40" Class600; 48" Class600;

2) High-grade, large-diameter fully welded valve: 56" Class900;

3) High-pound, high-torque valve: 1~16" Class1500;

4) High-pound, high-torque valve: 1~12" Class2500;

5) Action time: the actuator outputs 120,000 Nm for 1~2s;

6) Working air source pressure range: 0.4~0.6MPa, maximum 16MPa

We move forward, we create, and we take responsibility.

Michaelson is online, allowing our actuators to operate safely on each of our customers' pipelines.
