Features
VC9000 series products represent one of the current domestic and international level of control valves, its technology from Europe, WICKAR company through the introduction, digestion and absorption to China, joint production of products in line with China's national conditions, in order to improve the technical level of China's control valves, narrowing the gap with Europe and the United States and other countries, saving foreign exchange has a major contribution and historic, breakthrough significance.
The valve body streamlined design, unique appearance design of the implementation of the installation form, very chic and novel, while the machine makes full use of aesthetic principles, giving the control valve a strong sense of beauty;
◆ Valve internal modular design, a variety of structures in the same body can be interchangeable, versatility;
◆ Automatic centering snap-in valve seat, automatic centering, good guidance and easy disassembly;
The use of line seal structure, can be closely cut off, up to 0 leakage, to overcome the traditional straight stroke can not cut off the defects;
The valve core, valve seat do not need to be ground, can achieve tight cut;
The valve body is designed with the principle of fluid mechanics, with small flow resistance, large circulation and small pressure drop loss;
The same specification has a variety of Cv value, just replace the valve seat can be very easy to achieve;
◆ If the spring-free piston actuator is adopted, the on-site replacement of gas opening and closing is very convenient and quick, which can be realized in tens of seconds;
◆ On-site maintenance is simple, fast and economical. The valve body does not need to be removed from the pipeline and does not need special tools. Unscrew the nut and remove the valve cover. The valve core and valve seat can be conveniently taken out for inspection and maintenance in turn. On-site installation can also be easily installed back;
The use of valve core, valve stem integration, to overcome the traditional valve core stem with threaded connection is easy to fall off and bear the pressure of small defects;
◆The whole machine has compact structure, small volume and light weight;
◆ This product can have standard type, regulation cut-off type, bellows seal type, reduce cavitation type, noise reduction type and other variants;
◆ There are three driving modes: pneumatic straight stroke piston type, pneumatic film type and electric type.

◆ Surface coating color: VC9000 appearance combined with aesthetic principles and special surface treatment, the appearance is very delicate and beautiful. The valve body shall be uniform dark gray, the bracket connector stainless steel natural color or dark gray, the actuator yellow, the reaction handwheel seat gray, the positive action handwheel seat black, and the handwheel blue. The distinction between positive and negative effects reflects the consideration of humanization, which is convenient for instrument workers to distinguish easily on site.
◆ Identification of components: The main components of VC9000 such as valve body, valve core, valve seat, etc. are marked with materials, numbers and identification numbers. One is to facilitate factory management, and the other is to fully stand in the customer's point of view to order spare parts.
◆ Special requirements: material inspection, liquid penetrant inspection (PT), radioactivity inspection (RT), flow characteristic inspection, low temperature test, steam inspection, complete oil ban and water removal treatment.
