Product Overview 
 Z641 Series pneumatic valve with manual wedge is a pneumatic actuator (double-cylinder, with a buffer body), and manual and its protection agency (manual and pneumatic self-locking - manual conversion devices), low gate frame the next shot the valve. As a result of the double-valve cylinder structure, with single-cylinder pneumatic valve than double the lift force increases. This is a fundamental solution to the single-cylinder pneumatic wedge gate valve body dead and some open defects. And, since the valve body with the buffer can effectively close the valve gear lighter, due to the piston down the impact caused by the valve sealing surface and dray valve sealing surface of the wear and tear, but also to avoid the death gate card the phenomenon. 
 In order to meet the user to achieve automation, the company in addition to supply the products, they can also be provided separately, including stents, including the cylinder block, to help users of the existing wide range of manual valve transform, the pneumatic cylinder actuators part of the manual valve of the valve installed in a large cover, can constitute a pneumatic cylinder - manual dual gate. 
 Because of its advanced technology, reliable performance, easy operation and maintenance of switching, has been oil, chemical industry, metallurgy, electric power, shipping and other departments as the transmission of gas and liquid media channels opening and closing device and widely used.
