Overview
Z641F Pneumatic Gate Valve
Product Details
Z641F Pneumatic Gate Valve
Z
Z6S41The series of pneumatic wedge gate valves with manual function are equipped with pneumatic actuators (double-layer cylinders with buffering mechanism) and manual and its protective mechanisms (manual and self-locking pneumatic)-Low bracket rising stem gate valve with manual conversion device. Due to its double-layer cylinder structure, this valve has doubled the lifting force compared to single cylinder pneumatic gate valves. This fundamentally solves the problem of some valve bodies of single cylinder pneumatic gate valves being wedged and unable to open. Moreover, due to the buffering mechanism of the valve, it can effectively reduce the wear and tear on the sealing surface of the valve plate and valve body caused by the downward impact of the piston when closing the valve. At the same time, it can also avoid the phenomenon of the gate plate getting stuck.
In order to cooperate with users to achieve operational automation, in addition to supplying this series of products, our company can also provide separate cylinder blocks including brackets to help users modify a wide variety of existing manual gate valves. By installing the dual cylinder pneumatic actuator part on the valve body cover of the manual gate valve, a dual cylinder pneumatic system can be formed-Manual dual-purpose gate valve.
Because of its advanced technology, reliable performance, convenient operation, switching and maintenance, it has been widely used as a pipeline switching device for transporting gas and liquid media by petroleum, chemical, metallurgical, electric power, maritime and other departments.
