 Overview of pneumatic knife gate valve PZ673W-16P-DN200 

 PZ673W-16P-DN200 pneumatic knife gate valve is a valve R & D and production of a strong Germany with the help of compressed air-driven valve. Pneumatic knife gate valve with pneumatic actuator control valves, in order to achieve the valve on and off. Can be divided into upper and lower parts, upper part of the pneumatic actuator, the lower half of the valve. 

 Pneumatic knife gate valve use PZ673W-16P-DN200 Note models: 

 Pneumatic knife gate valve PZ673W-16P-DN200 opening and closing parts of the gate in the direction of movement of the gate and is perpendicular to the direction of flow, manual knife gate valve can only be fully open and fully closed, can not be adjusted and throttle . Gate two sealing surface, the most common mode of gate valve sealing surface formed two wedge-shaped wedge angle with the valve parameters, usually 50, the wedge type knife gate valve can be made into a whole , called the rigid gate; can also be made to produce small deformation of the gate, in order to improve their craft, to make up for the sealing surface angle deviation in the process, this gate is called the flexible gate type knife gate valve is closed the sealing surface can only rely on media pressure to seal, to rely on media pressure on the sealing surface of the ram pressure to the other side of the seat to ensure the sealing surface of the seal, which is self-sealing most of the knife gate valve is the adoption of compulsory sealed, the valve is closed, we must rely on external force to ram pressure to the valve seat to ensure that the sealing surface of the seal. 

 PZ673W-16P-DN200 pneumatic knife gate valve drive device can be electric, pneumatic, manual, bevel gear rotating and other devices. Pneumatic devices can be installed on the air filters, solenoid valves, sensors, such as the installation of drives, pneumatic devices should be specified in the contract. High quality alloy steel welding with small size, light weight, wear resistance, long life, small resistance flow of cross-section, flexible opening and closing the valve is widely used to mine the coal preparation of the plant, slag, and urban sewage treatment, food, slurry in the paper, pharmaceutical, petroleum, chemical, oil, water, steam pipeline, connect or disconnect the line, gold powder, ores, slag, slime, pulp, wood pulp, tailings, fiber, dust, chemicals, sewage treatment, the media, sedimentation tanks, asphalt, silos, export, fruits, grains, slaughter house wastewater flow to open and close, the automatic adjustment or remote control. 


 PZ673W-16P-DN200 pneumatic knife gate valve is mainly the implementation of standards
