Pneumatic Ball classification and their characteristics.

Pneumatic valve O-Ball and V-ball points. O type ball floating structure, core for precision castings, looks hard chrome plated, seat with PTFE material, the same stream crossings and pipe diameter, maximum flow capacity, flow resistance is extremely small, closed without leaks, generally make the switch valve, especially for high viscosity, V-ball fixed structure, has opened a V-notch ball core, can be achieved with fiber cut, granular media. 

Depending on the choice of process equipment pneumatic or electric actuators, pneumatic valve and were composed of electric valve, pneumatic valve which such adjustment is required to achieve proportional valve with positioner, electric valve adjustment as required to achieve proportional election electronic or electric actuator with servo amplifier. 

From the material, can be divided into: carbon steel ball valves, stainless steel ball valves 304, 316 and copper ball valve; press pressure can be divided into: low-pressure valve and ball valve high pressure pneumatic valve: mainly used in oil, gas, hydraulic oil, mechanical engineering low-pressure pneumatic valve industry: mainly used in water and other corrosive media pipeline! Knife gate valve products and their use in the Notice Type: Knife gate valve for opening and closing parts, fluid motion direction and the direction perpendicular to the gate, manual knife gate valve can only be fully open and fully closed, can not be adjusted and throttling. Ram has two sealing surfaces, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, wedge type knife gate valve can be made of a whole, called rigid gate; while also be made to produce small deformation gate to improve its process, to make the sealing surface angle deviation generated in the process, which is called the flexible gate knife gate valve is closed, the sealing surface You can only rely on media pressure to seal, that the medium pressure to ram pressure to the sealing surface of the valve seat on the other side to ensure the sealing surface, which is self-sealing. Most knife gate valve is sealed by force, that is when the valve is closed, to rely on external pressure to force the gate valve to ensure sealing of the sealing surface of the valve class should generally be installed horizontally in the pipeline.
