The difference between the plunger pneumatic valve and plug pneumatic valve

cock of the pneumatic valve opening and closing is a hole in the cylinder, perpendicular to the axis of rotation of the channel, so as to achieve the aim of opening and closing the channel. Cock pneumatic valve is mainly be used for opening and closing medium pipeline and equipment.
cock pneumatic valve main advantages as follows:
is suitable for the operation, often open/close quickly, light.
fluid resistance is small.
structure is simple, relatively small size, light weight, easy to maintenance. Good seal performance

not limited by the installation direction, the flow of medium can be arbitrary.
no vibration, low noise. Cock pneumatic valve can be divided into the form of the structure pattern, sealing, packing and filling. Points, the form of the channel can be divided into straight-through, three general formula, and the four general formula 3 kinds.
piston pneumatic valve by the pneumatic valve, pneumatic valve cover, stem, plunger, the hole planes, sealing ring, hand wheel, etc. When the hand wheel rotation, through the pneumatic valve rod drives the plunger in the middle of the hole rack up and down reciprocating movement to complete the pneumatic valves open and close function. Between plunger and seal ring used in pneumatic valve interference fit, by adjusting the gland flange bolts, make the seal ring compression produced by the body in the hole surface and side force and pneumatic column circle seal, beyond the Great Wall so as to ensure the sealing of the pneumatic valve, put an end to the internal and external leakage, pneumatic valve small open torque, at the same time can realize the pneumatic valves open and close quickly. Pneumatic valve plunger surface processed by high-precision cylindrical grinder. Sealing ring with strong elasticity, high wear resistance of nontoxic new sealing material, so the sealing is reliable, durable. To improve the service life of the piston pneumatic valve.
in short, the flange plunger pneumatic valve pneumatic valve core is moving up and down. Sealed by pneumatic valve core and pneumatic seat interface, basic is the face seal. Cock pneumatic valve pneumatic valve core is spinning. Seal is sealed. Sealed performance is good. Pneumatic valve operating torque. 。
