O to cut off the working principle of the pneumatic valve ball

and pneumatic cut pneumatic ball valve products feature
( Fluid resistance small, pneumatic ball valve is for all pneumatic valve in a fluid of least resistance, even reducing pneumatic ball valve, the fluid resistance is small.
( Thrust bearings reduce pneumatic valve stem friction torque, can make the pneumatic valve stem long smooth and flexible operation.
( Pneumatic valve seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure is easy to be sealed, and pneumatic ball valve pneumatic valve sealing ability increases as the medium pressure increases.
( Pneumatic valve rod sealing is reliable, the pneumatic valve stem will only be used as the rotation without lifting movement, pneumatic valve stem packing seal is not easy to damage, and increased as the medium pressure sealing ability.
( Because the materials such as ptfe has good self-lubrication, with ball friction loss is small, so the ball long service life of pneumatic valve.
and pneumatic cut pneumatic ball valve
product use and working principle of pneumatic cut pneumatic ball valve pneumatic actuator with high precision and high quality of pneumatic valve, ball belongs to the pneumatic switch pneumatic ball valve. Pneumatic cut pneumatic ball valve sealing performance is good, large flow capacity, simple structure, long service life and easy maintenance. Pneumatic cutting off the ball of the pneumatic valve actuator has a simple structure, compact, performance is remarkable, the output torque, etc. Pneumatic switch pneumatic ball valve also lead limit switch, solenoid pneumatic valve, pneumatic valve and relief. - 。 MPa gas source can be realized on off the operation, and sent out two indicates a pneumatic valve on the passive contact signal switch. Actuator cent two kinds of models of single and double action. Unique advantage of single acting is that once the power supply fails, the pneumatic switch pneumatic ball valve will automatically according to the requirement of the control system in an open or closed position. Pneumatic cut pneumatic ball valve is widely used in chemical, petroleum, textile, electricity, food, pharmaceutical, refrigeration, aviation, aerospace, paper and other industries, can not only control gas, liquid and steam steamed medium, can also be applied to control the nature of the sewage and contain fiber.
