Electric actuators are divided into single function and dual efficacy of two kind of way. Once the single function type depends on the advantage, switching power supply common failures occurred. It is on the basis of 38 tube fitting the needs of the automatic control system for automatic is on or off site. Widely used in chemical plant, refrigeration, papermaking industry and other manufacturing industries. It can not only control gas, liquid and steam material, also can control the characteristics of sewage and chemical fiber Product features:
(1) small liquid blocking, pneumatic ball valve is one of all liquid blocking the small gate valves. Even reduce the pneumatic ball valve diameter, liquid friction resistance is very small.
(2) thrust ball bearing can reduce the seat of the friction torque. Make the seat long-term operation stability spirit.
(3) the high pressure gate valve sealing performance is good. Ptfe made of ductile materials such as sealing ring is easy to seal. Ball valve sealing ability to work with medium pressure increase with the increase of.
(4) seat tightness. Because the pneumatic ball valve seat around, do not do exercise. Pneumatic ball valve seat filler sealing is not easy to destroy. Seal the ability to work with physical work increase with the increase of pressure.
(5) for PTFE material has excellent self-lubricating bearing performance, the friction loss of the ball. Ball valves service life is long.
Pneumatic regulating ball valve features:
1. Ball valve by V of the valve and actuator and other accessories. Advanced control valve is a quarter-turn structure.
2. Have excellent control characteristics: v-type valve has a inherent flow characteristics and that's at nearly the same percentage as high as 300:1 adjustable ratio. So V valves can be supplied in wide range of change of precise control. 3. Z large flow volume: because of its streamlined shape and full quarter-turn control, to make the volume of the Z value is extremely high, general ability particularly big, small flow resistance, so you can use the more economical and practical valve size smaller.
4. V valve adopts double bearing structure, high mechanical stability, small starting torque, to ensure the valve has excellent sensitivity and speed of induction.
5. Z big reliable (safe) sex: the body as a whole structure, strong and durable, operation is not affected by the pipeline pressure, and can avoid the leakage of the valve body.
6. Superior metal seat sealing: v-type valve adopts metal valve seat, have buffet compensation function, and are excellent sealing performance and long service life. On the flow, the leakage of 10 or less - 6 x rated flow coefficient.
7. Strong shear capacity: v-type valve adopts metal hard seal structure, V and metal seated valve core in the process of turning, v-notch and valve seat can produce a strong shear to cut off the fiber, and other impurities and 38 tube fitting self-cleaning function, avoid valve stuck phenomenon.
8. Pneumatic V type ball valve structure is compact, small light, convenient installation, easy maintenance.
9. Pneumatic actuators using piston cylinder and crank arm structure, output torque, small volume. Actuator adopt fully sealed waterproof design protection grade is high. Cylinder block USES the import mirror cylinder, oil free, small friction coefficient, corrosion resistance, with super durability and reliability. All drive bearing adopts boundary self-lubricating bearing without oil lubrication, ensure that the shaft does not wear.
