DC 24 Volt Ball Hydraulic Solenoid Valve Normally Open / Closed 23QDF 24QDF
Introduction
1 . The 23QDF6 and 24QDF6 solenoid ball valves are used in 2 - way cartridge valve assemblies with minerals as working medium , to realize pilot control of leaks . While satisfying the need of pressure drop and flow control , they may also serve to control the directions of other actuators .
2 . The W23QDF6 and W24QDF6 ball type solenoid reversing valves are manufactured using anticorrosive marerial and special workmanship , hence suitable for working with non - mineral oil mediums such as emuilsified liquid , high - water - based hydraulic oil , and ecen suitable for working in pneumatic conreol units .
Model Designation
1 . For use at ambient temperature – 20 ~ + 40 ℃ , relative humidity ≤ 95 % , and with no exposure to weathering or explosive gas .
2 . The magnet is intended for long- term working .
3 . Rated reversing rate of solenoid valve is 120 times / min when power continuity rate is 60 % .
4 . Range of variation in working voltage of magnet is + 60 % ~ -15 % of rated working voltage .
5 . Reliable reversing for 2 × 104 times under given conditions .
1 ) Under the load of rate working pressure ;
2 ) When working under rate working voltage ;
3 ) Under power continuity rate of 60 % and reversing rare of valve is 120 times / min ;
4 ) Under ambient temperature of 40 ℃

Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
