JDF1100 Series 3-Way seat valve consists of a pneumatically operated actuator and a 3-way valve body . The actuator is available in three different materials , Pa , Aluminum or stainless steel , Depending on the ambient temperature and customer requirements . Materials available for the valve body are stainless steel 304 316 and 316L . Interchanging of pressure and service ports enables different fluidic circuit functions , such as mixing or distributing mediums t. The flow – optimized valve body of JDF1100 allows excellent flow rates . The tried and tested self – adjusting gland secures a high level of tightness and thus ensures reliable operation over years . The 3 – Way valve JDF1100 is controlled by o pilot valve . It can be equipped easily with an electrical position indicator . For the user . The compact JDF1100 is often an economical alternative to two single shut – off valves

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?
| Focus Point | High Temperature Environment Countermeasures | Extreme Cold Environment Countermeasures |
| Seals | Fluororubber, PTFE | Low-temperature nitrile, silicone rubber, polyurethane |
| Lubrication | High-temperature synthetic grease (low volatility) | Low-temperature grease (low pour point, low viscosity) |
| Air Supply Treatment | Strengthen cooling, efficient water removal | Ultra-low dew point drying (refrigeration + adsorption type), heat tracing |
| Metal Components | Reserve expansion clearance | Select materials with low-temperature toughness, prevent leakage due to cold shrinkage |
| Control Components | High heat-resistant grade coils, heat dissipation, low power consumption | Install insulation boxes, local heating, prevent cold condensation |
| Installation | Keep away from heat sources, add heat insulation plates | Avoid exposure to wind and snow, wrap with thermal insulation materials |
