The rare-earth metal thick film heating technology is one of
today's most innovation and forward-looking solution for electric heating field.The
thick film heating tubes/elements are produced by screen-printing dielectrics
(5 layers), resistance (palladium-silver), conductor (silver) and isolation
glazes on the substrate and sintered 7-9 times at temperature over 900℃.
With 3000W Thick Film Heating Tube simple tubular structure,
it can heat water flow inside the tube. Electric Circuit printed on tube
surface, to heat the water flow inside. For applications where space is limited, this simple profile
heater offers high thermal power density and fast response times to heat up or
cool down (due to low thermal mass)
JIEDA company can supply products according to customers'
drawings and offer our clients reasonable prices. Our company also can develop
heating solutions and products together with customers.
Those new types Thick Film
Heater Tubes are special designed for Through-Flow applications, such as
Instant Hot Water dispensers, instant water heaters, instant coffee maker,
electric heating water faucet, water purifier instant water flow heater under
sink, industrial water flow heater. Maximum heating power: up to 6kw on single
tube.

Installation, Use & Maintenance:
1. Before Installation, it's necessary to clean the valve and remove possible defects caused in the transportation process.
2.Check carefully whether marks and the nameplate on the valve meet operating requirements.
3. This valve can be insstalled on pipelines at any angle.
4. This valve shall be fully open or fully closed in running and not be used as a throttle valve, or else its sealing surfaces will be washed and get worn faster.
5. For Long term storage, it shall be stored in a dry and ventilated room whth periodic check to avoid rust.
6. Knocking shall be avoided in the transportation process.
Structural Features:
1. Use a Cylinder as the actuator to drive the gate directly to move up and down, with fast opening/closing.
2. The double gates adopt floating connection to produce reliable one-way seal under the medium pressure action. Also the floating connection can drive the gate to rotate up in opening/closing due to misaliginment of axial lines so that the friction grains between the valves' gate and seat are distributed evenly to produce no linear abrasion, thus improving its service life greatly.
3. Sealing surfaces of the valve's body and gate are lined with anti-wear ceramics, with excellent resistance to abrasion.
4. Being compact, it's easy for transportation, installation and maintenance.
Working Principle
When the cylinder drives the gate to move downwards through the valve's stem, sealing surfaces of the valve's gate and body will be engaged to cut off the channel, namely, closing; the other way around is opening.
