Description
Pneumatic Globe Control Valve with Jacket
A single-seat control valve with the heated jacket is a kind of top pilot single seat valve, which has a simple structure, well sealing, high flow rate, and stable application performance. A reasonable top spiral system can avoid vibration during a small opening percentage, so as to extend valve working life.

Heat Jacket Features of Pneumatic Globe Control Valve with heated Jacket
1.Temperature range: it is suitable for a variety of temperatures.
2, chemically stable: suitable for a variety of chemical environment corrosion resistance (than aluminum tintype insulation sleeve has obvious advantages)
3.Specification size: can do standard parts and be customized according to the site’s use.
4. insulation thickness: 5mm-70mm, according to the working conditions of the demand set
5.Insulation effect: to achieve the standard requirements of the insulation industry prevailing
6.space to adapt to a wide range, in the room of a small area can also use the insulation cover. (With the traditional insulation than there are apparent advantages)
7.It can be disassembled, repeatedly used, easy to clean, overhaul, etc.
8.the appearance of coordination is beautiful.
Second, the pipe insulation sleeve product performance.
1, insulation sleeve insulation effect is good, high and low-temperature resistance (high-temperature resistance 1000-280 ℃, low-temperature resistance negative 70 ℃)
2, good chemical stability, resistance to various chemical corrosion; insect-resistant, anti-mold.
3, insulation sleeve fire retardant (fire A class – non-combustible, GB8624-2006, German standard DIN4102, A1 class)
4, insulation sleeve aging resistance, weather resistance
5, insulation sleeve waterproof, oil-proof: with good water repellent properties, oil-proof
Third, the pipe insulation sleeve is highly adaptable: (and traditional insulation comparison has obvious advantages)
A: Can be used repeatedly (traditional insulation can only be used once)
B: applicable to different shapes of the pipeline, equipment, especially for “shaped parts” more advantageous, even in
Even in the traditional insulation can not do the case, removable flexible insulation clothing can also do (because the conventional insulation is “rigid material”)
Insulation is “hard material” processing, not easy to bend deformation)
C: space to adapt to a wide range, in a small room of the region can also use the insulation clothing (set)
(traditional insulation of narrow space sometimes may not be able to do)
D: environmental adaptability: to some “corrosive” environment, more advantageous than the traditional insulation.
(Because the traditional insulation appearance is aluminum or iron skin is not corrosion-resistant)
Fourth, the pipe insulation sleeve performance indicators.
1, thermal conductivity: 0.030W / M? K-0.040W / M? K ± 0.005 (at room temperature)
2, high and low-temperature resistance: high-temperature resistance 1000-280 ℃, low-temperature resistance negative 70 ℃
A）Cooling type
B）Low temperature type (use temperature below 300℃)
C）Medium-temperature type (use temperature 300–600℃ or more)
D）High temperature type (use temperature 600℃ or more)
3、Flame retardant performance: non-combustible (fire A grade, GB8624-2006, German standard DIN4102, A1 grade)
4、Density: 110-220Kg/m3
5、Thickness: 10-150MM
6、Humidity absorption rate: <5%
