1: Optimal Sealing by O-Ring
Highly durable Teflon O-Ring was used and special coating
was done at the contacting point of O-Ring to ensure perfect
Sealing and secured operation at fire detecting.
2: Shock proof structure with steel ball support method
With 8 steel ball support structure for shock esistance,
it Is reliably safe from external impact and free from
damage And leakage
3: Low Assembly Load
By minimizing the assembly load with o-Ring Sealing Method,
safety is secured with low pressure inside the Head.
4: Excellent Design
As the head is installed in the building, aesthetic design By
minimizing heat detecting with small head was made.
TECHNICAL DATA
- Tensile Strength : 28 ~ 35 MPa
- Elongation : 200 ~ 400%
- Temperature : up to 500°F (260 C)
- Hardness : R25 (Rockwell)
Application
- Control valves, Rod, piston
FEATURES
- Elimination of costly seal failure or blowouts
- Reduced installation costs
- Reduced equipment downtime with exact seal specifications
- Reduced inventory costs
- Lower friction / Friction a measurement of the resistance to sliding between a seal and hardware surfaces, is directly related to seal material coefficient of friction and the total load.
- Longer Life / Individual sealing rings expand under bolt loading to maintain a tight, virtually leak proof set with up to 50% longer services over braided styles.

Based on these efforts, we have won awards for excellent suppliers to major power generation companies in Korea and expanded our production lines by steadily increasing sales. We are now trying to move beyond the domestic market to the global market.
SPIRAL WOUND GASKETOutstanding capability for high temperature and high pressure
Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditionsEfficient production for any type of dimensions such as round or oval type, etc.Outstanding sealing capability as it is produced according to the pressure of unbalanced flange.
Hoop and Filler materials can be selected according to special operating conditions.
GRAPHITE MOLD PACKING
â?¢ Graphite Tape Packing is the packing that compressed and molded in a certain dimension for easy installation.
â?¢ The graphite's self-lubrication capability and low coefficient of friction allow to use in a wide range without giving damage on the reciprocating and rotary shaft.
â?¢ If you want to disassemble only gland without disassembling pump and valve, you can just cut it and deliver.
â?¢ You can get better sealing effects if you use with ALS910C, ALS900G and ALS955W depending on the use purpose.
RING JOINT GASKET
Ring joint gasket is a type of pressure energized gasket used on pipe flanges, pressure vessels, Valve bonnets handling, high pressure steam, gas, hot oil, solvent vapor at high temperature.
DONGSUHs experienced technology offers many different types so that customers may select the most suitable one in accordance with operating conditions.
