Gas valves - Import export

Individual filled gas springs are excluded from replacement. Gas springs are maintenance-free, self-contained systems that are filled with nitrogen under high pressure. For end-of-travel damping and lubrication, a defined amount of oil is also contained inside. The gas springs contain a nonreturn valve in a threaded pin on the pressurised pipe, which allows the pushing force to be lowered at a later time. Gas pressure springs in the sizes 04/12 and 06/15 must be stored and installed with the piston rod extending downwards. As of size 08/19, storage and installation in any orientation is possible. Keep in mind, however, that end-of-travel damping is effective only when the piston rod extends downwards. As a consequence of the physical properties when filling a gas spring, a tolerance range of ±5 % results for the rated pushing force. Gas springs are filled with nitrogen under high pressure and under no circumstances should they be opened or overloaded.

ALFAMAK is one of Turkey's leading gas spring manufacturers. Established in 2003, our company has been operating in the industry for 19 years and has gained a reputation for success. Gas spring is a new technology which comes instead of standard steel or polyurethane springs. A gas spring has a container of compressed Nitrogen gas with Piston Rod , Bush, Rod Rings, Valve etc. The Gas Springs are used in Cold Stamping industry to form, cut and fix the sheet metal inside the die. Many auxiliary materials are used for different purposes in the gas spring. Rod wiper, rod guide and rod seal are used on the inner surface of the bush. The purpose of the rod wiper is to prevent the oil and chips in the die from entering the gas spring. The rod guide is used to carry the load in case of axial force on the rod during use. The most important auxiliary material for sealing is rod/piston seal. It directly affects the performance of the product by keeping the gas in the gas spring.

The Round Lead Seal is designed with two parallel holes and a knot chamber. During fitting the wire or string is threaded through the two parallel holes and crossed inside the knot chamber before closing with the sealing tool to prevent slippage. The LS31F Seal Cross-hole Lead Seal is designed so that the lashed wire is crimped together when the seal is compressed with the sealing tool. The effect of crimping the lashed wire together alleviates any chance of twisting the wire out of the hole without leaving clear evidence of tampering. To optimize security the sealing tool dies can be engraved to emboss or deboss characters /numbers/logo onto the seal so giving reference to the application user. Recommended applications Gas, Water & Electric meters, Drums, Valves, Refineries, Post Bags, Cages, Lockers. Material 99.9% Pure Lead ** Click for more **
