 |
Introduction |
I. Actuator Body |
The actuator body made of extruded aluminum alloy,manufacture by precision machining center, |
its internal and external surfaces are hard anodized for low friction and longer service life. |
 |
II. The End Cap |
The end cap made from high-pressure casting aluminum,surfaced with anti-corrosion thermoplastic coatings |
all-in-one compact structure,all single-acting and double acting actuators have similar actuator body and |
cap,changes its acting mode by loading or disassembling spring. |
III. Drive Shaft |
The drive shaft material is medium carbon steel with fine processing and nickle plating so that the pistons have better quality in anti-corrosion, anti-friction, etc. |
 |
IV. Piston |
Piston material is die-casting aluminum alloy. Maximum torque can be output when the actuator is actuated with certain pressure. |
 |
V. Piston Seal |
NBR-70 rubber sealing is applied to ensure the normal and reliable performance of actuator under normal temperature. FPM can be also applied according to clients' requirements. |
 |
VI. Travel Adjustment |
Plus/Minus 5 degree travel can be adjusted through the two bolts. |

Calcium ammonium nitrate is a new high-efficiency compound fertilizer containing nitrogen and available calcium. It has the characteristics of rapid nitrogen supplementation and can be directly absorbed by plants. This product is a neutral fertilizer and has an improved effect on acidic soil. When applied to the soil, it won`t cause soil compaction, in contrast it can loosen the soil, increase the plant's resistance to diseases and promote the activity of beneficial microorganisms in the soil. When planting cash crops, flowers, fruits, vegetables and other crops, the fertilizer can prolong the flowering period, promote the normal growth of roots, stems and leaves, brighten the color, and increase the sugar content of the fruits.

Calcium ammonium nitrate is a commonly used ammonium nitrate replacement product at home and abroad which is much safer for storage and transportation compared with ammonium nitrate in case of fire and explosion.
Not recommend to use with Phosphate Fertilizer or compound fertilizer.
Pay attention to moisture-proof during storage.
