4EPLSV330/35Â Proportional directional valves,The port of this product has the same size with Bucher LV22.It can be replaced and has functions superior to LV22. It can realize compound control actions.It's applied to the loading circuit of engineering machinery to conduct proportional control on actuating mechanisms such as oil cylinder and winch motor.
This valve have been used on XCMG truck crane model:QY70K more than 3 years,and quality feedback is very stable.
Application:
Widely used in all kinds of construction machinery, agricultural machinery, road and bridge machinery, sanitation machinery, mining machinery, excavators, draglines, having advantages of beautiful and delicate, high pressure and flow, easy installation.
Functions and features:
1. An international advanced LUDV system is adopted to realize proportional flow distribution to all actuating mechanisms. Besides, flow is not influenced by load.
2. This valve is suitable for a variable capacity pump. It adopts many buffering measures to make system pressure more stable.
3. The dual connection structure valve body improves the rigidity of valve body, enables the product not to easily deform under high pressure and avoids valve sticking.
4. The circular arc groove orifice of valve rod can make flow more accurate and action more stable so as to cater for different working conditions.
5. The port of this product has the same size with Bucher LV22. It can be replaced and has functions superior to LV22. It can realize compound control actions.
Characteristics
1. Adopting the fashionable LUDV control technology of the world, it can provide the max displacement according to The oil pump to realize proportional flow distribution of different execution mechanisms;
2. The flow distribution is not relative to the load pressure;
3. Valve lever uses circular orifice, having a more precious flow, more stable movement, to meet various of demand in Different working case;
4. Using median position low pressure relief mode is expandable to the variable displacement pump system in which the Variables cannot reach zero displacement, also applicable to constant delivery pump system at the same time.
5. Adopting multi-piece overlay, multi-channel proportional flow valve set can be formed by overlaying of working Couplets, to meet customer's demand, maximum to 8 couplets;
6. Closed core type used in variable pump, built-in load holding valve, built-in tank back pressure valve, having a better
Basic techincal data
1. Max. Working pressure: 35MPa
2. Flow rate range: 30~330L/min
3. Operation mode: Electro-hydraulic or hydraulic control

We supply affordable LED marine lighting to a wide range of clientele,and can fulfil any order, large or small, from small private tanks to large industry sized outfits.Besides,we made aquarium sets use super bright fully submersible LED strip lights which create a beautiful effect on the water and are safe to use all year long.
An aquarium adds a decorative feature to any home. LED lights are becoming widely popular among the aquarium enthusiasts. Specialized LED Aquarium Lights help create a better environment for the fishes and the aquatic plants. They consume less energy and generate less heat as compared to the as compared to the normal lights. The new LED lights do not produce excessive heat even after continuous operation, which helps maintain the water temperature and does not allow for excess evaporation. This helps create a healthy environment for the corals and fishes. LED Aquarium Lights are revolutionary products that add to the beauty of a home while being energy-efficient, environmental-friendly and convenient.
Key Features
1.The lifespan is over 50000 hours,low maintenance costs.
2.Energy conservation,saving over 80% energy than the traditional HPS.
3.High light efficiency,90% of the light will be absorbed by the aquatic plants,while just 8%-10% to the HPS.
4.Build-in cooling system,could solve the heat dissipation excellently.
5.Built-in power supply, CE approved, No setup required, just simpler and safer plugs directly into AC85V-264V, no reflector & ballast needed.
Application
1. coral reef lighting,fish tank lighting,coral reef tank lighting
2. aquarium lighting,aquarium art,aquarium shop,aquarim centre
3. fish bowl lighting,fish lighting,freshwater lighting,saltwater lighting
