Shijiazhuang Laiye Import& Export Trading Co., Ltd. is one of the leading manufacturers and suppliers of sd5 manual monoblock directional valve in China, also supports customized service. If you're going to wholesale high quality sd5 manual monoblock directional valve made in China, welcome to get pricelist from our factory.
The SD5 manual monoblock directional valve is a compact, integrated multi-way directional control valve. The valve body is integrally cast using a single-piece casting process, eliminating inter-plate sealing and reducing the risk of external leakage. This design also allows for compact installation dimensions, making it suitable for equipment with limited cabin space. Rated flow rate is 45 L/min, maximum working pressure is 250 bar, and it can be configured with 1 to 7 ports. The operating temperature range is -40°C to +80°C, and it is suitable for oil viscosities of 15-75 mm²/s. Control methods include manual, hydraulic, pneumatic, electric, and electro-hydraulic control, which can be flexibly selected according to system requirements.
This series of products features precise control of the valve core and valve orifice clearance, resulting in low internal leakage, low pressure loss along the valve body, and sensitive operation. The valve body surface is phosphated for excellent corrosion resistance.
The SD5 manual monoblock directional valve is mainly used in small loaders, mini excavators, skid steer loaders, forklifts, tractors, combine harvesters, aerial work platforms, and truck-mounted cranes, and is particularly suitable for small to medium-sized mobile hydraulic systems with limited installation space, clearly defined functions, and no need for future expansion.

FAQ
Q: Can I send you a sample for testing first?
A: Yes, you can. Please contact sales to discuss the purpose of the test, the equipment's operating conditions, and how the sample cost and shipping fees will be shared.
Q: Is it okay to mix old and new hydraulic oil?
A: No. Old oil contains impurities and moisture; mixing it with new oil is the same as not changing it at all. When changing the oil, thoroughly drain and clean the oil tank and lines before adding new oil.
Q: How to choose between the SD5 monolithic design and a comparable segmented design?
A: The SD5 monolithic design has fewer oil leakage points, a smaller size, and a lower price, making it suitable for equipment with fixed functions that don't require modification. Segmented designs are flexible, expandable, and easier to maintain, but they are more expensive and larger. For small equipment where space is already limited, the monolithic design saves more space.
Q: The SD5 has a maximum pressure of 315 bar. What is the actual operating pressure?
A: 315 bar is the maximum withstand pressure. The actual working pressure depends on the equipment's operating conditions. Small loaders, forklifts, and agricultural machinery typically operate at pressures between 200-230 bar. 315 bar provides ample safety margin.
Q: What kind of equipment is the SD5 suitable for?
A: The SD5 is mainly used in equipment such as mini loaders, mini excavators, skid steer loaders, forklifts, tractors, combine harvesters, aerial work platforms, and truck-mounted cranes. It is particularly suitable for small to medium-sized mobile hydraulic systems with limited installation space, clearly defined functions, and no need for future expansion.
