HydroControl HC-M45/5-IR301-(160)W001H001F001*5-AG02 is a directional control valve hydraulic with manual hydraulic control valve functionality,rated for 35 MPa and 45 L/min flow,designed for demanding industrial and mobile hydraulic systems.

　　Product Type Definition

　　A directional control valve is a hydraulic component that directs fluid flow to different actuators within a system,controlling the start,stop,and direction of motion.These valves are categorized by the number of ports,spool positions,and actuation method.The HC-M45/5-IR301 falls into the manually operated,direct-acting spool valve category,characterized by its compact monoblock construction with five sections,each featuring a spring-centered,three-position spool for precise flow control in multi-actuator circuits.

　　Key Specifications

　　Rated pressure:35 MPa

　　Rated flow:45 L/min

　　Control method:Manual(lever-operated)

　　Number of sections:5

　　Oil port size(P,A,B,T):G3/8"(BSPP)

　　Spool type:Spring-centered,three-position

　　Seal material:NBR(standard,suitable for mineral oils)

　　Mounting:Monoblock valve body with through-bolt mounting holes

　　Technical Highlights

　　Manual control with detent options:The manual lever provides direct,tactile feedback to the operator,essential for applications requiring precise,gradual flow modulation.Each spool section features a spring return to center,with optional detent kits available for maintaining a selected spool position without continuous operator input,improving usability in sustained operations.

　　High power density:The valve achieves a 35 MPa rated pressure within a compact monoblock casting,enabling high force output in space-constrained installations common on mobile equipment and shipboard hydraulic power units.

　　Parallel circuit configuration:The five-section monoblock routes supply oil from the P port in parallel to all sections,allowing simultaneous or independent operation of up to five actuators.This architecture minimizes pressure drop across the bank,maintaining consistent actuator speed under combined loads.

　　Corrosion-resistant material treatment:The cast iron body undergoes a phosphate coating process,providing a base layer that exceeds 200 hours of salt spray resistance per ISO 9227,extending service life in marine and outdoor environments.

　　Applications

　　Metallurgical industry hydraulic systems:Delivers consistent flow control for roll adjustment,material handling,and furnace door actuation where reliable manual override is required during maintenance or emergency operations.

　　Marine hydraulic systems:With G3/8"BSPP ports compatible with common marine fittings and corrosion-resistant coating,the valve reliably operates deck machinery,hatch covers,and crane outriggers in high-humidity,salt-laden environments.

　　Mobile hydraulic equipment:The 45 L/min flow capacity matches the hydraulic power range of compact wheel loaders,skid steers,and telescopic handlers,providing proportional control for attachment functions such as grapples,augers,and tilt cylinders.

　　Engineering equipment hydraulics:Suitable for service vehicles,drilling rigs,and material lifts where a single operator needs direct,independent control of multiple hydraulic circuits without reliance on electrical solenoids.

　　Selection Guidance

　　Suitable for:Systems requiring up to five independent hydraulic functions with manual lever actuation,particularly where electrical power for solenoid valves is unavailable or where fail-safe manual operation is a design requirement.

　　Suitable for:Mobile and industrial applications with a maximum operating pressure of 35 MPa and flow demands up to 45 L/min per section,using mineral-based hydraulic fluids(ISO VG 32 to 68).

　　Not recommended for:High-frequency automated cycles requiring programmable logic control(PLC)integration.For such applications,consider solenoid-operated or proportional valves with the same monoblock footprint but equipped with electrical coils and position feedback.

　　Not recommended for:Systems using water-glycol or phosphate ester fluids without confirming seal compatibility.The standard NBR seals are not suitable;alternative FKM seals should be specified.

　　FAQ

　　1.What is the maximum operating pressure for the HC-M45/5-IR301?

　　35 MPa(350 bar).The valve body and internal spool are designed to withstand this pressure continuously,with a proof pressure of 52.5 MPa(1.5x rated)per ISO 9001-manufacturing test protocols.

　　2.What fluid compatibility does the valve offer?

　　Standard NBR seals are compatible with mineral oils and synthetic hydrocarbon-based hydraulic fluids.For applications using phosphate esters or water-glycol fluids,FKM seals must be specified at the time of order.

　　3.Can this valve be operated in low-temperature environments?

　　Yes,the manual lever mechanism maintains consistent operation down to-20°C with the appropriate low-viscosity hydraulic fluid(ISO VG 22).Below this temperature,increased spool resistance may require higher lever force,and a cold-start fluid warmer is recommended.

　　4.What is the recommended maintenance interval?

　　Inspect lever linkage and mounting bolts every 1,000 operating hours or annually.The internal spool and seals typically exceed 10,000 cycles under rated conditions with clean fluid meeting ISO 4406 cleanliness class 18/16/13,as validated in accelerated life testing.

　　5.How does this five-section monoblock compare to using five individual sectional valves?

　　The monoblock design eliminates external interconnecting hoses between sections,reducing potential leak points by up to 80%compared to stacked sectional valves.It also provides a more compact installation with single mounting footprint.
