DCV60 Sectional Directional Control Valve 350 Bar

Shijiazhuang Laiye Import& Export Trading Co., Ltd. is one of the leading manufacturers and suppliers of dcv60 sectional directional control valve 350 bar in China, also supports customized service. If you're going to wholesale high quality dcv60 sectional directional control valve 350 bar made in China, welcome to get pricelist from our factory.

The DCV60 is a sectional directional control valve for mobile and industrial hydraulic systems. It directs oil flow from the pump to multiple actuators - controlling booms, buckets, outriggers, winches, augers, and other hydraulic functions across 1 to 12 independently configurable sections.

Built as a modular sectional body with phosphated surface treatment, the DCV60 is rated at 350 bar continuous pressure and 60 L/min flow, with internal leakage held below 15 cm³/min at 160 bar. It operates across -40°C to +80°C and supports a wide range of control methods - manual, hydraulic, pneumatic, electro-hydraulic, electro-pneumatic, solenoid, joystick, and cable actuation.

Unlike monoblock valves where the body is cast as a single piece, the DCV60 Sectional Directional Control Valve 350 Bar is assembled from individual sections bolted together. Each section controls one hydraulic function. You can specify anywhere from 1 to 12 sections, depending on how many actuators your machine has. Add them as needed. Configure them as required. Service them individually if something goes wrong. That is the core idea behind a sectional valve: flexibility.

Common applications include construction equipment, municipal sanitation vehicles, drilling rigs, and other complex hydraulic systems requiring flexible configuration and serviceability.

DCV60 Sectional Directional Control Valve Specification 

DCV60 sectional directional control valve features

• Sectional design - 1 to 12 configurable sections, expandable and serviceable individually.
• 350 bar pressure - handles heavy loads on excavators, loaders, and drilling rigs.
• 60 L/min flow - matches medium-to-large equipment pump outputs.
• Multiple control options - manual, hydraulic, pneumatic, electric, solenoid, joystick, cable.
• Phosphated surface - 48-hour salt spray corrosion resistance.
• Wide temperature range - -40°C to +80°C, accepts 12–400 cSt viscosity.

Choosing between monoblock and sectional directional control valve

This is not about one being better than the other. It is about the nature of your machine and hydraulic system:

Choose monoblock (P40) when you know your section count will not change, you want a compact package that minimizes space requirements, and you prioritize reducing potential leak paths.

Choose sectional (DCV60) when you need flexibility - multiple sections, potential expansion, individual serviceability, and higher pressure capacity.

DCV60 Sectional Directional Control Valve 350 Bar Applications

We see DCV60 valves in these settings most often:

Construction Equipment
Excavators (10–20 ton class), wheel loaders, backhoe loaders, telescopic handlers, and skid steer loaders. The valve controls boom, arm, bucket, swing, and auxiliary functions - typically 4 to 8 sections on excavators. The 350 bar pressure rating matches the operating pressure of larger mobile equipment in this class.

Municipal Sanitation Vehicles
Street sweepers, refuse trucks, sewer cleaners, and snowplows. These machines have multiple functions - sweeping, vacuum, suction, lifting, dumping, and plow angle control. The DCV60's 1-to-12 section flexibility suits these multi-function vehicles, and the 48-hour salt spray resistance is valuable for winter road maintenance equipment.

Drilling Rigs
Rotary drilling rigs, water well drills, foundation drills, and geotechnical exploration rigs. Drilling operations require precise control over feed, rotation speed, and holdback force. The DCV60 provides the proportional control capability needed for drilling operations, and the high pressure rating supports the loads involved in deep-hole drilling.

Complex Industrial Hydraulic Systems
Material handling systems, steel mill auxiliary hydraulics, and heavy-duty test stands. Where multiple actuators need independent control, sectional valves offer the flexibility to configure the system without custom-engineered manifold blocks.

Attachments
Rotating grapples, concrete breakers, shears, compactors, and augers. These attachments typically run off auxiliary sections on a base machine. The DCV60 can be configured with dedicated attachment sections to suit the specific flow and pressure needs of different tools.

Why choose us?

We started manufacturing hydraulic components in 1988. Over 38 years, we have built a 10,000 square meter production facility, grown our team to over 200 people, and shipped products to customers in more than 20 countries.

What we do in-house

Cast iron sourcing and material verification

CNC machining - section faces, spool bores, port threads, mounting faces

Spool grinding and honing

Section assembly and O-ring installation

Pressure and leakage testing

Phosphating surface treatment

Final inspection and packaging

Quality control - with sectional valves in mind

Sectional valves require particular attention to the mating faces between sections. Each section is inspected for flatness on the mating faces - critical for leak-free assembly. Spools are matched to bores individually, not by batch. The assembly test includes pressure cycling at 350 bar, leakage measurement across all spool positions, and flow performance verification for each section. Test results are documented for each valve serial number.

FAQ

1. What do I need to order upfront if I plan to add sections later?

Order the valve with the maximum expected section count in mind. Specify longer tie rods and end plates that accommodate future additions. The extra sections themselves can be ordered later - they slide into the assembly between existing sections or at the end. We can provide the necessary parts and installation instructions when you expand.

2. How many control methods can I mix on one DCV60 valve?

You can mix different control methods across sections. For example, manual on section 1, hydraulic pilot on section 2, and solenoid on section 3. This is useful when different functions have different control requirements. The sections are independent in this respect. Specify your mixed configuration at order.

3. How does the phosphating surface treatment protect the valve in corrosive environments?

Phosphating is a chemical conversion coating that provides corrosion resistance and a good paint base. The 48-hour salt spray test rating means the valve resists rust for 48 hours of continuous salt spray exposure. This is practical protection for outdoor equipment and coastal environments. For marine or highly corrosive conditions, we recommend additional paint coating.

4. Can I order a single section as a spare?

Yes. We supply individual sections as replacement parts. You can keep one on hand for rapid field service. We recommend specifying the section configuration (spool type, control method, spring rate) to match your existing valve.

5. Is the DCV60 compatible with synthetic hydraulic fluids?

Standard seals are NBR, which works with mineral oil hydraulic fluids. For synthetic fluids, phosphate esters, or water-based fluids, we offer FKM seals and alternative materials. Specify your fluid type when ordering so we select the correct seal material.
