Product Introduction
The DCV200 Hydraulic Directional Valve 200 Liters per Minute 350 bar is a sectional valve for hydraulic systems that require high flow across multiple actuators. It is rated at 200 L/min nominal flow and 350 bar operating pressure, and supports 1 to 12 sections. The mounting center distance is 51 mm, which is larger than the DCV140 and reflects the bigger internal passages needed for its flow class. Manual, pneumatic, and electro-hydraulic control configurations are shown in the hydraulic schematic. The valve body is phosphating treated and tested to a 48-hour neutral salt spray standard. The outline drawing provides the mounting dimensions and indicates an overload valve and an oblique port for a reducing valve.
Control Options
The hydraulic schematic shows three control configurations for the DCV200 Sectional Directional Valve 200 Liters per Minute 350 bar.
Manual control uses a direct lever-to-spool connection. The lever travel is progressive: light resistance at the start, even force through mid-stroke for metering, and a detent click at full open. No electrical power or pilot supply is required.
Pneumatic control uses air pilot pressure to shift the spool. This is relevant where electrical power is unavailable or where a remote control station is preferred.
Electro-hydraulic control uses solenoid pilot valves for automated or joystick-based operation. The control cover is interchangeable; a manual valve can be converted to pneumatic or electro-hydraulic pilot control later without replacing the valve body or working sections.
The standard configuration is manual. Pneumatic and electro-hydraulic versions are specified at the time of order.
Sectional Structure and Installation
The DCV200 uses the same sectional architecture as the rest of the DCV series. An inlet section, working sections, and an outlet section are stacked and held together with through-bolts. Each working section contains its own spool, springs, and detent. The 51 mm mounting center distance is specific to this model.
The valve can be configured with 1 to 12 sections. Each section corresponds to one working circuit. If the machine has six independent hydraulic functions, a six-section valve covers all of them. If a function is added later, a section can be added to the existing stack rather than replacing the entire valve.
The outline drawing indicates an overload valve and an oblique port for a reducing valve. These features allow individual circuits to have their own pressure protection or reduced pressure settings, independent of the main relief valve.

Who We Are
Shijiazhuang Laiye Import & Export Trading Co., Ltd. is part of Hebei Onederful® Hydraulic Technology Co., Ltd. We've been making hydraulic components since 1988 - over 35 years.
We're a factory, not a middleman. Around 200 people work here. We do everything ourselves - casting, machining, assembly, testing, phosphating.
Every valve gets tested individually. Not spot-checked - every single one. The test data goes on file with the serial number. If something comes up years later, we can pull the record.
We ship to more than 20 countries. ISO 9001 certified. We offer OEM customization, technical support, and a 12-month warranty. Test reports, material certificates, and certificates of origin are available on request. If you need documentation, we can provide it. If you need a custom configuration, we can build it. If you need support, we're here.
FAQ
Q: Why choose DCV200 sectional directional valve over DCV140?
A: Flow. DCV140 is 140 L/min. DCV200 is 200 L/min - 43% more flow. If your equipment runs multiple functions simultaneously - boom, bucket, steering, auxiliary - and 140 L/min feels tight, the DCV200 gives you the headroom to keep everything responsive.
Q: What is the difference between DCV200 and DCV140?
A: Flow rating. DCV140 is 140 L/min. DCV200 is 200 L/min. Both are sectional valves with the same pressure rating (350 bar) and leakage spec. The DCV200 has larger internal passages, a larger spool, and a different mounting footprint (51 mm center distance vs 46 mm).
Q: What is a sectional valve?
A: Multiple valve sections bolted together into one stack. Each section controls one function independently. You can add or remove sections as needed.
Q: What is an overload valve and why would I need it?
A: A pressure relief cartridge that mounts to a port on each working section (M10 connection). It lets you set different pressure limits for different functions - high pressure for the bucket circuit, lower pressure for steering. Useful when one valve stack serves multiple actuators with different needs.
Q: What if the valve spool sticks or the actuator doesn't respond?
A: Sticking usually means contamination in the spool bore - dirt, metal particles, or degraded seal material . Flush the valve and check fluid cleanliness (target ISO 4406 18/16/13). If contamination is severe, remove the spool, clean it, and check the bore for scoring
