1. Key Features & Benefits

• Professionally remanufactured to Hitachi OEM specifications – This main control valve (MCV) has been fully disassembled, cleaned, crack‑inspected, and rebuilt to meet Hitachi’s original equipment specifications. Every critical component – spools, sleeves, springs, seals, O‑rings, and gaskets – is either renewed or replaced with new, high‑quality parts. The result is restored hydraulic performance at a fraction of the cost of a new genuine valve.

• Direct replacement for Hitachi EX200-1 series excavators – Specifically engineered for Hitachi EX200-1, EX200K-1, EX220-1, EX270-1, EX300-1, and EX400-1 excavators. This main control valve is the hydraulic “brain” of your excavator, directing flow from the main pump to the boom, arm, bucket, swing, and travel circuits.

• Open‑centre hydraulic design – The EX200‑1 utilises an open‑centre control valve architecture. All pump flow, regardless of whether the pumps are at minimum or maximum stroke, returns through the centre passage of the control valve and back to tank. This design requires precise spool tolerances and sealing integrity to maintain proper machine response.

• Critical hydraulic system component – The main control valve governs every movement your machine makes – from a delicate grading pass to a heavy bucket curl. According to Hitachi’s hydraulic system architecture for the EX200 series, the control valve distributes hydraulic pump flow to each actuator while controlling speed, direction, and force. When internal seals degrade, the result is internal leakage, pressure drops, slow response, or poor machine control. The valve features built‑in main relief valves and overload relief valves to control circuit maximum pressure. A remanufactured valve restores the factory‑spec flow and pressure characteristics your EX200‑1 was designed for.

• Restored 20‑ton class hydraulic performance – After remanufacturing, this valve delivers the full rated flow and pressure your EX200‑1 was designed for. Your excavator regains smooth, precise control, fast cycle times, and consistent attachment power – eliminating the sluggish, jerky, or unpredictable performance caused by internal wear and leakage.

• Superior durability and contamination resistance – Utilises high‑strength alloy materials and precision‑machined spools and sleeves to ensure minimal internal leakage and maximum control precision. Premium seals and O‑rings are installed to withstand extreme pressures and temperatures.

• Direct bolt‑on replacement – Mounting flange, port configurations, and bolt patterns are restored to original Hitachi specifications. No modifications, no adapters – your mechanic unbolts the old valve and bolts this one in.

• Pre‑shipment visual verification – Before packing, we send you detailed high‑resolution photographs of the actual unit (mounting surfaces, port threads, castings, overall condition). You approve shipment – we never ship blind.

• Fast delivery – 5–8 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 300 units, available for single‑piece or bulk orders.

2. Applications

The remanufactured Hitachi EX200‑1 main control valve is the hydraulic command centre for this 20‑ton class excavator used across a wide range of job sites:

• Heavy construction & infrastructure – Highway excavation, dam building, bridge footings, and large‑scale earthmoving projects. The valve’s precise flow control enables efficient loading and digging cycles.

• Urban construction & utilities – Sidewalk repairs, water and gas line trenching, and small‑scale demolition. The valve’s precise flow control provides “fine‑touch” response for delicate digging near existing structures while delivering enough power for breaking compacted surfaces.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries. The valve’s robust construction withstands abrasive dust conditions.

• Equipment rental fleet – 20‑ton excavators are frequently rented machines. A remanufactured main control valve offers predictable performance at a cost that makes proactive replacement financially sensible – avoiding costly mid‑rental failures, towing bills, and customer complaints.

• Forestry & vegetation clearance – Steep slopes, fallen timber, and uneven terrain demand reliable hydraulic control. The valve’s consistent pressure and flow output maintain stable power for saws, grapples, and mulchers.

3. Why Choose Hongtengda Parts

Since 2001, Hongtengda Parts has been a leading distributor of earthmoving machinery parts, serving customers across Southeast Asia, the Middle East, Africa, the Americas, and Oceania. Headquartered in Guangzhou’s Zhucun parts hub – one of Asia’s major distribution centres for construction machinery parts – we combine deep inventory, cross‑brand knowledge, and reliable global shipping to keep your machines running.

What you get when you order from us:

• 25 years of heavy equipment parts experience – Since 2001, we have been the go‑to supplier for repair shops, fleet owners, and wholesalers worldwide. We know the Hitachi EX200‑1 platform inside out – the different hydraulic systems, control configurations, and production changes over the years.

• Remanufacturing that delivers performance comparable to new – Our remanufacturing process follows strict quality standards to ensure same‑as‑new quality and performance. Each main control valve is rebuilt using precision engineering principles, with all critical wear components replaced – not just patched or resealed. Every spool tolerance is examined and measured to ensure OEM specifications are met.

• 90% of our catalog in stock – Your main control valve sits in our Guangzhou warehouse, not in a supplier‘s backlog. From hydraulic components to undercarriage kits, most orders are dispatched within 24 hours on fumigated, export‑ready pallets.

• One supplier, all parts – Got a serial number, a model code, or just a photo of a worn‑out part? Our specialists cross‑reference across Hitachi, Caterpillar, Komatsu, Sany, and 15+ brands to find what you need. OEM, OEM‑quality, or hard‑to‑find older model parts – we handle the search so you don’t have to.

• Own maintenance factory and technical team – Equipped with our own maintenance factory and a team of experienced technicians, we provide global customers with one‑stop solutions covering parts supply, technical support, and equipment maintenance.

• Pre‑shipment verification – We never ship a main control valve blind. You receive clear photos of the actual unit before packing – you approve, we ship. When downtime costs money, we move at your speed.

• After‑sales support that works – Three senior technicians review your case together. If it‘s a quality issue – we cover it. If not – we still guide you through the fix. We don’t just sell parts; we keep you running.

Critical installation tip for the EX200‑1 main control valve:
– Hydraulic system cleanliness is critical. Before installing the remanufactured valve, flush the entire hydraulic system and replace all filters. Contaminants from a failed valve will destroy a remanufactured unit just as quickly as a new one.
– Pilot pressure must be checked – Low pilot pressure prevents main control valve spool shifting. Ensure pilot pressure is within Hitachi factory specifications before connecting the new valve.
– Use new O‑rings and sealing washers on every hydraulic connection. Reused seals guarantee leaks.
– Bleed air from the system – After installation, run the engine at low idle for 2‑3 minutes, then slowly cycle each function (boom, arm, bucket, swing, travel) to purge air from the circuit.
– Check all relief valve settings – Verify main relief and port relief pressures are set to Hitachi factory specifications.

Warranty note: Warranty period is 3 to 6 months depending on product details. We do not provide warranty service for original used or remanufactured parts. Our value is delivered up front: careful remanufacturing, thorough testing, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote new aftermarket units – ask our sales team.
