Hitachi Genuine Shuttle Valve (Signal Valve) – 4718274 / YA00000543

Description

Detail Information

1. Key Features & Benefits

• Genuine Hitachi OEM component – Manufactured to Hitachi‘s original equipment specifications. This is a brand‑new, factory‑spec shuttle valve (also known as a signal valve) – not an aftermarket substitute. OEM parts ensure perfect fit, reliable performance, and long service life.

• Precision‑engineered hydraulic control – The shuttle valve is a precision‑engineered hydraulic control component designed to optimize directional flow management in demanding excavation operations. It directs working fluid from the pump to hydraulic cylinders and motors, controlling the direction, speed, and sequence of their movement according to signals from the operator or the control system.

• Reliable pressure balancing and fluid diversion – Featuring a robust, corrosion‑resistant alloy construction with hardened sealing surfaces, this shuttle valve ensures reliable pressure balancing and seamless fluid diversion between hydraulic circuits, even under extreme load cycles.

• Critical signal valve function – As a signal shuttle valve, it plays an essential role in the machine‘s hydraulic control system, ensuring that pilot pressure signals are correctly routed to activate the main control valve spools. This enables precise, responsive machine operation.

• Heavy‑duty construction for demanding applications – Manufactured with high precision and well‑fitted internal components, this shuttle valve is specifically designed for heavy‑duty working scenarios in construction, mining, and quarrying environments.

• Wide compatibility across Hitachi Zaxis series – Compatible with a broad range of Hitachi excavator models including ZX200‑5, ZX240‑5, ZX330‑5G, ZX330, ZX470, ZX870, as well as ZX160LC‑3, ZX200‑3, ZX200‑5G, ZX210K‑3, ZX225US‑3, ZX240‑5G, and many others.

• Multiple interchangeable part numbers – This valve is available under part numbers 4718274 and YA00000543, which are interchangeable variants used across different production batches and model variants.

• Pre‑shipment visual verification – Before packing, we send you detailed high‑resolution photographs of the actual unit (part number markings, sealing surfaces, overall condition). You approve shipment – we never ship blind. Video inspection is also available upon request.

• Fast delivery – 5–7 working days lead time from our Guangzhou warehouse. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight.

2. Applications

The Hitachi shuttle valve (4718274 / YA00000543) is a critical hydraulic control component for Zaxis series excavators used across a wide range of demanding job sites:

• Large‑scale mining & quarrying – In open‑pit mines and aggregate quarries, excavators work 20+ hour shifts under extreme loads. The shuttle valve ensures reliable pressure balancing and seamless fluid diversion between hydraulic circuits, maintaining consistent machine performance even under extreme load cycles. Its robust, corrosion‑resistant alloy construction withstands the harsh, dusty conditions of mining environments.

• Heavy construction & earthmoving – Highway excavation, dam building, bridge footings, and large‑scale earthmoving projects demand precise, responsive hydraulic control. The shuttle valve routes pilot pressure signals to activate the main control valve spools, enabling smooth, coordinated machine movements – from delicate grading to heavy bucket loads.

• Demolition & scrap processing – Shock loads, vibration, and rapid load changes are routine in demolition yards and metal recycling facilities. The shuttle valve‘s hardened sealing surfaces and precision‑engineered internal components ensure reliable performance under these extreme conditions.

• Urban construction & utilities – Sidewalk repairs, trenching, and small‑scale demolition in tight urban spaces require precise machine control. The shuttle valve ensures that hydraulic signals are accurately routed, providing the “fine‑touch” response needed for working near existing structures.

• Equipment rental fleet – 20–87 ton excavators are high‑value rental assets. A genuine new shuttle valve provides predictable performance and eliminates the risk of hydraulic control failure – avoiding costly mid‑rental breakdowns and customer complaints.

3. FAQ – Frequently Asked Questions

Q1: Is this shuttle valve an exact replacement for my Hitachi excavator?

A: Yes. The 4718274 and YA00000543 are genuine Hitachi shuttle valves compatible with ZX200‑5, ZX240‑5, ZX330‑5G, ZX330, ZX470, ZX870, and many other Zaxis series excavators. To confirm compatibility for your specific machine, send us your machine serial number and a photo of the old valve – we will verify within 2 hours.

Q2: What is the difference between a shuttle valve and a signal valve?

A: These terms are often used interchangeably for this component. The shuttle valve (also called a signal valve) routes pilot pressure signals from the control system to activate the main control valve spools, directing hydraulic flow to the appropriate circuits. It ensures that the machine responds accurately to operator joystick inputs.

Q3: Is this a new valve or a remanufactured unit?

A: It is brand new / genuine original, not remanufactured. All internal components are new. The valve is manufactured to Hitachi‘s original specifications and meets all OEM performance standards.

Q4: What are the physical specifications of this valve?

A: The valve dimensions are approximately 28 × 29 × 30 cm and it weighs approximately 15 kg. It is constructed from a robust, corrosion‑resistant alloy with hardened sealing surfaces.

Q5: What is the warranty on this valve?

A: The warranty period is 3 months. Please refer to the product details for full warranty terms. For customers who require extended warranty coverage, we can quote aftermarket alternatives – ask our sales team.

Q6: How long does delivery take?

A: Delivery is 5–7 working days after order confirmation. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight are available.

Q7: What payment methods do you accept?

A: We accept T/T (wire transfer), Western Union, and PayPal.

Q8: How can I verify the valve is genuine before shipping?

A: Before packing, we send you clear, high‑resolution photographs of the actual unit – part number markings, sealing surfaces, and overall condition. You approve shipment only after reviewing these images. We never ship blind. Video inspection is also available upon request.
