1. Key Features & Benefits

• Professionally remanufactured to Caterpillar OEM specifications – This main control valve (OEM 316-2157) has been fully disassembled, cleaned, crack‑inspected, and rebuilt to meet Caterpillar’s original equipment specifications. Every critical component – spools, sleeves, springs, seals, O‑rings, and relief valves – 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.

• The hydraulic “brain” of your CAT 313 excavator – The main control valve is the central component that directs high‑pressure oil from the main pump to the boom, arm, bucket, swing, and travel circuits based on the operator‘s joystick inputs. It determines the direction and speed of implement cylinders and motors in proportion to joystick and travel pedal movement. When this valve wears out, your machine loses precision, power, and responsiveness.

• Direct replacement for CAT 313 and compatible models – Specifically engineered for Caterpillar 313, 313D, 313F, 313GC, and related 13‑ton class excavators. Mounting flange, port configurations, and bolt patterns match the original Caterpillar specifications exactly – no modifications, no adapters.

• Advanced electro-hydraulic control – The 313 series features an updated main control valve with electro-hydraulic pump control that eliminates the need for pilot lines, reduces pressure losses, and lowers fuel consumption. Two power modes help minimize fuel use while maintaining responsive machine performance.

• High‑pressure capability for 13‑ton class work – Designed for the CAT 313 hydraulic system with a main relief pressure of 30.5 MPa (≈4,425 psi) , travel circuit pressure of 35 MPa (≈5,076 psi) , and swing circuit pressure of 23 MPa (≈3,336 psi) . The main pump delivers a maximum flow of 127 L/min.

• Precision‑machined spools for smooth, accurate control – Every control spool is precision‑ground to exacting tolerances, ensuring smooth spool shifting and accurate flow metering. This delivers the precise, predictable machine response that CAT excavators are known for – critical for precision grading, trenching near utilities, and fine attachment control.

• Integrated circuit protection – Features built‑in main relief valves to protect the hydraulic system from overpressure, overload relief valves with make‑up function to prevent cavitation during sudden load changes, and boom and stick drift reduction valves for load holding safety.

• Superior durability and contamination resistance – Utilizes high‑strength alloy materials and precision‑machined spools and sleeves with tolerances measured in microns 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 Caterpillar 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 CAT 316-2157 main control valve is the hydraulic command centre for 13‑ton class excavators used across a wide range of job sites:

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

• Residential & commercial development – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The valve’s smooth, predictable response and precise metering characteristics allow operators to work efficiently in confined spaces.

• Road & bridge maintenance – Shoulder repairs, guardrail replacement, and drainage cleaning. The valve’s consistent flow delivery allows operators to position attachments precisely for roadside work, even in tight work zones with limited space.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling. The valve’s robust construction and high‑pressure capability (30.5 MPa main relief) withstand abrasive dust conditions and heavy loads.

• Equipment rental fleet – 13‑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. FAQ – Frequently Asked Questions

Q1: Is this main control valve an exact replacement for my CAT 313?

A: Yes. The 316-2157 is the genuine Caterpillar main control valve for CAT 313, 313D, 313F, 313GC, and compatible 13‑ton class excavators. To confirm compatibility for your specific machine variant, send us your machine serial number and a photo of the old valve nameplate – we will verify within 2 hours.

Q2: Is this a new valve or a remanufactured unit?

A: This is a professionally remanufactured valve. All internal wear components (spools, sleeves, seals, O‑rings, springs) are replaced or re‑ground to OEM specs. The result is a valve that performs like new – at a fraction of the cost. We do not sell “compatible” substitutes – you receive a valve that matches the original in every measurable dimension.

Q3: What are the key specifications of this valve?

A: The 316-2157 main control valve is engineered for the CAT 313 hydraulic system with a main relief pressure of 30.5 MPa (≈4,425 psi), travel circuit pressure of 35 MPa (≈5,076 psi), and swing circuit pressure of 23 MPa (≈3,336 psi). The main pump delivers a maximum flow of 127 L/min. The valve features electro-hydraulic control, boom and stick drift reduction valves, and integrated main relief and port relief protection.

Q4: What is the warranty on this valve?

A: 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.

Q5: How long does delivery take?

A: Delivery is 5–8 working days after order confirmation from our Guangzhou warehouse. Express shipping (DHL/FedEx/UPS) is available for urgent orders.

Q6: What payment methods do you accept?

A: We accept L/C, T/T, XTransfer, PayPal, and Western Union.

Q7: How can I verify the valve is ready before shipping?

A: Before packing, we send you clear, high‑resolution photographs of the actual unit – mounting surfaces, spools, port threads, casting marks, and overall condition. You approve shipment only after reviewing these images. We never ship blind.

Q8: What should I check before installing a remanufactured main control valve?

A: Before installation, flush the entire hydraulic system and replace all filters to remove contaminants. Check pilot pressure (typically 3–4 MPa) to ensure proper spool shifting. Use new O‑rings and sealing washers on every connection. 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. Verify main relief and port relief pressures are set to Caterpillar factory specifications.
