When Is NG16 (10-Size) Required?

The most common and costly mistake in hydraulic manifold specification is undersizing the valve interface. Machine builders frequently default to NG10 (CETOP 5) blocks because they are cheaper and more readily available — then wonder why their machines run hot, cycle slowly, and suffer premature valve failure.

The rule is simple: If your circuit flow rate exceeds 80 LPM at the directional valve, you must use NG16 or larger.

Common scenarios requiring NG16:

Large-bore cylinders: A 160mm bore cylinder extending at 0.1 m/s requires ~200 LPM. Routing 200 LPM through an NG10 block creates 15+ m/s fluid velocity — this is catastrophic for the valve and the system.
Multiple small cylinders on one valve: If one directional valve serves two or three cylinders simultaneously, the combined flow demand may exceed NG10 capacity.
High-speed automation: Presses and handling equipment requiring rapid cylinder travel speeds generate high peak flow demands that exhaust NG10 capacity.
Long-stroke cylinders: Large fluid volume requirements per cycle may not cause velocity problems but create temperature issues in NG10 blocks with their smaller T gallery cross-sections.

NG16 Technical Specifications & Performance Envelope

The NG16 interface is designed to handle up to 250 LPM without causing restrictive pressure drops. Proper port sizing and internal gallery dimensioning is critical at these flow rates.

Material Selection Guide for Heavy Industry

NG16 blocks are predominantly used in heavy industrial environments where material selection is critical. Ductile Iron is frequently specified for NG16 blocks in forging and heavy-press environments because its damping characteristics absorb the pressure pulsations generated by large displacement gear pumps.

General factory floor	Aluminium 6061-T6 (anodized)	210 Bar
Heavy press rooms, heat	ST52 Carbon Steel (zinc plated)	315 Bar

NG16 Product Range

Single-StationNG16 Single-Station Subplates

For single-cylinder, high-flow applications. Standard configuration with G3/4" P and T ports. Available with SAE Code 61 flange option for very high-flow connections. Aluminium (up to 210 Bar) or ST52 Steel (up to 315 Bar).

Multi-StationNG16 Multi-Station Manifold Rails

2 to 6-station parallel rails. The physical size of NG16 blocks limits practical multi-station rails to 6 stations before the block length exceeds manageable dimensions. For 6+ high-flow stations, we recommend our custom manifold block approach with integrated cartridge valves.

SandwichNG16 Sandwich Subbase Plates

Extended subbase plates for stacking pressure-reducing and flow-control sandwich modules between the base and the directional valve. Useful for complex, multi-pressure circuits driving large cylinders.

OEM Case Study

NG16 4-Station Manifold Block for Hydraulic Goods Lift

Material Handling Equipment Builder — Odhav GIDC, Ahmedabad

The Challenge

A 10-tonne capacity hydraulic goods lift using four 200mm bore cylinders was suffering from premature valve seal degradation and synchronization hunting. Their previous design used four separate NG10 CETOP 5 blocks which were grossly undersized for the flow.

The Solution

We redesigned the logic around a single 4-station NG16 manifold block in ST52 steel. The enlarged galleries eliminated velocity-induced pressure drops, and we integrated proportional flow-control cartridges per station directly within the block body.

The Outcome

System operating temperature dropped by 22°C. The platform achieved ±1.2mm synchronization accuracy. The client standardized NG16 architecture across their entire heavy goods lift range.

Calculate your maximum circuit flow: bore (m)² × π/4 × velocity (m/s) × 60,000 = LPM. If this exceeds 80 LPM, specify NG16. If it exceeds 200 LPM, specify CETOP 8 (NG22).

No. The bolt patterns, port locations, and O-ring sizes are completely different between sizes. Each CETOP size is a distinct, non-interchangeable interface.

We maintain buffer stock of standard NG16 single-station subplates in both aluminium and steel. Standard configurations (G3/4" BSPP ports) can typically be despatched within 3–5 working days.

Ductile iron (GGG50) is a cast iron alloy with superior mechanical toughness and excellent vibration damping compared to steel. For high-flow circuits driven by gear pumps (which produce significant pressure pulsation), ductile iron blocks absorb the pulsation energy, reducing stress fatigue on valve body seals and extending the overall system service life.
