Product Overview & Model Decoding

The YZA series is a family of compact, self-contained electro-hydraulic power units built around a constant-pressure pump + integrated valve manifold. The YZA15-8 is the mid-size, most-ordered member: enough flow for several medium brakes or a bank of rail clamps, small enough to bolt onto a crane walkway or inside a cabinet.

Code segment	Meaning	YZA15-8 value
YZ	YZ-series hydraulic unit	YZ family
A	Design type A (standard, foot-mount)	Standard footprint
15	Rated pressure class = 15 MPa (adjustable 8–15 MPa)	150 bar
8	Rated flow = 8 L/min (8 Lpm)	8 Lpm @ rated pressure
/ …	Optional suffix (motor voltage / tank / valves / Ex)	Negotiable per order

Naming decoded: "15" = 15 MPa (not 15 Lpm, not 15 kW). "8" = 8 Lpm (not 8 MPa). Pressure and flow are the two independent sizing axes - see Section 7 to size correctly.

YZA / YZB Family Selection Table

Model	Pressure	Flow (Lpm)	Motor	Tank	Best for
YZA10-8	10 MPa	8	2.2 kW	25 L	Single small SBD / one rail clamp
YZA15-8	15 MPa	8	3 kW	40 L	THIS PRODUCT - 2–6 brakes / clamps
YZA15-14	15 MPa	14	4 kW	60 L	Medium disc-brake bank, faster cycles
YZB14-20	14 MPa	20	5.5 kW	80 L	Heavy SBD bank / multi-leg gantry
YZB20-40	20 MPa	40	11 kW	160 L	Large hydraulic brake systems, steel mill

The rule: within the same pressure class, higher flow = faster release & more brakes per second. Stay at 15 MPa and move from 8 → 14 Lpm when cycle time or brake count grows.
