ZD Series Round Differential Hydraulic Cylinders
Watz ZD round differential hydraulic cylinders operate at a nominal pressure of 160 bar, providing dependable linear actuation for machine tools, stamping presses, and plant automation systems.
Threaded front and rear cylinder heads ensure compact external dimensions and structural stability under continuous vibrations and alternating mechanical stresses.
ZM Series Heavy-Duty Round Cylinders for 250 Bar
The Watz ZM series is engineered for demanding industrial environments including steelworks and forging lines requiring operating pressures up to 250 bar.
High-grade alloy steel rods undergo induction hardening and heavy hard-chrome plating, delivering outstanding protection against abrasive particle wear and lateral bending moments.
ZB Series Compact High-Pressure Block Cylinders
Watz ZB block cylinders operate at pressures up to 500 bar and are designed for space-restricted tooling, plastic injection molds, and hydraulic clamping fixtures.
High-tensile forged steel monobloc bodies absorb peak dynamic shock waves during rapid mold closing cycles while optional inductive sensors provide position verification.
Custom Industrial Hydraulic Power Units and Stations
Watz Hydraulik engineers and builds turnkey fluid power systems matched to precise volumetric flow, operating pressure, and thermal balance specifications.
Fabricated fluid reservoirs built to DIN 24339 standards scale up to 32,000 liters, featuring variable displacement pumps, high-efficiency heat exchangers, and multi-stage filtration.
Hydro-Service Large-Bore and Special Long-Stroke Cylinders
Through its specialized Hydro-Service Zylinderbau division, Watz manufactures large-dimension cylinders featuring bore diameters up to 1,200 mm and stroke lengths up to 12,000 mm.
These heavy-duty hydraulic actuators power weir gates, navigation locks, movable bridges, offshore platforms, and primary metals rolling mills worldwide.
Integrated 3D Hydraulic Manifolds and Control Blocks
Watz custom hydraulic manifold blocks use optimized internal flow channels to mount directional, proportional, and pressure relief valves without external plumbing.
High-density solid steel blocks eliminate leakage hazards at system pressures up to 400 bar while reducing hydrodynamic fluid friction across continuous production cycles.
