Why the Proportional Valve Matters for Your Press
In modern ceramic presses the pressing curve — speed, force and position over every cycle — is controlled by proportional valves. A worn or drift-prone proportional cartridge causes slow or unstable pressing cycles, inconsistent tile density and higher rejection rates. Replacing it with a genuine Atos LIQZO-LE-503L4/A restores the original pressing performance and keeps the hydraulic system fully controllable.
Packing & Delivery
The complete valve assembly is packed with protective foam in a reinforced export carton. In-stock orders are dispatched within 1–3 working days; DHL / FedEx express recommended for press downtime emergencies, air and sea freight available.

Which press does this Atos valve fit?
The valve manifold carries the marking SACMI CM 402 · X 50222 · 1120152, matching SACMI hydraulic ceramic presses, and it is also used on HLT / HengLiTai press hydraulic systems. Send us the nameplate photo of your old valve and we will confirm compatibility before ordering.
Is the valve supplied as a complete assembly?
Yes. As shown in the photos, the set includes the LIQZO-LE-503L4/A proportional cartridge (NG50 main stage), the Atos pilot directional solenoid valve, and the digital electronic amplifier with cables — everything mounted and calibrated as one unit for direct installation.
Is it a genuine Atos product?
Yes, 100% genuine Atos original, Made in Italy, with the original nameplate (No. 152121) and serial markings (YM6000735). We only supply original proportional valves for press safety and performance.
What does this valve control on the press?
It is a proportional flow control cartridge valve: the electronic amplifier adjusts the opening of the cartridge proportionally to the input signal, giving precise control of hydraulic flow — and therefore of pressing speed and force profile — during the pressing cycle.
