ATOS RZGO-A-033/315 31 Piloted Proportional Pressure Reducing Valve

Product Name: ATOS RZGO-A-033/315 31 Piloted Proportional Pressure Reducing Valve
Model Number: RZGO-A-033/315 31
Brand: ATOS
Product Type: Pilot-operated proportional pressure reducing valve
Series: RZGO
Mounting: Subplate
Nominal Size: NG06 / ISO 4401 Size 06

Product Overview

The ATOS RZGO-A-033/315 31 is a pilot-operated proportional pressure reducing valve designed for electronically adjustable hydraulic pressure control. It belongs to the ATOS RZGO series of proportional pressure reducing valves and uses a size 06 ISO 4401 subplate mounting interface. (Atos)

The 033 configuration is specifically used for pressure regulation on port A with discharge to T, and the 315 designation identifies the 315 bar maximum regulated-pressure version. (Atos)

The valve is suitable for industrial hydraulic systems where accurate and continuously adjustable pressure control is required.

Model Number Breakdown

RZGO-A-033/315 31

Code	Meaning
RZGO	Piloted proportional pressure reducing valve, subplate mounting, size 06
A	Off-board electronic driver configuration
033	Pressure regulation on port A, discharge to T
315	Maximum regulated pressure range: 315 bar

ATOS documentation confirms that RZGO valves are available in size 06 and that configuration 033 is the RZGO configuration for regulation on port A. (Atos)

Product Details

The RZGO-A-033/315 31 provides proportional hydraulic pressure regulation according to an electrical command signal when used with the appropriate ATOS electronic driver.

Its pilot-operated design makes it suitable for applications requiring electronically controlled hydraulic pressure rather than simple fixed-pressure adjustment.

Important: The complete electrical configuration should be confirmed from the valve nameplate before ordering. ATOS offers different coil/driver options, including standard 24 VDC-driver coils, 12 VDC options and low-current-driver options. (Atos)

Hydraulic Characteristics

For the RZGO-A family, ATOS documentation gives the following general performance data:

• Maximum regulated pressure: available versions include 50, 100, 210, 315 and 350 bar

• Minimum regulated pressure: approximately 1 bar or actual pressure at the T port

• Maximum flow: 40 L/min

• Minimum flow: 2.5 L/min

• Response time: ≤50 ms for a 0–100% step signal, depending on installation

• Hysteresis: ≤2% of maximum regulated pressure

• Linearity: ≤3% of maximum regulated pressure

• Repeatability: ≤2% of maximum regulated pressure (Scribd)

These are series-level hydraulic characteristics, not necessarily individual guaranteed performance values for every installation.

Applications

The ATOS RZGO-A-033/315 31 can be used in:

• Industrial hydraulic machinery

• Manufacturing equipment

• OEM hydraulic machines

• Machine tools

• Pressing machinery

• Plastic and injection machinery

• Hydraulic power units

• Material handling equipment

• Metalworking machinery

• Automated hydraulic systems

• Applications requiring electronically adjustable pressure

Why Choose a Proportional Pressure Reducing Valve?

A proportional pressure reducing valve allows the hydraulic system pressure to be adjusted electronically rather than only through a manual mechanical adjustment.

This is useful when the machine controller needs to change hydraulic pressure according to:

• Machine operating cycle

• Load conditions

• Production process

• Position or speed requirements

• PLC or electronic control commands

For systems requiring automated pressure control, the RZGO series can therefore provide a more flexible solution than a conventional fixed-pressure reducing valve.

Alternative Models

Depending on the required hydraulic circuit and control method, possible alternatives within the ATOS range include:

• RZGO-A-033/210 31 – lower pressure version

• RZGO-A-033/350 31 – higher pressure version

• HZGO-A-031 – modular size 06 configuration

• KZGO-A-031 – modular size 10 configuration

Do not substitute these models solely based on pressure rating. Port configuration, mounting arrangement, electrical control, flow requirement and system design must be checked before replacement. ATOS identifies RZGO as subplate size 06, HZGO as modular size 06 and KZGO as modular size 10. (Atos)

FAQ
