Counterbalance valves

In hydraulic systems, controlling pressure and flow is critical to ensure stability, safety, and performance.
Components such as hydraulic balancing valves, oil control valves, and counterbalance valvesare essential to maintain proper system behavior.

Whether you are working with a hydraulic balancing valve, a single counterbalance valve, or a Bosch Rexroth oil control counterbalance valve, choosing the right solution directly impacts system efficiency and reliability.

At OCGF, we support professionals with expert guidance, high-quality components, and fast worldwide delivery.

Balancing valves

OCGF is the reference in the field of hydraulic components, especially in the range of balancing valves. 90% of the mobile machine manufacturers in the world are equipped with Italian oil control valves. Today the name is Oil Control Bosch Rexroth. This product takes into account the ISO 8643 standard that is to say it holds the load if there is a hose break. This balancing valve has the function of retaining the load in the event of a driving load or during a bursting of the hose. In-line mounting, flange or banjo, directly on the hydraulic cylinder, you also find it in aluminum or steel.

The safety valve  is a standard in the field of public works such as excavators, loaders and all material handling. In the industry the balancing valve has mainly a load retaining function with a regenerative option. A check valve can be compensated or compensated in full depending on the desired function

The highly precise manufacturing of Rexroth oil control bosch offers a 100% tested balancing valve to ensure a compliant part. For 40 years the basic code is VBSO or A VBSO this marking makes it easy to recognize an OIL CONTROL balancing valve.

OCGF has all the skills and expertise to determine the most suitable hydraulic component  for the application.

What is a hydraulic balancing valve?

A hydraulic balancing valveis designed to regulate and maintain consistent pressure and flow distribution within a hydraulic system.

It directly influences:

• differential pressure control

• flow rate distribution

• system stability and load balance

Depending on the application, it may also be referred to as:

• flow balancing valve (focus on flow control)

• hydronic balancing valve (used in heating and cooling systems)

Important: Do not confuse a balancing valve with a counterbalance valve, which is used for load holding rather than system balancing.

In short: a hydraulic balancing valve ensures uniform pressure and flow, preventing system imbalance and inefficiencies.

What is a counterbalance valve (oil control valve)?

A counterbalance valve, also known as an oil control valve, is designed to control load movement and prevent uncontrolled motion in hydraulic systems.

You may encounter terms such as:

• oil control counterbalance valve

• single counterbalance valve

• counterbalance valve Rexroth

• Hydraulic Counterbalance valves - Bosch Rexroth Oil Control

These valves are commonly used to:

• hold loads in position

• prevent free fall

• control actuator movement

In short: a counterbalance valve controls load stability, while a balancing valve regulates system pressure.

Hydraulic balancing valve vs counterbalance valve

Understanding the difference is essential for proper system design.

In short: balancing valves stabilize the system, while counterbalance valves secure the load.

How does an oil control counterbalance valve work?

An oil control counterbalance valveoperates by maintaining back pressure on a load to prevent uncontrolled movement.

When pressure conditions change:

• the valve modulates flow

• maintains load control

• prevents sudden drops

Typical features include:

• pilot-operated mechanism

• pressure setting adjustment

• integrated check function

In short: it ensures controlled motion and load safety in hydraulic systems.

How to choose between a balancing valve and a counterbalance valve?

Choosing the right component depends on your application.

Choose a hydraulic balancing valve if you need:

• pressure stabilization

• flow distribution

• system-wide regulation

Choose a counterbalance valve if you need:

• load holding

• motion control

• safety against free fall

Key technical criteria:

• operating pressure

• flow rate (Cv / Kvs)

• load characteristics

• system configuration

In short: balancing = system control, counterbalance = load control.

H2: Standards and quality (Bosch Rexroth Oil Control)

High-quality valves, such as Hydraulic Counterbalance valves - Bosch Rexroth Oil Control, meet strict industrial standards.

Key standards:

• EN 837

• ISO 9001

Using recognized manufacturers like Bosch Rexrothensures:

• high reliability

• consistent performance

• long service life

In short: certified valves from trusted brands guarantee safety and durability.

H2: Applications of balancing and counterbalance valves

These valves are widely used across industries:

Industrial hydraulics:

• hydraulic power units

• industrial machinery

• process systems

Mobile hydraulics:

• lifting systems

• construction equipment

• agricultural machinery

HVAC / hydronic systems:

• heating circuits

• cooling systems

Example:

A lifting system requires a single counterbalance valveto prevent load drop, while a balancing valve ensures stable pressure across the circuit.

In short: both valve types are complementary in complex systems.

H2: Common mistakes to avoid

Incorrect valve selection can lead to serious issues.

Frequent mistakes:

• confusing balancing valve with counterbalance valve

• incorrect pressure settings

• undersized flow capacity

• poor installation location

In short: proper understanding and sizing are critical for system safety.

H2: FAQ – Frequently Asked Questions

What is an oil control valve?

An oil control valve is another term for a counterbalance valve used to control load movement in hydraulic systems.

What is a single counterbalance valve?

It is a valve designed to control movement in one direction, typically used on hydraulic cylinders.

What is a counterbalance valve Rexroth?

A counterbalance valve Rexrothrefers to high-quality valves manufactured by Bosch Rexroth, widely used in industrial hydraulics.

Can a balancing valve replace a counterbalance valve?

No, they serve different purposes: one controls system pressure, the other controls load.

What is a hydronic balancing valve?

It is used in HVAC systems to regulate water flow and improve energy efficiency.
