SSBV Series Special Ball Valves: Redefining safety during maintenance work

SSBV ball valves enable safe pressure relief in hydraulic systems prior to maintenance work by combining shut-off and venting in a single component, thereby reliably removing any residual energy from the system.

Trapped energy poses a significant risk, particularly in hydraulic systems. Even after the system has been switched off, pressure and fluids may remain in pipes or components and be released uncontrollably when opened. This is precisely where the System Service Bleed Valves (SSBV) come into play: they ensure that the relevant section of the system is depressurised in a targeted and controlled manner prior to servicing.

In doing so, they play a crucial role in making maintenance operations safer, more predictable and more efficient.

The core function of the SSBV series ball valves is based on the principle of an integrated bleed valve. This enables residual pressure in the system to be relieved in a targeted and controlled manner before a section of pipework is opened.

In hydraulic systems, residual pressure often remains after the system has been shut down and must be actively removed. Bleed valves provide a defined relief opening through which trapped fluids or gases can escape safely.

The SSBV variant combines this function directly with a shut-off valve. This means:

• The flow is first interrupted

• The isolated section is then vented in a controlled manner

This combination not only reduces the need for additional components but also minimises potential leak points and sources of error.

A key safety feature of the SSBV series is the design-determined operating sequence. It ensures that shutting off and venting cannot be carried out independently of one another or in the wrong order.

In practical terms, this means:
The valve mechanism forces the operator to first safely stop the flow of the medium and then relieve the system pressure. Incorrect operation – such as opening a pressurised pipe – is prevented by the design.

Particularly in complex systems or when under time pressure, this intuitive, fail-safe operating logic significantly reduces the risk of human error. Safety is thus not merely dependent on the operator’s qualifications, but is actively integrated into the design.

In addition to its safety features, the SSBV series impresses with its robust and practical design.

Key features include:

• Compact block design for space-saving integration

• In-line mounting for easy system integration

• High-quality materials for high durability

• Pressure resistance up to 420 bar

These features make the valves a reliable solution for demanding industrial applications where high system pressures and robust components are required.

Furthermore, the compact design reduces installation effort and enables clear and straightforward integration into existing systems.

SSBV series ball valves are used in particular in safety-critical applications where an uncontrolled release of pressure or media can have serious consequences.

Typical areas of application include:

• Steelworks

• Heavy industry

• Systems with high system pressures

• Applications with heightened safety requirements

In such environments, faulty shut-off or inadequate pressure relief can lead to significant risks to people, machinery and the environment. The SSBV series specifically counteracts these risks and ensures that maintenance work can be carried out in a controlled and safe manner.
