Frequently Asked Questions about Soft-Seated Valves and Manifold Blocks
What does “soft seat” mean in valve design?
A soft seat refers to a valve design that uses an elastic sealing material to achieve enhanced tightness and reduced leakage.
Where are soft-seated valves and manifolds used?
They are used in applications requiring high sealing performance, such as pressure measurement and control systems.
What are the advantages of soft-seated valves?
They offer improved tightness, lower operating torque and reliable shut-off.
Which types of soft-seated valves are available?
Available types include isolation valves, gauge valves, multiport valves and manifold blocks with integrated functions.
What is a soft-seated manifold block?
A soft-seated manifold block integrates multiple valves in one body, enabling compact and clearly arranged measurement installations.
Where are soft-seated manifold blocks typically installed?
They are commonly installed in pressure measurement and control systems, either in-line or directly on pressure transmitters.
How do soft-seated valves differ from metal-seated valves?
Soft-seated valves generally provide better sealing performance, while metal-seated valves are more suitable for very high temperatures.
Are soft-seated valves suitable for high pressure?
Yes, many soft-seated valves and manifold blocks are designed for industrial high-pressure applications.
How does the soft seat affect maintenance?
The sealing elements can be replaced if necessary, simplifying maintenance and reducing downtime.
Can multiple valve functions be combined?
Yes, manifold blocks allow several soft-seated valves to be combined in one compact unit.
How does a soft seat influence leakage rates?
The elastic sealing material enables very low leakage rates.
Are different soft seat materials available?
Depending on pressure, temperature and medium, different soft seat materials can be selected.
How do I choose the right soft-seated valve?
Selection depends on pressure rating, process medium, connection type and required valve functions.
