Manifold Blocks for Differential Pressure Gauges by Armaturenfabrik Franz Schneider GmbH + Co. KG
Manifold blocks for differential pressure gauges from the E-Series of Armaturenfabrik Franz Schneider GmbH + Co. KG are designed for safe and reliable installation of differential pressure measuring devices. These valve assemblies combine functions such as isolation, venting and equalization in a compact block suitable for process and instrumentation connections.
Standard configurations include 3-valve blocks (D3 type) and 5-valve blocks (D5 type), typically offered with center-to-center distances of 37 mm or 54 mm. They are engineered for industrial pressure ranges and provide long service life with low torque operation. Options for specialized applications such as oxygen, sour gas or fugitive emission service are also available. :contentReference[oaicite:6]{index=6}
Frequently Asked Questions about Manifold Blocks for Differential Pressure Gauges
What are manifold blocks for differential pressure gauges?
These are multi-valve assemblies used to connect differential pressure gauges to process lines while providing functions such as isolation, venting and equalization.
What are they used for?
They are used to safely isolate and control the flow of pressure to differential pressure measuring instruments, making installation, calibration and maintenance easier.
Which variants are available?
Common variants include 3-valve blocks (D3) and 5-valve blocks (D5), each offering different functional capabilities. :contentReference[oaicite:7]{index=7}
How does a 3-valve manifold work?
A 3-valve manifold typically includes two block valves and a central valve used for equalizing or venting between the high and low sides.
What distinguishes a 5-valve manifold?
A 5-valve manifold adds additional valves for venting or testing, enabling extended functions such as calibrations without removing the instrument. :contentReference[oaicite:8]{index=8}
What center distances are typical?
Standard center-to-center distances for connections are 37 mm or 54 mm to match common differential pressure gauge interfaces. :contentReference[oaicite:9]{index=9}
Are these blocks suitable for high pressures?
Yes, they are designed for industrial pressures and typically rated up to 420 bar (6,092 psi). :contentReference[oaicite:10]{index=10}
Which materials are used?
They are usually made from corrosion-resistant materials such as stainless steel for durability and resistance to harsh environments.
Which connection types are available?
Connection options include swivel nuts or swivel male connectors to facilitate alignment with process and instrument ports. :contentReference[oaicite:11]{index=11}
Can these blocks be adapted for special media?
Yes, configurations are available for oxygen service, sour gas applications and environments with fugitive emissions.
Are they maintenance-friendly?
Their integrated design simplifies access and maintenance without disturbing the main process line.
How do I choose the right manifold block?
Selection depends on instrument type, pressure range, medium and required valve functions.
Can manifold blocks be combined with accessories?
Yes, accessories like mounting brackets, seals or additional valves can be paired as needed.
Where are these manifold blocks typically used?
They are commonly used in process plants, energy installations and industrial systems where accurate differential pressure measurement is required.
