AS-Schneider Gauge Cocks are basically designed, manufactured and tested according to DIN 16261, DIN 16262 and DIN 16263. According to above standards the cocks are applicable for a max. allowable (Working) Pressure (PS) of 6 – 16 bar (87 - 232 psi) and a max. allowable Temperature (TS) of 50°C (122°F) for liquids, gas or vapors. Originally the AS-Schneider Gauge Cocks were designed for a max. allowable (Working) Pressure (PS) of 25 bar (363 psi) for the G 1/2 models. We kept this pressure class for this kind of gauge cocks, see below Ordering Information. Operating Positions are marked on top of the plug (see also further comments under General Information).

Gauge Cocks by Armaturenfabrik Franz Schneider GmbH + Co. KG
Gauge cocks from Armaturenfabrik Franz Schneider GmbH + Co. KG are specialized valves installed at the connection between the pressure line and a pressure measuring instrument such as a gauge, pressure transmitter or differential pressure instrument. They allow the measurement point to be securely isolated, shut off, or dampened, protecting the instrument from pressure spikes and facilitating maintenance and device exchange.
Gauge cocks are mounted directly ahead of the instrument and enable precise control of the measuring point. They are available in various designs, connection types and materials to meet diverse industrial process requirements.
Frequently Asked Questions about Gauge Cocks
What is a gauge cock?
A gauge cock is an isolation valve placed between a pressure line and a gauge or pressure instrument that allows controlled opening and closing of the measurement connection.
What are gauge cocks used for?
They are used to isolate the instrument from process pressure, protect it from pressure surges, and provide a means to shut off the measurement point for maintenance or device change.
What are the benefits of using a gauge cock?
Gauge cocks provide secure isolation, simple operation and enhanced protection for pressure instruments.
How are gauge cocks installed?
They are typically installed directly in the instrument line before the measuring device, with connection types matching the process and instrument interfaces.
What connection types are common?
Common connections include threaded interfaces, fittings and flange types compatible with the instrument or process line.
Are gauge cocks suitable for high pressures?
Depending on the model, they are suitable for a wide range of industrial pressures encountered in instrumentation applications.
Which materials are used?
Materials such as stainless steel, steel and brass are commonly used to provide strength, corrosion resistance and durability.
How do gauge cocks contribute to safety?
By isolating the measurement point, they improve safety during maintenance, calibration or device replacement without shutting down the entire process.
Can gauge cocks handle aggressive media?
Depending on the material and seals selected, they can be used with aggressive gaseous or liquid media.
What does a damping function mean?
Some gauge cocks include features that dampen pressure fluctuations, protecting the instrument and enhancing measurement stability.
How are gauge cocks operated?
They are usually operated manually using a handle or knob to open or close the connection to the instrument.
Can gauge cocks be retrofitted?
Yes, they can be added to existing gauge connections if the connection type and installation space allow.
How does a gauge cock affect measurement accuracy?
When properly selected and installed, gauge cocks do not adversely affect measurement accuracy and support reliable readings.
Why is the correct seal important?
The right sealing solution is essential to ensure tightness and long service life, especially under pressure or with aggressive media.
How do gauge cocks support maintenance?
They permit depressurizing the measuring point locally, facilitating service and reducing downtime.
How are gauge cocks different from general isolation valves?
Gauge cocks are optimized for instrument connections, while general isolation valves are designed for broader process line isolation.
Why is selecting the right gauge cock important?
Choosing the correct gauge cock ensures compatibility with the instrument, pressure range, medium and installation environment, enhancing reliability and safety.
