1. Product Overview
1.1 Product Description
The 100S Pneumatic Quick Cut-Off Valve is designed for rapid shut-off and reliable isolation of process media in industrial pipeline systems.
The valve combines a pneumatic actuator with a regulating valve body to provide fast operating response. Its structure is suitable for applications requiring dependable cut-off performance and automatic operation.
According to the product specifications, the 100S series covers multiple nominal sizes and pressure classes, allowing it to be selected for different industrial operating conditions.
1.2 Customer Value
The 100S provides customers with an effective way to improve process isolation and reduce reliance on manual valve operation.
Fast pneumatic actuation helps shorten the time required to interrupt process flow. In automated systems, this supports quicker response to operating signals and helps protect process equipment when rapid isolation is required.
2. Product Features
2.1 Fast Pneumatic Operation
The pneumatic actuator provides rapid valve movement, making the 100S suitable for applications where quick opening or closing is required.
2.2 Reliable Cut-Off Performance
The valve is designed to provide dependable shut-off of the process medium. This makes it suitable for pipeline isolation and process cut-off duties.
2.3 Multiple Size Options
The 100S series is available in a range of nominal diameters, allowing customers to select the appropriate valve according to pipeline size and required flow capacity.
2.4 Multiple Pressure Classes
Different pressure ratings are available to meet varying pipeline and process requirements.
2.5 Industrial Material Options
The technical data provides multiple valve-body and internal material options, enabling selection according to the process medium, temperature and operating environment.
3. Working Principle
3.1 Pneumatic Actuation
Compressed air acts on the pneumatic actuator and generates the force required to operate the valve.
3.2 Valve Movement
The actuator converts pneumatic force into linear movement and drives the valve stem and internal closing element.
3.3 Quick Cut-Off
When a cut-off command is received, the actuator rapidly changes the valve position and interrupts the flow through the valve.
This rapid action allows the 100S to perform process isolation more quickly than manual valve operation.
3.4 Automatic Operation
The pneumatic operating mechanism allows the valve to be incorporated into an automated process-control or shut-off arrangement.

The product technical table also provides configuration information covering actuator, valve-body, trim, packing and optional accessories. Final configuration should therefore be selected according to the actual process conditions rather than using one specification for every application.
4.2 Valve Selection
When selecting a 100S valve, customers should provide the main operating conditions, including:
- Pipeline size
- Operating pressure
- Operating temperature
- Process medium
- Required flow capacity
- Required shut-off action
- Valve-body and trim material requirements
- Available pneumatic supply
- Required accessories
This information helps determine the appropriate valve configuration for the application.
5. Structure and Configuration
5.1 Pneumatic Actuator
The upper pneumatic actuator supplies the operating force required for fast valve movement.
5.2 Valve Body
The valve body provides the pressure-containing flow passage and connects the valve to the process pipeline.
5.3 Valve Trim
The internal valve components control the flow passage and perform the final cut-off action.
5.4 Packing and Sealing
The 100S provides packing and sealing options suitable for different process conditions. The technical specifications list PTFE and flexible graphite among the available packing materials.
6. Applications and Customer Benefits
6.1 Industrial Pipeline Isolation
The 100S can be used in industrial pipelines where process media need to be opened or isolated through pneumatic operation.
6.2 Automated Shut-Off Systems
Pneumatic actuation makes the valve suitable for systems where valve operation needs to respond automatically to control signals.
6.3 Faster Process Response
Quick valve action reduces the time between the operating command and actual process isolation.
For customers, this can improve the responsiveness of the overall control or shut-off system.
6.4 Reduced Manual Intervention
Remote pneumatic operation reduces the need for operators to open or close the valve directly at the pipeline.
This is especially useful in automated production systems and locations where frequent manual operation is inconvenient.
6.5 Flexible Configuration
Multiple nominal sizes, pressure classes, materials and configuration options allow the 100S to be adapted to different process requirements rather than limiting customers to a single standard configuration.
