SAMSON Safety Instrumented Systems
When it matters: protection at the highest level
For safety-critical processes, SAMSON offers intelligent Safety Instrumented Systems (SIL 2 and SIL 3 according to IEC 61508/IEC 61511) to ensure reliable, standards-compliant, and cost-effective operation – even under extreme conditions.
Our single-channel (SIL 2) and dual-channel (SIL 3) systems consist of perfectly matched valves, controllers, and sensors. Proof of the achieved safety level, including PFD values, is documented by a manufacturer’s declaration.
Emergency Shutdown – When Every Second Counts
Sometimes a single moment decides over safety and stability. Amid pressure, heat, and motion, it silently keeps watch in the background: the emergency shutdown.
It intervenes when all other systems fail – fast, automatic, uncompromising. Whether in case of overpressure, excessive temperature, or power failure: the emergency shutdown isolates, blocks, and protects. It is the last shield of your plant – and the first guarantor of safety.
The emergency shutdown is often part of a Safety Instrumented System (SIS) and subject to a SIL (Safety Integrity Level) rating to ensure it operates reliably in an emergency.
Check Valve – The Silent Hero of Your Plant
In every plant, a medium – water, steam, gas – flows purposefully through pipes and valves. But what happens when it suddenly starts flowing back?
That’s where it comes into play: the check valve. Invisible yet indispensable, it protects your processes from contamination, pressure damage, and system failures. It immediately detects when something is moving in the wrong direction – and reliably shuts off.
What Advantages Do SAMSON Safety Instrumented Systems Offer?
- Certified safety
Our control valves, regulators, and automation solutions are designed according to IEC 61508/61511 for SIL 2 and SIL 3 to ensure maximum operational safety.
- Seamless integration into your safety concept
SAMSON products can be easily integrated into existing safety concepts (e.g., based on your HAZOP analysis) – for a consistent safety architecture from sensors to actuators.
- High availability with maximum safety
Our safety components not only provide protection in the event of a fault but also ensure high plant availability during normal operation – thanks to robust design, precise control, and long service life.
- Reliable stand-alone solution
Thanks to thoughtful design and high manufacturing quality, our SIL-compliant systems are particularly reliable – ideal for use in complex process environments without requiring a safety PLC.
- Engineering support & documentation from a single source
SAMSON provides comprehensive technical documentation, safety proofs, and consultancy for the design of your safety-related control loops.
- Maintenance concept
Simple and reliable maintenance thanks to SAMSON’s maintenance concept for Safety Instrumented Systems. Benefit from our experience!
The single-channel check valve consists of a control valve and a differential pressure gauge, and monitors the flow through the valve assembly using a differential pressure transmitter. If a defined limit is undershot, backflow against the flow direction can no longer be excluded. The single-channel check valve safely shuts off the pipeline in a safety-related manner.
The dual-channel check valve consists of a shut-off and a control valve and two differential pressure gauges, and monitors the flow through the valve assembly using a differential pressure transmitter. If a defined limit is undershot, backflow against the flow direction can no longer be excluded. The dual-channel check valve safely shuts off the pipeline in a safety-related manner.
