What is a Swagelok Relief Valve?
A Relief Valve is designed to protect equipment and tubing systems from overpressure. When system pressure exceeds the set pressure, the valve opens to release excess pressure and automatically reseals once normal conditions return.

Relief Valve FAQs
1. Question: What is a relief valve?
Answer: A relief valve is a safety device that opens at a predetermined pressure to protect equipment and piping from overpressure.
2. Question: How does a relief valve work?
Answer: When system pressure exceeds the set pressure, the valve opens to discharge fluid until pressure drops back to safe levels, then reseats.
3. Question: What’s the difference between a relief valve and a safety valve?
Answer: Relief valve: used for liquid systems, opens proportionally to overpressure. Safety valve: used mainly for gas/vapor, snaps open quickly.
4. Bleed Valve vs. Relief Valve – What Is the Difference?
Answer: A bleed valve is a manually operated valve used to release small amounts of pressure or trapped fluid from a system, typically for maintenance or safety verification. In contrast, a relief valve is an automatic safety device that opens when system pressure exceeds a predetermined set point to protect equipment and piping from overpressure conditions.
