Safety Valves for Compressed Air Systems

Safety valves play a vital role in compressed air systems by releasing excess pressure when system limits are exceeded. This helps protect equipment from damage and reduces the risk of injury to operators, ensuring safe and reliable operation.

Compressed air systems operate at high pressures to power tools, machinery, and industrial equipment. If pressure rises beyond the system’s designed limits, it can place excessive strain on components and create potentially hazardous conditions. Safety valves act as a fail-safe, automatically relieving pressure before damage or failure occurs.

Safety valves are designed to operate automatically and require no manual input. When system pressure exceeds a pre-set limit, the valve opens to allow air to escape, reducing pressure to a safe level before resealing once normal conditions are restored.

Types of Safety Valves Available

• Spring-Loaded Safety Valves – The most common type, using a calibrated spring to keep the valve closed until the set pressure is exceeded.
• Pilot-Operated Safety Valves – Designed for applications requiring rapid release of large volumes of air, using a pilot valve to control the main valve.

Selecting the correct safety valve is essential for effective pressure protection. Key factors to consider include maximum system pressure, air flow rate, and operating temperature. Choosing the right valve ensures compliance, system longevity, and dependable performance.
