Product Specification

Reliable Safety Relief Valve for Bulk Storage Gas Canisters and Transport Tanks with Precision Pressure Management

Product Description:

The reliable safety relief valve is a critical fail-safe pressure management device engineered for bulk storage gas canisters and transport tanks used in large-scale industrial and agricultural operations. This specialized safety valve is not for daily flow control but acts as a guardian, automatically activating to prevent catastrophic tank failure due to over-pressurization. Scenarios such as exposure to fire or a malfunction in the system can cause gas to expand beyond the tank's safe limits. This valve's core mechanism is designed to provide controlled gas release at a predetermined pressure threshold, safely venting excess pressure to protect the integrity of the vessel and the surrounding environment. The valve design incorporates a precision-calibrated spring mechanism that holds a seal in place under normal operating conditions but compresses to open a venting pathway when the internal pressure becomes dangerously high.

Manufacturing these valves requires an uncompromising focus on accuracy and reliability. The core component is a high-tensile spring that is calibrated to exact specifications. The valve body is typically constructed from corrosion-resistant stainless steel to ensure long-term functionality even in harsh outdoor storage conditions. Each valve undergoes a rigorous calibration process where it is tested to open at precisely the set pressure and re-seal once the pressure normalizes. This process is certified and documented for traceability. For companies storing large volumes of propane, ammonia, or other industrial gases, this valve is an indispensable component of their risk management strategy, ensuring compliance with strict safety regulations and protecting both personnel and capital assets from the dangers of over-pressurization.

Bullet Points:

Critical Pressure Management: Functions as an automatic over-pressure protection system for bulk gas containers.

Precision Calibrated Safety Valve: Engineered to activate at a specific, pre-set pressure to prevent tank rupture.

Automatic Resealing Function: Once internal pressure returns to a safe level, the valve automatically closes, preserving the remaining gas.

Rugged Corrosion-Resistant Construction: Made from stainless steel to withstand harsh environmental conditions at storage facilities.

Regulatory Compliance: Designed and tested to meet international standards for pressure relief devices (ASME, PED).

Specific Application Scenario:
A large agricultural cooperative has a bulk propane tank that supplies fuel for crop drying. During a hot summer day, the tank is exposed to direct sunlight, causing the internal pressure to rise. The safety relief valve automatically opens to vent a small amount of vapor, preventing the pressure from reaching a dangerous level, and then reseals once the temperature drops in the evening.

FAQ:

1. At what pressure does this safety relief valve activate?

   • The activation pressure is set based on the design of the storage tank and local regulations. Common settings are 250 PSIG or 375 PSIG for propane tanks. The exact set pressure is clearly stamped on the valve body and provided in its documentation.

2. Is the gas release from this safety valve dangerous?

   • The release is a safety feature to prevent a far more dangerous explosion. The vented gas should be directed away from ignition sources via a vent pipe. The valve is designed to release only enough gas to lower the pressure to a safe level before resealing.

3. How often should this pressure management device be tested or replaced?

   • Industry standards and regulations typically require that safety relief valves be inspected and tested every five years by a certified facility to ensure they haven't become stuck or lost calibration.

4. Can this valve be used for any gas?

   • No. The valve must be compatible with the specific gas service. The materials and calibration are specific to the gas properties (e.g., corrosiveness, density). A valve designed for propane may not be suitable for chlorine, for example.

5. What happens if the valve starts leaking at a pressure below its set point?

   • This indicates a fault, such as a damaged seal or a weakened spring. The valve should be replaced immediately by a qualified technician. A leaking relief valve can lead to a continuous and hazardous gas release.
