Rego Vapor Relief Valves for High-Pressure Regulators

Vapor relief valves are essential components in high-pressure regulator systems used in LPG (Liquefied Petroleum Gas) and anhydrous ammonia (NH3) applications. These valves are designed to safely release excess vapor that builds up in the system due to pressure fluctuations or overpressure conditions, preventing potential damage to equipment or hazards in the operation. Vapor relief valves ensure the safe and efficient operation of high-pressure regulators by maintaining the correct pressure levels within the system and protecting it from overpressure situations.

These valves are typically installed as a safety feature in high-pressure regulator installations to safeguard both the system components and personnel from dangerous overpressures. They are built to respond rapidly to any abnormal pressure rise and act as a fail-safe mechanism to vent excess vapor to a safe area. Vapor relief valves are commonly used in LPG storage tanks, vapor lines, and ammonia tanks to provide a reliable pressure relief solution.

Key Features:

• Overpressure Protection:
  Vapor relief valves are designed to prevent overpressure by automatically venting excess vapor when the pressure exceeds a pre-set threshold, ensuring system integrity and safety.

• Reliable and Safe Operation:
  These valves ensure continuous monitoring and venting of excess pressure, contributing to the safe operation of LPG and NH3 systems, minimizing the risk of accidents or damage.

• Efficient Pressure Regulation:
  By maintaining stable pressure levels in high-pressure regulator systems, vapor relief valves help to ensure that flow rates remain constant and pressure conditions remain optimal for the application.

• Versatility:
  Vapor relief valves are suitable for a wide range of applications, including use in LPG, NH3, natural gas systems, and other high-pressure vapor management systems.

Applications:

• LPG systems for residential, commercial, and industrial use.

• NH3 applications in agricultural and industrial processes.

• High-pressure regulator systems where pressure relief is required to ensure safe vapor management.

Specifications:

• Function:

  • Vapor Relief – automatically releases excess vapor to maintain safe pressure levels in high-pressure regulator systems.

• Pressure Setting:

  • Pre-set to a specific pressure threshold to activate vapor relief when overpressure occurs. Typical settings range from 10 psi to 200 psi, depending on the application.

• Construction Materials:

  • Corrosion-resistant materials such as brass, stainless steel, or carbon steel for durability and long service life in harsh environments.

• Venting Capacity:

  • Designed to handle large volumes of excess vapor, with flow rates varying by model (typically ranging from 1 to 50 SCFM or higher).

• Connection Type:

  • Compatible with standard inlet and outlet sizes typically ranging from 1/2 inch to 2 inches NPT or flanged connections.

• Temperature Range:

  • Operates effectively in a wide temperature range, typically from -40 °C to +65 °C (adjustable based on the specific application and material).

• Safety Features:

  • Includes features such as integrated filters to prevent foreign particles from obstructing valve operation, ensuring reliable performance over time.

• Seal Type:

  • Sealed design to prevent leakage during normal operation and when venting excess vapor.

• Compliance and Standards:

  • Manufactured in compliance with industry standards such as ASME, API, and EN regulations, ensuring reliability, safety, and performance.

Benefits:

• Enhanced Safety: Provides protection from overpressure conditions that could lead to equipment failure or safety incidents.

• Prevents Equipment Damage: Reduces the risk of regulator damage and system degradation by maintaining proper pressure levels.

• Easy Installation and Maintenance: Designed for quick installation and low maintenance, ensuring ease of use and longevity in service.

• Versatile Use: Suitable for various gases, including LPG, NH3, and other high-pressure vapors.
