Safety Valves

Providing critical protection against the risk of overpressure in process systems, safety valves are fundamental elements of plant safety. These valves open automatically when the set pressure is reached, relieving excess fluid from the system to protect equipment and personnel. ORFA Industrial offers high-performance and reliable safety valves compliant with international standards (API 526, ASME). Our extensive product range provides ideal solutions for different fluid types and operating conditions, enabling businesses to operate continuously and safely. Secure your systems with quality safety valves.

Industrial Safety Valve Solutions

Overpressure situations that can occur in industrial facilities, boilers, pressure vessels, and pipelines pose serious safety risks. Safety valves play a vital role in minimizing these risks and maintaining system integrity. ORFA Industrial offers a broad portfolio of safety valves for critical sectors such as oil and gas, chemical, energy, and food and beverage. Our engineering team provides technical support on correct set pressure, capacity, and material selection based on the specific needs of each project. Manufactured in compliance with international standards (API 526, ASME), these safety valves deliver superior performance even under high temperature, corrosive fluid conditions, and demanding working environments. Maximize your facility's operational continuity and safety with reliable safety valves. These critical safety valves prevent potential damage and production losses by providing fast and effective relief during sudden pressure surges.

Safety Valve Types and Applications

The diversity of industrial applications has created the need for different types of safety valves. ORFA Industrial offers comprehensive solutions with safety valves suitable for all types of process requirements. These critical safety equipment are indispensable for protecting systems from overpressure.

Safety Valves by Connection Type and Operating Principle

  • Threaded Safety Valves: Ideal safety valves for small diameter and low capacity systems.
  • Flanged Safety Valves: Reliable safety valves used in high pressure and large diameter industrial lines.
  • Spring-Loaded Safety Valves: Standard type safety valves operating directly by pressure.
  • Pilot-Operated Safety Valves: Preferred safety valves for applications requiring precise set pressure and high capacity.

Applications

  • Steam boilers and steam lines
  • Compressed air tanks and compressor systems
  • Chemical reactors and storage tanks
  • Oil refineries and gas processing plants

Selecting the Right Safety Valves

Choosing the correct safety valves for a system not only ensures compliance with legal regulations and industrial standards but is also critical for operational safety and efficiency. An incorrectly selected safety valve can lead to system overpressure due to inadequate relief capacity, wrong set pressure, or unsuitable materials, causing severe equipment damage, production downtime, and even loss of life. ORFA Industrial provides the most suitable safety valves solution by considering your project's specific fluid properties, operating temperature, pressure values, and environmental conditions. Our expert team offers technical consultancy at every stage, from set pressure calculations and material selection to installation and commissioning, guaranteeing your system operates with maximum safety. Experience long-lasting and trouble-free operation with high-quality, correctly selected safety valves, thus minimizing risks.

Technical Criteria

  • Set Pressure: The critical pressure value at which the valve opens and its blowdown rate.
  • Relief Capacity: Amount of fluid to be relieved during overpressure (kg/hour or m³/hour).
  • Material Selection: Compatibility with fluid chemical properties, temperature, and corrosion resistance (Stainless Steel, Carbon Steel, Special Alloys, etc.).
  • Connection Type and Nominal Diameter (DN/PN): Flanged (ANSI/DIN) or threaded (NPT/BSP) connection options suitable for the system piping.

Operational Advantages

  • High system safety, equipment, and personnel protection.
  • Extended equipment lifespan and reduced long-term maintenance costs.
  • Full compliance with international standards (API, ASME, ISO) and local regulations.
  • Reliable safety valves ensuring uninterrupted production and increased operational efficiency.

Frequently Asked Questions

What is a safety valve and what does it do?

Safety valves are critical equipment that automatically opens when overpressure occurs in pressurized systems, relieving excess fluid to ensure the safety of the system and personnel. These valves activate upon reaching the designated set pressure.

What is the difference between a safety valve and a relief valve?

Safety valves operate on a rapid opening (pop action) principle to relieve gas or steam, whereas relief valves open proportionally and are typically used for liquids. Both valves prevent overpressure, but their operating principles differ.

How is the safety valve set pressure determined?

The safety valve set pressure is determined based on the maximum allowable working pressure (MAWP) of the equipment being protected. It is typically set at 10% below the MAWP or according to the rates defined by relevant standards (ASME, API). Correct set pressure is vital for system safety.
