Speciality Valve is recognized as the most trusted name among Safety Relief Valve Manufacturers In India. We are known for delivering strong and precision engineered valve that prioritize system protection and compliance. A safety relief valve plays a crucial role in any pressurized system by automatically cutting down excess pressure and ensuring safe operation and minimizing risk.
Components of safety relief valve
- Valve Body: Encases internal components and handles system pressure.
- Spring Assembly: Determines the pressure setpoint for activation.
- Disc or Piston: Opens under excessive pressure to allow fluid discharge.
- Nozzle: Directs the escaping fluid efficiently.
- Adjusting Screw: Enables pressure calibration.
- Bonnet: Protects and supports the internal mechanisms.
Working Mechanism
In a normal state, the valve remains closed as the spring holds the disc against the seat. When pressure builds beyond the designated safety threshold, the force overcomes the spring tension, lifting the disc or piston to vent the excess. As soon as pressure returns to a safe range, the valve resets itself, ready for the next cycle. This automatic behavior ensures uninterrupted protection without manual intervention.
Maintenance and Inspection Guidelines
To ensure long-term reliability, safety relief valves should undergo regular inspection and maintenance. Periodic checks include verifying set pressure, inspecting the spring condition, cleaning the valve seat, and ensuring there is no leakage or corrosion. Our valves are designed for easy servicing, which minimizes downtime during scheduled maintenance.
Speciality Valve also offers customization options like tamper-proof adjustments, soft seats for tight shut-off, and accessories such as pressure gauges or lifting levers depending on operational needs.
Advantages of using safety relief valve
- Promotes Safety: Reduces the risk of overpressure-related failures.
- Hands-Free Operation: Self-activating under critical conditions.
- Accurate Control: Opens only at the defined set pressure
- Built to Last: Withstand high pressure and corrosive environment.
- Standards Compliance: Meet industrial safety norms.

Selecting the Right Safety Relief Valve for Your Application
Choosing the correct safety relief valve is critical to the efficiency and safety of your system. Key factors such as pressure range, temperature conditions, type of fluid (gas, steam, or liquid), and end connections must be evaluated carefully. Material compatibility also plays a vital role. For example, industries handling corrosive chemicals often prefer stainless steel grades like SS316 or CF8M for better resistance. Meanwhile, cast iron and ductile iron are preferred in less aggressive environments due to their cost-effectiveness and durability.
Proper sizing is equally essential. An undersized valve might fail to release pressure effectively, while an oversized valve can lead to premature opening or system instability. At Speciality Valve, we provide expert assistance in sizing and selection to match your exact operating conditions, helping you avoid costly shutdowns or damage.

Importance of Safety Relief Valves in Industrial Systems
Safety relief valves are indispensable in systems where pressure build-up can lead to catastrophic failure. These valves not only protect equipment and pipelines but also safeguard workers and the environment. Regular inspection and maintenance are crucial to ensure optimal valve performance and compliance with safety regulations. Selecting the right material, size, and pressure rating based on the application ensures longer service life and minimal downtime. With advancements in design, modern safety relief valves now offer higher accuracy, quick response time, and adaptability across industries handling steam, gas, liquid, or hazardous media.
