Safety Valve

When selecting and purchasing a safety valve, having technical knowledge and being familiar with reputable brands is highly important. At the specialized Damatajhiz group, you can review technical specifications, check up-to-date prices of various safety valves, and make an accurate comparison between trusted brands.

Comprehensive Guide to Selecting and Buying Safety Valves

A safety valve is one of the most critical protective devices in industrial applications, designed to prevent pressure from exceeding allowable limits in pressurized vessels. By opening automatically, the valve releases excess pressure, preventing equipment damage and potential hazards. In industrial standards, this device is also referred to as a Pressure Safety Valve (PSV).

What Is a Safety Valve?

What is a safety valve in a wall-mounted boiler? A safety valve is a vital component in wall-mounted boilers, designed to prevent excessive pressure buildup in the heating circuit. When system water pressure exceeds the allowable limit (typically around 3 bar), the valve opens automatically and discharges part of the water to restore normal pressure. The safety valve protects the heat exchanger and other boiler components, ensuring safe operation. Regular inspection and ensuring the proper condition of this component are essential for proper boiler maintenance.

As mentioned, safety valves perform a protective function by regulating pressure. When the inlet fluid pressure exceeds a specified value, the valve operates automatically, opening the disc to discharge fluid and reduce pressure to a standard level. Once the pressure drops below the maximum allowable level, the valve closes again. Pressure is measured in Bar or PSI, and safety valves are manufactured according to ASME or API 526 standards.

Applications of safety valves include hot water storage tanks with coils, double-wall boiler room tanks, fuel storage tanks, boilers, piping systems, pressurized vessels, and more.

Types of Safety Valves

Safety valves are generally designed and manufactured in three main types, each suitable for specific operating conditions and pressure levels:

Spring-Loaded Safety Valve

In this design, the spring applies force against the inlet pressure to keep the disc closed. When pressure exceeds a predefined value, the spring compresses, the disc lifts, and the fluid flows through the valve.

Weight-Loaded Safety Valve

This type does not use a spring. As pressure increases, the disc lifts due to the applied force, allowing excess pressure to be released. It is typically used for low-pressure vessels.

Pilot-Operated Safety Valve

This valve consists of two parts: a main valve and a pilot valve. In this model, pressure is regulated by the pilot valve and is used in high-pressure vessels and large valves where a higher safety factor is required.

Technical Specifications of Safety Valves

The primary application of safety valves on pressurized vessels is to protect the system against excessive pressure. These valves are designed in various models to suit different operating conditions.

In some models, the inlet and outlet diameters are equal, while in others, the outlet diameter is larger than the inlet to ensure faster pressure relief.

Key types of industrial safety valves include:

• Bottom-mounted valves
• Surface-mounted valves
• High-pressure valves
• Shut-off valves

Buying a Safety Valve

Now that we are familiar with the applications of safety valves, it becomes clear that purchasing a safety valve is essential for industrial and construction projects. During the purchasing process, selecting high-quality, standard-compliant valves based on project-specific requirements is crucial. Customers should choose products that meet safety and quality expectations.

Safety Valve Price

The price of a safety valve depends on several factors, including application type, valve model, class, pressure rating, body material, and internal mechanism accuracy. Durable materials and precise design enhance system safety and longevity. Choosing a reputable brand, although increasing the purchase cost, ensures reliable and stable performance.
