Relief Valves
Tips & Advice to help you make your decision on Relief Valves
Relief valves prevent pressurized liquids, gases and plasma from causing catastrophic containment failures by venting some of the pressure into the air or a nearby container. These valves are very important in the natural gas, nuclear and propane industries. Smaller scale examples also include carbon dioxide, or CO2, tanks and fuel for gas-powered lanters. Your small business can gain additional revenue streams through the sale of these key components.
Quality relief valves come in many different forms. Plastics and synthetic materials work well for gasses at low temperatures with little risk of heat exposure. Metal valves protect more hazardous equipment or those that work under high heat and pressure. Relief valves may be operated by a single person or require a complex computerized instruction to complete the venting. The latter systems are often found in sensitive areas such as power generation and military applications. Your company may also find employment as contractors troubleshooting and repairing such systems.
Relief valves can prevent major disasters before they become unmanageable. Many industry standards surround the use and manufacture of such valves. Local and state ordinances may apply, and Business.com remains a great source for the latest information on relief valves and other opportunities for your small business.
Relief Valves
Let off some steam and avoid serious damage with relief valvesBy W. Aiman Mueller Whether your pipe or tube system runs air, steam, gas or liquid, pressure relief valves significantly increase safety for your system and workers. Most pressure relief valves do not restrict flow. When pressures exceed safe levels within a system, the relief valve opens and lets steam, gas or liquid escape. This prevents the system from rupturing or, in some cases, exploding.
The pressure level at which a relief valve will open is often built in, but the alternative is an adjustable relief valve. A coil or hydraulic spring holds a relief valve closed. When pressure levels rise too high, the pressure compresses the spring to open the relief valve. Once pressure falls down to a normal range, the relief valve closes again.
Relief valves are different from other valves, but they are available in several common forms, including:
1. Diaphragm relief valves
2. Globe relief valves
3. Swing check relief valves
