The liquefaction process must be designed efficiently so that the LNG can be offered economically. The necessary cryogenic media temperatures of -161 to -164 °C represent a challenge for the technical design of the individual components in the plant. This also applies in particular to the safety valves, which must function reliably as the final protection in the event of overpressure, even at the cryogenic process and Russian ambient temperatures.

LESER valves meet all requirements for use in natural gas liquefaction plants and offer a complete product range. The valves are designed in the low-maintenance “Durable Design” and can be adapted to the plants by various options.

The tightness of the safety valves has been proven under real conditions at media temperatures below -146 °C on LESER’s own cryogenic test bench. The precise helium leak test is based on the DIN EN 13648-1 standard.

The plant efficiency was supported by the use of pilot-operated safety valves (POSV) in the relevant areas. In contrast to spring-loaded safety valves, they are tight until they respond and thus meet the requirement of a higher operating pressure in relation to the response pressure of the plant. Six POSVs now support the efficiency of LIMUM® technology the liquefaction plant.

The LESER POSV for LNG is based on the proven design for LPG applications - Liquefied Petroleum Gas, which has been in use for many years as a standardized solution.

For the LNG low temperature range, LESER has further developed the design modularly so that it can be adapted to the respective project requirements. In the plant in Russia, for example, an evaporator was used and the pilot was thermally decoupled from the main valve to ensure a gaseous media state in the pilot. A temperature-resistant PTFE compound for piston sealing in the main valve enables the spring-loaded lip seal to be used at operating temperatures as low as -162 °C. The main valve is equipped with a PTFE compound for the sealing of the piston. The special seat bushing design does not require a soft seal in the wetted inlet area. The controlling pilot valve is available with a low-temperature resistant soft seal in Pop Action and Modulate Action versions for various requirements.

LPG (Liquefied Petroleum Gas) and NH3 (ammonia) are the goods which might carry risks during transportation and storage. Vapor that occurs during storage and transportations should be controlled carefully. That can be done with special pressure relief valves which are specialized for these gases.

For fully internal, not to affect from the outside damage, all parts of the PRV is embedded into the tank. With this way it is exposed the pressure from inside directly and is not being affected from any outer intervention. When a vehicle is carrying LPG or NH3 and if there occurs any accident, fully internal PRV helps to keep the gas inside. It is mostly used for the transportation purposes.

On the other hand, semi internal pressure relief valves are used mostly for the tanks which store LPG & NH3. Cause of those tanks are fixed and do not have the risks of rolling over, semi internal PRVs are the most suitable solution for them.

However, the safe useful life of the valve may be shortened by certain environmental conditions and other factors. At times, replacement may be necessary much sooner. Routine inspection and maintenance of pressure relief valves ensures the safe operation of your storage tanks.

TransTech Energy maintains specialized equipment to safely flare off your tanks and quickly replace your internal pressure relief valves. We will also replace the relief valves on your Multiport assemblies, allowing you to avoid the potential loss of your entire tank"s contents through mishandling of this procedure.

With the assistance of experienced and dedicated professionals, we offer highly durable range of LPG Safety Relief Valve that are easy to install and are performance oriented.

Safety relief devices remain closed during normal service operation & have been designed to automatically release a certain gas flow out of the pressurized line through the safety relief valve, as soon as the pressure within the section to be protected will have risen to the preset pressure, safety relief valve gets opened.

Although flammability is one of the significant safety concerns with LPG, it is not the only one. Sound safety practices can address the hazards associated with LPG production, storage, and transportation. The safety relief valve is a device that primarily focuses on the protection of life, property and the environment. It is designed to protect the pressurized vessel or system against over-pressure in case all other systems fail.

A safety relief valve is specifically designed to open and relieve the excess pressure from the equipment or vessel and re-close to prevent further release of the gas once normal conditions are restored. It is often the last line of defence for the operation and must be certified and capable of operating at all times under all circumstances.

During the operation of LPG, the safety relief valve is usually closed until the pressure upstream reaches the desired set pressure. Once it reaches the set pressure, the valve cracks open and continues to open further, allowing more flow when the pressure increases. When the upstream pressure falls below the set pressure, the valve will close again. The safety valve has a valve element, a sensing element and a reference force element. One of the most critical quality characteristics of the valve is its functional tightness between the seat and the disc. Since reliability of the device is related to its functionality and performance, the design of the safety relief valve must be as uncomplicated and efficient as possible.

Various types of safety relief valves available for multiple uses like pop action safety valve, tank mounting valves, thermal safety relief valve, angle type safety valve, excess flow check valve

LPG cylinders or tanks should never be liquid-full. Climatic conditions can influence the degree of completeness required. However, it is considered standard practice to fill only 80% of the water capacity of the vessel. In some instances, overfill devices can be required to provide protection.

WITT is a manufacturer of Pressure relief valvesor Safety relief valves for technical gases. They are designed to protect against overpressure by discharging pressurized gases and vapors from pipelines, pressure vessels and plant components. Safety relief valves (SRV) are often the last line of defense against explosion – and such an explosion could be fatal. Other common names for safety relief valves are pressure relief valve (PRV), safety valve, pressure safety valve, overpressure valve, relief valve or blow-off valve.

WITT safety valves are very precise. They are individually preset to open at a predetermined pressure within the range 0.07 to 652 Psi. Their small size and orientation-independent installation allow a wide range of connection options. WITT relief valves also stand out due to their high blow-off flow rates of up to 970m³/h. They can be used within a temperature range of -76° F to +518°F and even with very low pressures.

For maximum safety, WITT undertakes 100 % testing of each safety relief valve before it is delivered. In addition, WITT offers individual testing of eachsafety valveby the TÜV, with their certificate as proof of the correct set pressure.

WITTsafety relief valvesare direct-acting, spring-loaded valves. When the preset opening pressure is reached, a spring-loaded element in the valve gives way and opens, and the pressure is relieved. Once the pressures are equalized, the valve closes automatically and can be reactivated any time the pressure rises again. Depending on the application and the nature of the gas, the safety relief valvescan either discharge to atmosphere, or via a connected blow-off line. The opening pressure of the safety valves is preset by WITT at the factory according to the customer’s requirements.

Safety relief valvesare used in numerous industries and industrial applications where, for example, gases pass through pipelines or where special process vessels have to be filled with gas at a certain pressure.

For most industrial applications using technical gases, brass is usually the standard material of construction of thesafety relief valvebody/housing. For the use of pressure relief valves with aggressive and corrosive gases, the housings are made of high-quality stainless steel (1.4541/AISI 321, 1.4404/AISI 316L, 1.4305/AISI 303 or 1.4571/AISI 316Ti). The use of aluminium as a housing material is also possible.

Depending on the type of gas used and individual customer requirements, various sealing materials and elastomers are available to ensure the safety of your systems under even the most difficult conditions.

WITT pressure relief valves are available with different connections. In addition to the standard versions with the usual internal or external threads, special versions with KF or CF flanges, VCR or UNF threads can also be ordered. Special adapters for connecting the safety relief valve to a blow-off line are also available.

LPG and Industrial valve are devices that control the flow and pressure of liquid and gases within a system. Valves are used to control the flow of liquids and gases in the piping system and it should be checked consistently to avoid any risks such as leakage and corrosion. On the other hand, valves used in industries can be operated manually or automatically.
