leser pressure safety valve pricelist

The primary purpose of a safety valve is to protect life, property and the environment. Safety valves are designed to open and release excess pressure from vessels or equipment and then close again.

The function of safety valves differs depending on the load or main type of the valve. The main types of safety valves are spring-loaded, weight-loaded and controlled safety valves.

Regardless of the type or load, safety valves are set to a specific set pressure at which the medium is discharged in a controlled manner, thus preventing overpressure of the equipment. In dependence of several parameters such as the contained medium, the set pressure is individual for each safety application.

4 News High Pressure Pilot Operated Safety Valves LESER has extended the range of its product group High Efficiency with a new Pilot Operated Safety Valve (POSV) for high pressures from 102 to 256 bar / 3,705 psig. Launch of series production is now complete: Pilot operated safety valves for high pressures up to class 1500 / PN 250 will start shipping in February With more than 1800 POSVs sold to date, the Pilot-Operated Safety Valve is already a success story. With this, LESER is one of the few full suppliers of pilot-operated and spring-loaded safety valves according to API 526. An expansion of the pilot operated safety valve operating range for up to 426 bar / 6,710 psig is in progress and market launch is planned for In addition to the higher permissible pressures, LESER also offers a number of innovative product configurations for industry-specific options. The new valve covers outlet flange ratings class 300 x 300 and 600 x 300 which go beyond API 526 but are often required in plants. For high pressures as well as high temperatures, LESER offers a version with a stellited disc. With this method, the sealing surfaces are especially hardened which offers a high functional tightness. Higher tightness requirements at especially low temperatures can be fulfilled with the new sealing plate made of PEEK or PTFE inside the main valve. A full nozzle design is required for industrial processes with corrosive media. LESER is one of the few suppliers offering a high pressure pilot-operated safety valve with a full nozzle with the same leadtimes as the standard semi nozzle version. Another improvement was achieved in making seals more resistant to explosive decompression (ED Design), an important factor in petrochemical and other applications with high pressures. For applications with high back pressures or special requirements for tightness up to set pressure, a pilot-operated safety valve can often be an attractive alternative to spring-loaded safety valves. The flange ratings up to 1500 x 300 and the new option codes R3A and R3B can already be ordered.

8 General News LESER presents application-oriented solutions for FPSOs The harsh offshore environment and specific characteristics of oil and gas as a medium pose challenges to equipment on oil and gas installations. The API product group of flanged safety valves is an ideal fit for applications on board FPSOs. The valves not only meet all the requirements of API 526 such as standardized orifices and center-to-face dimensions, but their robust construction with hardened or stellited discs and stellited seats makes them especially suitable for high pressures. and power generation. The special technical requirements for this type of equipment result from the diverse media and processes on an FPSO as well as the seawater environment in which it operates. Corrosion resistant safety valves required For sea water or seawater hydrocarbon emulsions as a protected medium, valve materials must be especially resistant to corrosion in order to enable longer service intervals and to ensure the operational reliability of the safety valve. LESER pressure relief valves are available in various levels of corrosion resistance which can easily be configured according to individual application in short lead times. With the API Alloy Concept, LESER offers duplex and super-duplex materials as well as nickel-based materials like Monel, Hastelloy and Inconel in configurations for different corrosion protection levels. With regard to sour gas (H 2 S) service, valve materials must comply with the specifications of the National Association of Corrosion Engineers (NACE) MR0175/ ISO With a wet and salty external environment, the outside shell of the valve must also be made from corrosion-resistant materials or be adequately coated. MR0175-compliant valve configurations can be ordered as well as multi-layer and epoxy coatings. ABS and US Coast Guard approval for LESER valves Pilot operated safety valves from the High Efficiency product group are also an ideal fit for FPSO applications because of their smaller size and lower weight than traditional spring-loaded safety valves. Pressure relief or safety valves are used on FPSOs to protect the different topside modules for oil and gas separation and treatment, compression, water injection FPSOs and equipment installed on board require class society approval. LESER s valves have been type approved by ABS and the US Coast Guard as well as a number of additional classification societies. In order to allow for international operation of an FPSO, spare parts and replacement valves must be available around the globe. LESER supports its clients with an international network of local storage to ensure availability with short lead times. 8
