LESER Safety Valves for Industrial Applications API Valve , Boiler Valve , DIN Valve , High Pressure Valve , Industrial Applications , LESER , Oil and Gas Valve , Safety Valve Safety Valves for Industrial Applications API Safety valves according to API 526 with standardized capacities and dimensions High Efficiency Solutions for high plant efficiency Compact Performance Safety valves with compact dimensions and high connection variety High Performance Safety valves for all industrial applications Modulate Action Safety valves for low pressure dynamics Best Availability Additional products for higher plant availability Clean Service Safety valves for food, beverage and pharmaceutical applications Critical Service Safety valves with PTFE-lining for corrosive media S&R Safety valves for heating systems Types of Safety Valves In the context of pressure relief devices, a fundamental distinction can be made between reclosing and non-reclosing devices. Safety valves are part of the reclosing devices and are differentiated on the basis of their loading principle or controllability. In addition, a distinction can be made based on the function of the valves. Here, a distinction is made between relief valves (full lift), normal safety valves and proportional safety relief valves. Notice for mobile users Hold your smartphone horizontally to get the best possible view on the following visualization. There are two main types of safety valves: Spring-loaded safety valves and pilot-operated safety valves. Also relevant are so-called change-over valves, which ensure continuous system availability (not included in the illustration) Sizing of Safety Valves In order to ensure the greatest possible plant safety, the analysis of the conditions and requirements of an application and the corresponding dimensioning of a safety valve is crucial. Determining the necessary dimensions and flow cross-section of a safety valve is referred to as "sizing the safety valve". Numerous parameters are taken into account in this calculation. Examples of relevant substance data: Type and aggregate state of the medium Design standard (DIN, API, AD, ASME) Examples of relevant operating data: Set pressure Operating temperature of the medium Required mass flow (e.g. 10,000 kg/hour) For the sizing of safety valves LESER has developed its own free software VALVESTAR®. You can access the tool via the following link. Safety Valves for Industrial Applications ... Read more »
