Function and Description

Highly Developed Pressure Relief Valve

The SD/BS-H type PROTEGO® valve is a highly developed pressure relief valve Soupape de surpression Valve designed to open and relieve excess pressure and to reclose and prevent the further flow of fluid after normal conditions have been restored. with a heating jacket down to the flange. It is primarily used as pressure relief device Appareil A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. for vessels and process engineering equipment Appareils Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. under difficult operating conditions. This includes extreme weather conditions or products that tend to form polymers at certain temperatures, stick together, or form deposits that negatively influence function (such as bitumen, tar, dust). The valve offers reliable protection against overpressure Surpression Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure. and prevents excessive loss of product Produit Includes equipment, protective systems, devices, components and combinations of these. vapors close to the set pressure Pression de réponse Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. .

Full Lift Technology

The device will start to open as soon as the set pressure is reached and only requires 10% overpressure to full lift Course Lift is the actual travel of the valve pallet from the main valve out of the closed position. . Continuous investments in and a commitment to research and development have allowed PROTEGO® to develop a low pressure valve which has the same opening characteristic as a high pressure safety relief valve. With this “full lift type” technology, the valve can be set at just 10% below the maximum allowable working pressure of the tank and still safely vent the required mass flow.

Advanced Manufacturing Technology

Due to our highly developed manufacturing technology, the tank pressure Pression de la cuve Tank pressure is the pressure within a tank. is maintained up to set pressure with a tightness that is far superior to the conventional standard. This feature is achieved by valve seats made of high-grade stainless steel with precisely lapped valve pallets and a sturdy housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. design.After the excess pressure is released, the valve re-seats and provides a tight seal Joint A seal prevents or limits unwanted transfer of product from one container to another. Seal is used as superordinate term for all types of sealing elements. again.

Flow Capacity Chart

The flow capacity charts have been determined with a calibrated and TÜV certified flow capacity test rig. Volume flow V in (m³/h) and CFH refer to the standard reference conditions of air ISO 6358 (20°C, 1bar). For conversion to other densities and temperatures refer to Sec. 1: “Technical Fundamentals”.
