Function and Description

Full Lift Technology

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. This “Full Lift Type” technology allows the valve to be set at just 10% below the maximum allowable working pressure (MAWP) 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 the set pressure with a tightness that is far superior to the conventional standard. This feature is achieved by special valve seats made of high quality synthetic material or PTFE. 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. . The optimized fluid dynamic design of the valve body and valve pallet Clapet Valve pallet is the generic term for the assembly that rests on the valve seat. is a result of many years of research, resulting in a stable operation of the valve pallet, optimized performance, and reduced product losses.

Dimensions

To select the nominal size Diamètre nominal The nominal size is an alphanumeric designation of size for components in a piping system, used for reference purposes, comprising the letters DN followed by a dimensionless integer that is indirectly related to the physical size of the bore or outside diameter of the connections, expessed in millimeters. (DN), use the flow capacity chart on the following page

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”.
