Product informationA proven all-round valve with proportional operating characteristics and an extremely compact design.In addition to the basic version, these valves are also available for the most varied customer requirements as a gastight version or with lifting lever. The various sealing materials available mean that this valve is suitable for a wide range of media and temperatures.As a closed, gastight version without lifting mechanism it is suitable for all media. This makes this series an economcially interesting alternative for plants which do not require any approval or which do not fall under the PED.In addition, due to its relatively large setting range per spring, it is ideally suited in cases where either a stock valve for various applications and set pressures is required or if the customer is looking for an adjustable pressure relief valve.connection types Internal pipe threadMore information please go link: 628

Product informationThis angle-type pressure relief valve with double lever and weights offers precise protection against overpressure in the case of low set pressures.This is a versatile alternative if the system to be protected does not fall under PED and a compact version is not necessary.The set pressure can be very easily adjusted by the user.connection types Internal pipe threadMore information please go link: 612

Product informationTThis angle-type pressure relief valve with lever and weight is an ideal alternative when in the case of low capacities a TÜV Type Tested safety valve is not necessary.The set pressure can very easily be adjusted by the user.Provided the valve is used correctly, then its simple and robust design guarantee a high degree of reliability.connection types Internal pipe threadMore information please go link: 601

Product informationThe strainers of the 2143 series consist of a straight-through housing made of high-quality stainless steel and, in the case of the 2183 series, of lead-reduced gunmetal. The strainer unit is integrated between the housing and the cover and can be designed with different mesh sizes. The installation of the strainer prevents contamination in the medium and in the downstream process. connection types Internal pipe threadButt weldsSocket weldMore information please go link: 2143
