The FISHER 1098 – EGR DN50 regulator is a high – performance pilot – operated high – pressure regulator. Here is its introduction:

Design and Structure: It is designed to meet the engineering requirements of large – capacity and precise control. It adopts a radial – flow design, featuring a small installation space and a large flow capacity. The internal parts are made of all – stainless – steel, which not only ensures a long service life of the regulator, but also enables it to adapt to a variety of different working environments.

Performance Characteristics: It has precise control and tight shut – off. It can be used for monitoring connection with excellent safety performance. Equipped with a large – diaphragm actuator and a pilot, it is sensitive in action and fast in response. The pressure setting is simple. It has a high – performance noise – reduction design, and there are various monitoring methods available. The accuracy can reach ±1%. It can work under extremely low differential pressure (△p≤0.07 bar), and various sizes of actuators can be selected to meet the requirements of different flows and differential pressures.

Pressure and Flow: The maximum inlet pressure can reach 102 bar, and the outlet pressure range is 0.69 – 41.4 bar. For the DN50 regulator, its maximum flow can reach a certain value (although the specific flow for DN50 is not clearly given, the maximum flow of the overall model is 570620 Nm³/h for reference).

Maintenance and Application: It can be maintained online. The structure of the quick – opening valve core combined with the double – pilot, which is optional, is especially suitable for direct – firing equipment. It is applicable to various gases such as natural gas, artificial gas, liquefied petroleum gas, and air.
