Downstream Pressure Regulators RE Series Pilot Operated Steam designed to regulate the pressure behind the valve and maintain it at a given level. The CV must provide a stable secondary pressure and at the same time provide the required steam capacity. Thus, the RK automatically adjusts the steam flow according to the needs of the equipment.
pilot valve regulates the opening of the main valve in such a way as to ensure constant pressure at the exit, independence from pressure changes at the valve inlet.
Series pressure reducing valves RE companies MIYAWAKI (Japan) are only for pair.
The company produces the following models pilot operated: RE3 and RE10N.
The pilot operated pressure reducing valve consists of four main components: the valve train, the pilot valve, the control piston with guide, and the impulse channel.
Piloted pressure reducing valves (PRVs) for steam are designed to control the pressure downstream of the valve and maintain it at a predetermined level. The valve must provide a stable secondary pressure and the required steam capacity. As a result, the RV automatically adjusts the steam flow according to the needs of the equipment.
The pilot valve controls the opening of the main valve in such a way as to ensure a constant outlet pressure, regardless of changes in inlet pressure. MIYAWAKI (Japan) RE series pressure reducing valves are designed for steam only. The company produces the following models with pilot control: RE3 and RE10N. This type of valve consists of four main components: a valve train, a pilot valve, a control piston with a guide, and an impulse channel.
Let us consider in more detail the pressure regulators after ourselves, presented on the website of the Artesia company. RE10N is a flanged control valve with a body made of FCD450 ductile iron. It is integrated into pipelines with a diameter of 15-50 mm, the maximum pressure in which does not exceed 16 atmospheres. Structurally, this valve can be equipped with three types of flanges: JIS, ASME, DIN. Depending on the diameter of the flow section, the products weigh from 7 to 15.5 kg. The length of the taps varies between 160-220 mm, and the height is 213 mm (for Dn 15-25) and 257 mm (for Dn 32-50).
RE10N steam pressure reducing valves and other pilot operated models are manufactured by the Japanese concern MIYAWAKI. The products of this brand are of high quality, reliability, wear resistance and prolonged service life.
Regulating valve RE10N - technical data:
The RE3 direct acting regulator is also suitable for pipelines DN 15-50 mm with a maximum system pressure of 16 atmospheres. However, this fitting is made of C3771 brass and is equipped with an Rc or NPT threaded coupling instead of flanges. Compared to RE10N, these products are lighter, their weight varies in the range of 2.8-8.2 kg. The overall parameters of the valves are as follows: length 90-140 mm, width 74-110 mm, height 145-200 mm.
Safety valve RE3 - technical properties:
The above models, thanks to pilot control, are able to maintain high performance and better accuracy compared to conventional direct acting valves. Thus, the stability of the system operation and the efficiency of transporting water vapor through the pipeline are increased. Note also that the flow is adjusted automatically based on the current needs of the equipment. As a result, the working medium is correctly consumed, and the pressure is maintained at a given level.
