25PPilot thin film steam pressure reducing valveOverview:

This series of pressure reducing valves is a new type of pilot operated super large diaphragm pressure reducing valve developed by our company with reference to * products. This product has made significant improvements on the basis of ordinary pressure reducing valves The diaphragm adopts a new material and greatly increases the working area, so even slight changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure. Another prominent feature of this product is that multiple pilot valves can be installed and interchanged on the same valve body to achieve temperature control, upstream pressure control, remote switch control, etc. while stabilizing the pressure.

Pilot thin film steam pressure reducing valveMain technical parameters:

Pilot thin film steam pressure reducing valveMain component materials:

1.The maximum decompression ratio is as high as 20:1, and the previous two stages of decompression can now be achieved with just one stage.
Due to the large diaphragm and the use of an external detection structure, stable secondary pressure can be controlled.
3. Due to the high Cv value and the significant improvement in flow and control capabilities, products with a nominal diameter 1-2 numbers smaller than usual can also be used.
4. Due to the single spherical shape of the valve, its sealing performance is improved and the leakage is minimal.
5. Can manage low pressure below 0.02Mpa.

Valve body: cast steel/stainless steel Valve internals: stainless steel Diaphragm: Stainless steel.
*Method for detecting secondary side pressure:
Generally, external testing methods are used, and products with internal testing methods of other specifications are also produced, but their Cv values are smaller.
*The maximum pressure reduction ratio is 20:1.
*Secondary side adjustment pressure: 85% or less of the primary side pressure (gauge pressure).
*Zui small pressure difference: 0.05 Mpa (0.5kgf/cm2).
*Valve seat leakage: less than 0.01% of rated flow.
