Product Introduction
Pilot operated pressure reducing valve is a direct acting film spring pressure reducing valve, which is designed and manufactured on the basis of absorbing the advantages of similar foreign products. It is mainly composed of diaphragm, settle valve disc, adjusting spring and other parts. Diaphragm sensing downstream pressure changes to drive the valve disc, change and control the valve opening to achieve decompression and pressure regulation function. The outlet pressure is set by setting the spring pressure.
Product Superiority
Pilot operated pressure reducing valve increases the diaphragm area appropriately and improves the sensitivity. Stable and sensitive decompression and pressure stabilization. It is suitable for the branch pipeline of high-rise buildings, apartment buildings and residential areas, as well as the household branch pipe of apartments and residences.
Discharge Coefficient
1. The maximum decompression ratio is as high as 20∶1. The previous two decompression stages can be realized with one stage now.
2. Due to the large diaphragm and the external detection structure, stable secondary lateral pressure can be controlled.
3. Due to the large CV value and the leap improvement of flow and control ability, the products which are 1 ~ 2 numbers smaller than the usual nominal diameter can also be used.
4. Because the valve is single spherical, its sealing ability is improved, the leakage is very small.
5. Can manage low pressure up to 0.02 Mpa.
