YQ98001 filter pressure reducing valve is a kind of valve that uses the energy of the medium itself to adjust and control the pipeline pressure intelligent valve. When the valve is supplied with water from the inlet end, the water flows through the needle valve into the main valve control room, and the outlet

Pressure is applied to the pilot valve through the conduit. When the outlet pressure is higher than the set value of the pilot valve spring, the pilot valve closes. The control room stops draining, at this time the pressure in the control room of the main valve rises and the main valve is closed, and the outlet pressure is no longer raised. When the outlet pressure of the valve drops to the set pressure of the pilot valve spring, the pilot valve opens and the control chamber moves downstream.drain. Since the displacement of the pilot valve system is greater than the water intake of the needle valve, the pressure in the control chamber of the main valve drops. import The pressure opens the main valve. In a steady state, the water intake and drainage of the control room are the same, and the opening of the main valve remains unchanged.

The outlet pressure is stable. The outlet pressure does not change due to the change of the inlet pressure, nor does it change due to the change of the outlet flow of the main valve.

The outlet pressure can be maintained at the set value safely and reliably. The valve reduces pressure accurately, performance Stable, safe and reliable, easy installation and adjustment, long service life. It can be used in domestic water supply and fire fighting system and industrial water supply systems.
