  • Ordering Process

The hydraulic control nozzle system consists of main valve, pilot valve, needle valve, ball valve, miniature filter and pressure gauge. When used, the outlet pressure can be maintained automatically when the outlet pressure is adjusted.

This product is self-controlled by guide valve, without other devices and energy, easy to maintain, high accuracy of pressure control, less affected by inlet pressure and flow, and reliable pressure reduction and stabilization.

This series of valve products are widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.

Working principle

When the valve feeds water from the inlet, the water flows through the needle valve into the main valve control room, and the outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the guide valve spring setting value, the pilot valve is closed. When the control room stops draining, the pressure in the main valve control room rises and the main valve is closed, and the outlet pressure is no longer increased.

When the valve outlet pressure drops to the setting pressure of the pilot valve spring, the pilot valve opens and the control room drains downstream. Because the displacement of the pilot valve system is larger than that of the needle valve, the pressure of the main valve control chamber decreases. The inlet pressure opens the main valve. Under steady state, the inlet and drainage of the control room are the same, the opening of the main valve is constant, and the outlet pressure is stable.

The outlet pressure can be set by adjusting the guide valve spring.
