Overview

G200X fire pressure reducing valve is a specialized pressure reducing and stabilizing valve designed and manufactured with advanced international hydraulic control technology. It adopts a groove type (clamp) connection, which has the characteristics of fast, easy, safe, and reliable installation. This valve is mainly used in fire water supply systems and other water supply pipelines that require pressure reduction. It can reduce the high inlet pressure to a stable and satisfactory outlet pressure, and automatically adjust when the flow rate changes to maintain a basically constant outlet pressure, thereby ensuring that end devices such as fire sprinklers and alarm valves work normally under the specified pressure, avoiding overpressure damage, and ensuring the safety and reliability of the fire protection system operation. Its compact structure, easy maintenance, and unrestricted installation site make it an indispensable key control equipment in modern fire engineering.

feature

The throttling position of the main water pressure reducing valve is controlled by an adjustable pilot valve operated in conjunction with a needle valve. The pilot valve senses the downstream (outlet) pressure and immediately reacts, repositioning its piston to increase or decrease the outlet pressure with different demands. The change in the throttle position of the pilot valve piston will cause a change in the flow control water, which will alter the pressure above the diaphragm of the main valve, thereby repositioning the diaphragm assembly and throttling of the main valve to maintain the desired preset reduction in outlet pressure.
