YSA416 pressure reducing and stabilizing valve
Product Details
YSA416 adjustable pressure reducing and stabilizing valve suitable for fire protection
Pressure reducing and stabilizing valves and adjustable pressure reducing and stabilizing valves are more suitable for firefighting YSA416. The pressure reducing and stabilizing valve adjusts the required pressure through a pilot valve and controls the flow rate of the main valve to achieve pressure reduction. Phone {Puhui Card}! When the pressure behind the valve is lower than the set value, the pressure reducing and stabilizing valve immediately releases the pressure in the main valve control chamber, causing the valve disc to open moderately.
Working principle of YSA416 adjustable pressure reducing and stabilizing valve
YSA416 pressure reducing and stabilizing valve, also known as 200X pilot operated pressure reducing valve, is a fire specific pressure reducing and stabilizing valve that controls the flow rate of the main valve by regulating the required pressure through a pilot valve. When the pressure behind the valve is lower than the set value, the pilot valve immediately releases the pressure in the main valve control chamber, causing the valve disc to open moderately. When the pressure behind the valve reaches the set value, the pressure in the main valve control chamber increases, causing the valve disc opening to decrease until it closes. YSA416 pressure reducing and stabilizing valve can set the pressure behind the valve according to on-site needs, and the pressure behind the valve will not change due to changes in the pressure before the valve, nor will it change due to changes in the flow rate behind the valve.

The supply range of Puhui brand adjustable pressure reducing and stabilizing valve is from the smallest diameter of DN40 to the largest diameter of DN600. There are various calibers in the middle; There are three pressure levels: 1.0MPa, 1.6MPa, and 2.5MPa; The main materials are gray iron HT200 and ductile iron QT450, and the accessories are made of brass material. The pressure regulation range is 0.2MPa to 1.6MPa. Standard wooden crate packaging is used for shipment; The appearance color is usually blue, but special customized colors can also be used; Usually, pressure gauges are not included in the shipment. If there is a need for special instructions.

Installation and commissioning of adjustable pressure reducing and stabilizing valve:
Please refer to the Y series adjustable pressure reducing valve for the installation and commissioning of YSA416 fire specific pressure reducing and stabilizing valveY416 pressure reducing and stabilizing valveRequirements and the following:
1. It is recommended to install exhaust valves in the pipeline system to ensure stable operation of the pressure reducing valve;
2. During installation, attention should be paid to the direction indicated by the arrow on the valve body. For the convenience of maintenance, a certain space should be left around the pressure reducing valve.
2. During installation, attention should be paid to the direction indicated by the arrow on the valve body. For the convenience of maintenance, a certain space should be left around the pressure reducing valve.
3. The import and export pressure should not be less than 0.2Mpa. If it is less than 0.2Mpa, the pressure stabilization performance will deteriorate (the outlet pressure error will increase).
