Product Description
KEY FEATURES:
Slow closing to prevent water-hammer
Independently adjustable opening and closing speed controls
WORKING PRINCIPAL:
1.The valve is slow-closing valve, the opening and closing speed can be adjusted by the needle valve, reducing the pipe network pressure fluctuations and the impact on the equipment. If the downstream pressure is greater than or equal to the upstream pressure, the main valve closes under the action of the downstream pressure or spring, the closing speed can be adjusted by the opening degree of the needle valve.
2.When the pump is turned off, the downstream pressure is rapidly increased, the pressure on the main valve film increases, main valve close down the system gradually and finally the main valve slowly closed. The closing speed is controlled by the opening degree of the flow rate adjusting valve.
3.When the pump opens, the upstream pressure is rapidly increased, leading to the upper pressure of the main valve film is less than the lower pressure, main valve close down the system gradually and finally the main valve slowly opens. The opening speed is controlled by the opening degree of the flow rate adjusting valve.
