800X Differential Pressure Bypass Balancing Valve Water Conservancy Valve

Introduction

In case of fire, fire fighting is in urgent need of a large amount of water, and domestic water shall be cut off immediately to ensure sufficient fire water; When the pressure of fire water is reduced, the valve will automatically open and be normally open to restore domestic water supply. The valve makes it unnecessary for the system to set up a separate fire water supply network, which greatly saves the construction cost and water consumption. The valve has the advantages of high control sensitivity, safety and reliability, simple commissioning and long service life.

Hydraulic control valve is the valve controlled by water pressure. The hydraulic control valve is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes, functions and places, it can be developed into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc.

A filter shall be installed in front of the 800X differential pressure bypass balance valve and shall be convenient for blowdown.

The hydraulic control valve is a water self-lubricating valve body without additional oil lubrication. If the parts in the main valve are damaged, please disassemble according to the following instructions.

However, there are still some misunderstandings in the application of hydraulic control valve in engineering, such as the applicable conditions of valve, the design and selection requirements of valve, installation points, etc.

Usage:

The valve is used to balance the pressure difference between the supply and return water of the air conditioning system. The valve can improve theutilization rate of the system, maintain the precise and constant value of the differential pressure, and minimize the noise and the damage caused by excessivepressure difference to the equipment
