What is a hydraulic control valve

The hydraulic control valve produced by Tyco Valve Co., Ltd. is a hydraulic control valve. It consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to different purposes and functions, they can be divided into remote control float valves, pressure reducing valves, slow closing check valves, flow control valves, pressure relief valves, hydraulic electric control valves, etc. Hydraulic control valves are divided into two types: diaphragm type and piston type. The working principle is the same. They are powered by the 4P difference in upper and lower floating pressure. They are controlled by a pilot valve to make the diaphragm piston (diaphragm) hydraulic differential operation. They are completely automatically adjusted by hydraulics, so that The main valve disc is fully open or fully closed or in a regulated state. When the pressure water entering the diaphragm (the control room above the piston) is discharged to the atmosphere or the downstream low-pressure area, the pressure value acting on the bottom of the valve disc and below the diaphragm is greater than the pressure value below, so the main valve disc is forced to completely close position, when the pressure value in the control chamber above the diaphragm piston is between the inlet pressure and the outlet pressure, the main valve disc is in an adjustment state. Its adjustment position depends on the joint control effect of the needle valve and the adjustable pilot valve in the conduit system. .The adjustable pilot valve can open or close its own small valve port through the downstream pressure and changes with it, thereby changing the pressure value in the control chamber above the diaphragm piston) and controlling the main valve disc adjustment position. It is widely used in water treatment projects, water transmission projects, pipe network systems, and industrial water fields.
