What is a proportional valve? The so-called proportional valve is a kind of according to the input signal continuously and proportionally control the hydraulic system pressure and flow valve. Control valves commonly used in hydraulic systems are often of a switch-controlled nature. Their function is to allow a hydraulic element to be connected to or disconnected from the hydraulic system, or to perform simple oil circuit switching, etc., without continuous control. Servo valves must be used if the hydraulic system's parameters are to be continuously controlled, but servo valves are expensive. The proportional valve hydraulic system parameters can be continuous and proportional control. Compared with the servo valve, it has the advantages of simple structure, low cost and good universality. Proportional valve in the composition of the ordinary pressure valve, flow valve and the control valve into the proportion of the proportion of electromagnet, with the proportional solenoid to change the suction valve parameters for proportional control.

A fire Extinguishing Agent is a substance that can effectively destroy combustion conditions
and terminate combustion. According to its own state characteristics, it usually can be divided into three categories: liquid extinguishing agent, solid extinguishing agent and gas extinguishing agent
The classification of fire extinguishing agent:
The foam fire extinguishing agent
The carbon dioxide fire extinguishing agent
The 1211 fire extinguishing agent
The dry chemical extinguishing agent: BC powder 1, 2, 3 ABCD powder, D powder
