A flow control valve is used to control and regulate the flow or pressure of fluids. A flow control valve may be used to regulate gas, steam, water and chemicals.

cold chamber die casting machine can be divided into the direction of the direction of the flow of fluid in the hydraulic system used to control or regulate the pressure and flow valves, pressure valves and flow control valve three categories. A same shape as the valve, because of the different mechanisms of action have different functions. Pressure valve and flow valve with a throttle effect of the flow passage cross section to control the system pressure and flow direction valve replacement of the flow passage control the oil flow direction.

this model does not have a heater control valve, it has a specail thermostat that controls flow.

to control the flow of air fuel mixture

reducers are used to improve flow control in a steady nature because when the fluid flow through the pipe there is turbulence in flow. due to turbulence in fluid it effect to measuring devices which vary in readings, to avoid such it need to contract the area of the pipe in shape of reducer is at upstream of the control valve and down stream of the control valve there is expander which helps to fluid to flow in regular size of it.
