Pressure Reducing Valve

1 Safety: Monitor and adjust the pressure in real time to ensure that the pressure in the system is always maintained within a preset safety range, and effectively prevent equipment damage or personnel injury caused by sudden pressure increases.

2 Economy: By precisely controlling the pressure, unnecessary high-pressure operation is avoided, thereby saving energy costs.In addition, since the pressure reducing valve can prevent equipment damage caused by excessive pressure, it can also reduce the cost of repairing and replacing parts.

3 Energy-saving effect: reducing water pressure can reduce water waste and achieve energy-saving effect.This is particularly important for cities to improve their water systems

4 Extend the service life of the pipeline: reducing the pressure of the pipeline can extend the service life of the pipeline, reduce user troubles and reduce corporate capital and manpower investment.

5 Easy to adjust: the pressure reducing valve has a wide pressure regulating range, and the output pressure can be precisely adjusted as needed to maintain a stable output pressure.

Product Details

hydraulic pressure reducing valve


It controls the flow of liquids and is widely used in aviation, chemical industry, shipbuilding, machining and other fields.Its main function is to achieve precise control of liquid flow, direction, pressure and other parameters.The hydraulic control valve can control and adjust the flow rate, pressure and other parameters of the hydraulic system according to different functional requirements, and can cut off the fluid and change the flow direction.

 

The principle is mainly to change the channel of liquid flow through the movement of the valve core, so as to control the flow rate, pressure and flow direction of the liquid.The position of the valve core determines the flow direction of the fluid and the size of the liquid flow through the valve core channel.Under different working pressures, the hydraulic control valve can adjust the position of the spool to achieve accurate control of liquid flow and pressure.

A valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure.From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of decompression.Then rely on the adjustment of the control and adjustment system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range.

 

The water pressure is reduced by the local resistance of the flow channel in the valve to the water flow, and the range of water pressure drop is automatically adjusted by the film connected to the disc or the inlet and outlet water pressure difference on both sides of the piston.The principle of fixed-ratio decompression is to use the water pressure ratio of the floating piston in the valve body to control, and the pressure reduction ratio at the inlet and outlet ends is inversely proportional to the area ratio of the piston on the inlet and outlet sides.This kind of pressure reducing valve works smoothly and without vibration; there is no spring in the valve body, so there is no consideration of spring corrosion or metal fatigue failure; the sealing performance is good and does not leak, so it reduces both the dynamic pressure (when the water flows) and the static pressure (when the flow rate is 0); especially when the pressure is reduced, it does not affect the water flow.Although the application of water flow through the pressure reducing valve has a large head loss, it is still energy-saving in general because it reduces the waste of water, makes the system flow distribution reasonable, and improves the system layout and working conditions.When the medium is steam, it is advisable to choose a pilot piston type pressure reducing valve or a pilot bellows type pressure reducing valve.For the convenience of operation, adjustment and maintenance, the pressure reducing valve should generally be installed on the horizontal pipe
