Juhan Valve's PDV27 / 28 self-operating pressure differential balancing valve is an automatic constant differential pressure balancing valve. It is used to constantly control the pressure difference between the valve or the end equipment supply and return water. Its hydraulic interference. When used with a static balancing valve, flow measurement is possible.
Self-operated pressure difference control, without external power source, relying on its own high and low pressure air chamber pressure changes, changing valve opening, constant end pressure difference; large range of controllable pressure difference; adjustable pressure difference value on site; with shutdown function, through The handwheel is shut off; the inlet and outlet of the valve have a pressure measurement port; a high-pressure air chamber exhaust port;
Dynamic balance is to keep the system balanced by using the pressure change of the control system during the change of the load of the variable flow system from 0% to 100%. The variable flow system can save energy, improve system efficiency, greatly improve comfort and improve control accuracy under dynamic balance. The self-operated differential pressure balancing valve is used for dynamic hydraulic balancing of heating and air conditioning systems, which can reduce the complicated and time-consuming adjustment process.
● Flow control: The self-operated differential pressure balancing valve is connected with an adjustable valve at the end, which can be used for flow control function. The flow control can prevent water shortage at the end of the system, improve the working efficiency of the pump and save energy.
● Noise reduction: The self-operated pressure difference balancing valve can maintain the pressure difference between the inlet and outlet ends of the control valve, which can prevent the control valve from making too much pressure difference between the inlet and outlet ends during part of the load, making noise.
● Easier hydraulic balance adjustment: the self-operated differential pressure balancing valve is matched with each pipe network, and can be set as an independent, non-interactive waterway system module to control the flow of each system module. You only need to adjust the set balance once. Yes, it simplifies the process of hydraulic balance, improves the accuracy of differential pressure control, and greatly reduces the cost and time of hydraulic balance adjustment.
● Regional balance: The self-operated differential pressure balancing valve can set each pipe network system as an independent regional module. The various regional modules are converging to the main system. When the system is expanded or the design is changed, there is no need to readjust the hydraulic balance.
● Constant control valve differential pressure: The self-operated differential pressure balance valve is matched with the control valve, which can constantly control the pressure difference between the inlet and outlet ends of the valve, and increase the power of the control valve to make the control valve more accurate and stable.
