2.Feature

ZYC self-reliance type differential pressure control valve is a kind of self control USES the pressure of medium changes and keep unchanged through the control system in the medium pressure difference of energy-saving products. Applicable to the heating mode adopts double pipe system of differential pressure control, to ensure that the system pressure difference basically remain unchanged, reduce noise and balance the resistance, eliminating heat supply network hydraulic disorder.

Q:What is the KVS in the valve parameter?
KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
Q:What is a heavy body valve?
Heavy body valves are heavy duty valves. This is the size of the valve, weight, wall thickness are linked, in general, the gate valve and cut-off valve is divided into heavy, medium and light three, other valves are not so distinguished.
Q:What does the valve specification "3/4CL150" mean?
Size: DN20 pressure rating: 150 pounds American Standard
Q:How big valves are used in a DN159 pipe?
DN159 is the valve with the DN150 in the outer diameter of the pipe.
Q:What does the RF of the valve mean?
The flange flange can be applied to the HG/T flange standard, or any other flange standard. HG/T will be more detailed
Q:What's the valve specification DN20?
You should be asking, how many inches?DN20 is 3/4
Q:Valve should be strictly marked according to the direction of instructions and media flow direction to determine the installation direction,
Refers to the installation of the interface dislocation, misalignment or installation of the wrong size and forced connection, resulting in installation stress exists, in use, it is prone to abnormal damage.
Q:Ask about the valve of home improvement
Common valve position is few, 1 or 2 wash basin faucet pipe toilet pool 3 4 water heater 5 water washing machineThese positions require only simple ball valves or globe valves. Gas valves need not be considered, provided by gas installation companies (specific standards).The main valve can achieve the above water source control, the installation of the branch valve is to take into account the maintenance is convenient, does not affect other water.
Q:What is the flow medium of the valve?
Valve flow medium refers to the valve through the fluid, gas and liquid.For example: water, air, oil, gas, steam, acid, alkali, gas, heat conduction oil and so on, are called medium.
Q:The water pipe in the house is broken.
Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!
