Dynamic Flow Control Valve Performance and characteristics of self-operated flow control valve 1.The flow can be set according to the design or actual requirements, which can automatically eliminate the pressure fluctuation of the system and keep the flow unchanged. 2.Overcome the uneven heating and cooling of the system and improve the quality of heating (cooling). 3.Thoroughly resolve the contradiction between large proximal pressure difference and small distal pressure difference. 4. Reduce the amount of water circulating in the system and reduce system resistance. 5. Reduce the design workload, without the need for tedious hydraulic balance calculations on the pipe network. 6.The layout of the pipeline network is simple, and it is not necessary to use the same layout method to reduce the cost of the pipeline network and the maintenance costs. 7.Reduce the difficulty of network adjustment and change the complicated network adjustment work into simple traffic distr...

Static Balance Valve SPF type digital lock balance valve  is a static hydraulic working condition balancing valve. It has an equal percentage flow characteristic curve, which is suitable for centralized volume adjustment, centralized quality adjustment and a volume adjustment system that changes the flow in stages. When the system flow changes At this time, the branches of the valve are installed, and the flow of each user will increase or decrease according to the proportion, maintaining the flow distribution scheme at the time of initial adjustment. SP45F Digital Locking Balance Valve  Technical Parameters 1. Nominal pressure 1.6MPa (2.5MPa must be booked); 2. Medium temperature: 0-150 ℃; 3. The theoretical characteristic curve is an equal percentage curve. When the valve weight is 0.3-0.5, the actual curve is a linear characteristic. 4. The structure length conforms to the structure length of stop valve and check valve in GB / T12221. Performance and charac...

Differential Pressure Control Valve Introduction of self-operated differential pressure control valve Does not require external energy to rely on the pressure change of the controlled medium to automatically adjust, automatically eliminates the residual pressure in the pipe network and the pressure deviation caused by the pressure fluctuations. Constant user inlet and outlet pressure difference, which helps stabilize the system operation. Automatic control system. Function of   Balancing Valve 1. The use of self-operated differential pressure control valve provides necessary conditions for household measurement. As everyone knows, household metering based on thermal charging improves the autonomy of thermal users and makes better use of free heat to save energy. If the system is not equipped with a self-operating pressure difference control valve, when the user adjusts the flow, it can only go to other users. In addition, The maximum pressure of the radiator temperature ...

To share with you as a  Butterfly Valve Supplier . Butterfly valve is a valve that uses a disc-shaped opening and closing piece to revolve around 90 ° to open, close or adjust the medium flow. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate, and fast, but also has good flow regulating function and closed sealing characteristics. It has been developed in recent decades. One of the fastest valve varieties.  Butterfly Valve  is very widely used. The variety and quantity of its use continue to expand, and it has developed to high temperature, high pressure, large caliber, high sealing, long life, excellent regulating characteristics, and multi-function of a valve. Its reliability and other performance indicators have reached a high level. Lug Type Butterfly Valve With the application of chemically resistant synthetic rubber to butterfly...

Advantages and disadvantages of  DIN F5 Gate Valve : 1. Small flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small. 2. Less effort when opening and closing. Compared with the shut-off valve, whether it is open or closed, the movement direction of the shutter is perpendicular to the medium flow direction. 3. High height, long opening and closing time. The opening and closing stroke of the shutter is large, and the lifting is performed by a screw. 4. Water hammer phenomenon is not easy to occur. The reason is the long shutdown time. 5. The medium can flow in any direction on both sides, which is easy to install. Gate valve channels are symmetrical on both sides. 6. The structure length (distance between the two end faces of the casing) is small. 7. Simple shape, short structure length, good manufacturing process and wide application range. 8. Compact structure, good valve ...

Gate Valve  is an opening and closing gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel and so on. The gate has a rigid gate and an elastic gate. According to different gates, the gate valve is divided into a rigid gate valve and an elastic gate valve. DIN F4 Gate Valve As a  Gate Valve Supplier , share with you how it works. The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonl...

The hand wheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited. 2. The double gate valve should be installed vertically (that is, the valve stem is in the vertical position and the handwheel is at the top). 3. The gate valve with bypass valve should open the ...
