ZXN New Series Pneumatic Thin Film Double Seat Regulating Valve

Pneumatic diaphragm double seat regulating valve, pneumatic three-way regulating valve, electric three-way diversion regulating valve, pressure regulating valve, also known as regulating valve, flow control valve, flow controller, dynamic balance valve, flow balance valve, is an intuitive and simple flow regulation control device,

The structure of a regulating valve is usually composed of an electric or pneumatic actuator and a valve body. There are mainly two types of straight stroke: straight through single seat and straight through double seat. The latter has the characteristics of large flow capacity, small imbalance, and stable operation, so it is usually particularly suitable for situations with high flow rate, high pressure drop, and low leakage. The main types of angular stroke include V-shaped electric regulating ball valves, pneumatic diaphragm cut-off valves, eccentric butterfly valves, etc. This type of valve should generally be installed horizontally in pipelines.

The application of flow control valves in pipeline networks can directly set the flow rate according to the design. The valve can automatically eliminate the flow deviation caused by residual pressure head and pressure fluctuations in the pipeline under the action of water, and maintain the set flow rate unchanged regardless of changes in system pressure. These functions of the valve enable the adjustment of pipeline flow to be completed in one go, turning the adjustment work into a simple flow distribution and effectively solving the hydraulic imbalance of the pipeline network. Flow regulating valves are mainly used in water systems such as centralized heating (cooling), to distribute the flow of the pipeline network according to demand, eliminate hydraulic imbalance in the water system, solve the problem of uneven heating and cooling, and can save energy and electricity by 15% -20%.
