Description


A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are the basic components in piping systems. Valve fittings, like pumps in technology, are often discussed as a separate category. The valve may be operated manually or with a hand wheel, handle or pedal, and may also be controlled to vary the pressure, temperature and flow rate of the fluid medium. The valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as required by external inputs (I. e., to adjust the changing set point of the flow through the pipeline). The automatic control valve does not need to be manually operated according to its input and setting, so that the valve can accurately control the various requirements of the fluid medium. Valves can also be divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual phase steel valves, plastic valves, non-standard customized valve materials, etc.

◆ Product overview

SP45/15F digital locking balance valve is a static hydraulic condition balancing valve. It has a flow characteristic curve of equal percentage. It is suitable for the volume regulation system of centralized volume regulation, centralized mass regulation and phased flow change. When the system flow changes, each branch of the digital locking balance valve is installed, and the flow of each user will increase or decrease proportionally, maintaining the flow distribution scheme during initial regulation. The digital locking balance valve also has the function of opening display and opening locking. Using this valve in heating and air conditioning water systems can achieve the effect of saving heat and electricity.
