On the way forward, let Xinhui Valve solve your problems! [Regulating valve] can be used in: chemical, petrochemical, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction, and other fields.

[Control valve] valve body type selection: There are many types of valve bodies for control valves, and the commonly used valve body types include

① straight-through single seat

② straight-through double seat

③ angle

④ diaphragm

⑤ small flow

⑥ three-way

⑦ eccentric rotation

⑧ butterfly

⑨ sleeve Cylinder type

⑩ spherical and so on.

[Regulating valve] The following considerations can be made in the specific selection:

(1) The shape and structure of the valve core: It is mainly considered according to the selected flow characteristics and unbalanced force.

(2) Wear resistance: When the fluid medium is a suspension containing a high concentration of abrasive particles, the internal material of the valve should be hard.

(3) Corrosion resistance: Since the medium is corrosive, try to choose a valve with a simple structure.

(4) The temperature and pressure of the medium: when the temperature and pressure of the medium are high and the change is large, the valve core and the valve seat material should be selected with small changes in temperature and pressure. When the temperature is 250°C, a radiator should be added. .

(5) Prevent flash evaporation and cavitation: Flash evaporation and cavitation only occur in liquid media. In the actual production process, flash evaporation and cavitation will form vibration and noise, shorten the use of the valve, so the valve should be prevented from flashing and cavitation when selecting the valve. Overview of ZMAS High Pressure Angle Control Valve:

ZMAS High Pressure Angle Control Valve is composed of pneumatic multi-spring diaphragm actuator and low flow resistance single seat valve. The new actuator is low in height, light in weight and easy to install. The new valve body has a compact structure, a smooth flow channel and a large flow coefficient. This product operates stably, has good action characteristics, small valve seat leakage, accurate flow characteristics, and a wide adjustable range. It has the advantage of achieving high quality control in the application. Products include standard type, adjustable cut-off type, bellows seal type, jacket insulation type, etc.
Variety. Applicable to various grades of liquid temperature ranging from -200^ to +560C. (Accessories available: positioner, air filter pressure reducer, position retaining valve, travel switch, valve position transmitter, solenoid valve, handwheel mechanism, etc.)

[Regulating valve] It consists of two parts: an electric actuator or pneumatic actuator and regulating valve. The regulating valve is divided into an electric regulating valve, a pneumatic regulating valve, and a hydraulic regulating valve (self-operated regulating valve). The regulating valve is used to regulate the flow, pressure, and liquid level of the medium. According to the signal of the adjustment part, the opening of the valve is automatically controlled, so as to achieve the adjustment of medium flow, pressure, and liquid level. [Control valve] is usually divided into two types: straight-through single-seat control valve and straight-through double-seat control valve. The latter has the characteristics of large flow capacity, small unbalance, and stable operation, so it is usually suitable for large flow, high-pressure drop, and Occasions with little leakage. The flow capacity Cv is one of the main parameters for selecting the control valve. The flow capacity of the control valve is defined as when the control valve is fully opened, the pressure difference between the two ends of the valve is 0.1MPa, and the fluid density is Lg/cm3, the flow rate per hour is The flow rate of the diameter control valve, called the flow capacity, also called the flow coefficient, is expressed in Cv, the unit is t/h, and the Cv value of the liquid is calculated as follows.
