T961H High-pressure Feedwater Electric Control Valve
Other Products
I. Product Introduction:
The flow characteristic of the high-pressure feed electric control valve refers to the relationship between the relative flow of the medium through the control valve and its opening degree when the pressure difference across the valve remains constant. The control valve is used to regulate the flow, pressure and liquid level of the medium. It automatically controls the opening degree of the valve according to the signals from the regulating part, so as to adjust the flow, pressure and liquid level of the medium. Control valves are divided into electric control valves, pneumatic control valves, hydraulic control valves, etc. This section will introduce two types: electric control valves and pneumatic control valves. A control valve consists of two parts: an electric actuator or a pneumatic actuator, and the valve body. Control valves are usually divided into two types: straight-through single-seat type and straight-through double-seat type. The latter has the characteristics of large flow capacity, small unbalance force and stable operation, so it is usually particularly suitable for occasions with large flow, high pressure drop and low leakage.
II. Product Features:
The control valve, also known as the control valve, is a final control element in the field of industrial automation process control. It changes the process parameters such as medium flow, pressure, temperature and liquid level by means of power operation after receiving the control signal output from the regulating control unit. It generally consists of an actuator and a valve body. According to the stroke characteristics, control valves can be divided into straight stroke and angular stroke; according to the power used by their matched actuators, and according to their functions and characteristics, they are divided into three types: linear characteristic, equal percentage characteristic and parabolic characteristic. Control valves are suitable for media such as air, water, steam, various corrosive media, slurry, oil products, etc. Its English name is control valve. Common classifications of control valves include: pneumatic control valves, electric control valves, hydraulic control valves, and self-operated control valves.
