T961H High-pressure Feedwater Electric Control Valve
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 passing through the control valve and its opening degree when the pressure difference across the valve remains constant. The control valve is used to adjust the flow rate, pressure and liquid level of the medium. It automatically controls the opening degree of the valve according to the signals from the adjustment part, so as to adjust the flow rate, pressure and liquid level of the medium. Control valves are divided into electric control valves, pneumatic control valves, hydraulic control valves, etc. This section introduces 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. The control valve is 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 especially suitable for occasions with large flow rate, high pressure drop and small 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 rate, pressure, temperature and liquid level by means of power operation after receiving the control signal output by the adjustment control unit. It generally consists of an actuator and a valve. 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 characteristics, equal percentage characteristics and parabolic characteristics. 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.
