Electric piston type flow regulating and pressure regulating valve is a kind of control valve. It cooperates with the automatic control system when working and is mainly used to control the pressure before the valve (behind the valve), the flow rate through the valve, and the liquid level in the pool. The valve works on the principle of compound hole hedging and energy dissipation, which can reduce the high pressure before the valve to the low pressure after the valve; it can also control the flow rate through the valve or the level of the liquid level in the pool by controlling the size of the flow area of the valve port. Can be used as reservoir dam discharge valve.
Features
1.The valve is optimal in the traditional flow control valve characteristics lies in its structural design and material selection, so not afraid of sewage clogged chute, not afraid of fouling phenomenon, not easy to jamming.The drive device is significantly reduced.
2. The valve automatically adjusts the pipeline medium parameters pre-set value, so that remains constant within a certain precision,and accuracy of the range can also be adjusted.
3. The valve has good resistance to cavitation, the ribs of the body wall of both the role of the rectifier board can be distributed the water to prevent cavitation.But also reduces the valveNoise and vibration of the piston.
4.The valve control system can be integrated electronic circuit, small size,reliability,high sensitivity,easy installation and commissioning.
5.Fully closed the leakage is zero, can be used as a cut-off valve. You do not have to separate the cut-off valve.
6.Such as the degree of control and accuracy requirements are not very high,the valve control can be used manually or ordinary electric form.
7.Can be horizontal (such as the position shown) installed, can also be installed vertically.
