The electric single seat regulating valve is a kind of pressure balance type regulating valve. Accept the DC current signal from the instrument, change the flow of the transferred medium, so that the controlled process parameters remain at the given value. Widely used in electric power, metallurgy, chemical, petroleum, textile, pharmaceutical, paper and other industrial sectors of the production automation control.

Electric balance cage single seat control valve control a variety of high temperature, low temperature of the high pressure fluid, is a pressure balance of the control valve. Valve structure is compact, there are S streamlined channel. DHCB electric balance cage control valve, control a variety of high temperature, low temperature high pressure fluid, is a pressure balance of the control valve. Valve structure is compact, there is S streamlined channel, also has a sleeve to improve the flow of fluid around the sleeve of the flow of the wing, so that the pressure drop loss of small, large flow, adjustable range, high precision flow characteristics, in line with IEC534- 1-1976 standard. The dynamic stability of the control valve is good, the noise is low and the cavitation corrosion is small. The leakage of the regulating valve complies with ANSIB16.1 04 standard.

classification:

Electric single seat control valve

Electric sleeve single seat control valve

Electric cage single seat control valve

advantage

Electric single-seat control valve is a new type of self-regulating valve relative to the manual control valve, which has the advantage of being able to automatically adjust; relative to the electric control valve, it has the advantage of no external power application practice has proved that in the closed water cycle System (such as hot water heating system, air conditioning chilled water system), the correct use of this valve, you can easily achieve the system's flow distribution; can achieve the dynamic balance of the system; can greatly simplify the system debugging; Working status and so on.

Features

Electric single-seat control valve is characterized by:

1, adjustable range, the inherent adjustable ratio of 50, the flow characteristics of a straight line and equal percentage.

2, the valve body according to the principle of fluid mechanics design of the cross-section low flow resistance flow, the rated flow coefficient increased by 30%.

3, adjust the cutting type using soft seal structure spool, up to grade VI leakage (zero leakage).

As shown in Figure 4, the servo amplifier with deep dynamic negative feedback, can improve the accuracy of automatic adjustment.

5, electric manipulator in various forms, applicable to 4 ~ 20mA.DC or 0 ~ 10mA.DC.

As shown in Figure 6, the bellows seal type regulating valve to the movement of the stem to form a complete seal, blocking fluid leakage.

As shown in Figure 7, the electronic type electric control valve can be directly controlled by the current signal valve opening, no servo amplifier.
