Pneumatic 304 thin film regulating valve

The electric balance cage type regulating valve controls various high-pressure fluids at high and low temperatures, and is a pressure balanced regulating valve. The valve has a compact structure with S-shaped channels DHCB electric balance cage regulating valve is a pressure balanced regulating valve that controls various high-pressure fluids at high and low temperatures. The valve has a compact structure with an S-shaped channel and a guide vane that improves the fluid balance flow around the sleeve, resulting in low pressure drop loss, high flow rate, wide adjustable range, and high accuracy of flow characteristics, in compliance with the IEC534-1-1976 standard. The regulating valve has good dynamic stability, low noise, and minimal cavitation and corrosion. The leakage of the regulating valve complies with the ANSIB16.1 04 standard.

Electric single seat regulating valve is a new type of self operated regulating valve. Compared to manual regulating valves, its advantage is the ability to automatically adjust; Compared to electric control valves, its advantage is that it does not require external power. Practical application has proven that in closed water circulation systems such as hot water heating systems and air conditioning chilled water systems, the correct use of this valve can easily achieve flow distribution in the system; Can achieve dynamic balance of the system; It can greatly simplify the debugging work of the system; Can stabilize the working state of the pump, etc.

Pneumatic 304 thin film regulating valve The characteristics are:

1. The adjustable range is large, with an inherent adjustable ratio of 50, and the flow characteristics include straight lines and equal percentages.

2. The valve body is designed according to the principles of fluid mechanics, with a low flow resistance flow channel of equal cross-section, and the rated flow coefficient is increased by 30%.

3. The regulating cut-off type adopts a soft sealing structure valve core, which meets the VI level leakage standard (zero leakage).

4. The servo amplifier adopts deep dynamic negative feedback, which can improve the accuracy of automatic adjustment.

5. There are various forms of electric operators that can be used for 4-20mA DC or 0-10mA.DC.

6. The bellows sealed regulating valve forms a * seal on the moving valve stem, blocking fluid leakage.

7. Electronic electric control valves can be directly controlled by current signals to regulate valve opening, without the need for servo amplifiers.
