Why is the regulating valve also called a full function valve

1.High compressive strength

Good pressure resistance function ensures the safety of the valve. The valve body structure of the full-function control valve is a single piece, which improves the pressure resistance. The high pressure adopts a forged structure, which improves the compressive strength of the valve body, and the compressive strength can reach more than 32MPa.

2, good temperature resistance

The good temperature resistance function ensures that the valve can adapt to different temperatures. The full-function regulating valve adopts a rigid and flexible combined elastic hard seal to solve the problem of core and seat package card caused by expansion at high temperature; the use of high temperature wear-resistant packing to ensure the reliability of the valve stem sealing at high temperature.

3.Good anti-blocking function

The good anti-blocking function also guarantees the normal operation of the valve in the case of dirty media. The full-function control valve has the characteristics of difficult to settle through the media, simple flow path, good self-cleaning function, and few dead zone vortices. It has become the first choice for applications with dirty media.

4, strong corrosion resistance

Good corrosion resistance can ensure that the valve can resist the damage of medium corrosion, cavitation and erosion, and prolong the service life. Full-function control valve adopts corrosion-resistant and erosion-resistant materials and preventive measures, and has good corrosion resistance.

5, good adjustment function

The regulating function is one of the main functions of the regulating valve. Its flow characteristics are: small opening performance; adjustable ratio R; flow coefficient; regulating speed. Full-function control valve R = 100, making small opening degree good adjustability; Kv value is large, which is 2 ~ 3 times of single and double seat valve and sleeve valve.

6, good cut-off function

The shutoff function reflects the intrinsic quality of the valve. The standard leak rate of straight-stroke valves is usually 10 to 10; the standard leak rate of full-function ultra-light control valves is 10, which is 100 to 1,000 times higher than that of single and double seat valves and sleeve valves.

7, overcome the large pressure difference

The function of overcoming the differential pressure is a prerequisite for ensuring the cut-off and is inseparable from the cut-off function. The single-seat valve has a small leakage and a small allowable pressure difference, and the double-seat valve has a large allowable pressure difference but a large leakage. The full-function regulating valve solves the problem of large pressure difference and small leakage requirements. It allows the pressure difference to reach PN.

8.Good appearance and light weight

The full-function control valve adopts an integrated valve body structure and optimized appearance design, and is equipped with a simple and reliable direct connection method to connect with an electric actuator . The structure is compact, small in size, light in weight, and good in appearance. The full-function control valve weighs only 40Kg (electronic).
