Manual modification of electric hard seal butterfly valve D343H-16C DN500

The manual modified electric hard seal butterfly valve D343H-16C DN500 adopts a "U" - shaped stainless steel sealing ring, which is precisely in elastic contact with the polished butterfly plate in three-dimensional eccentric manner. Solved the problem of traditional eccentric butterfly valves in opening and closing 0 #176; ～10 #176; The instantaneous sealing surface still suffers from sliding contact friction, achieving the effect of separation of the sealing surface when the butterfly plate is opened and sealing when the contact is closed, thus extending the service life and sealing performance.

Electric hard sealbutterfly valveAdopting a "U" - shaped stainless steel sealing ring, this precision elastic sealing ring is in three-dimensional eccentric contact with the polished butterfly plate. Solved the problem of traditional eccentric butterfly valves still having sliding contact friction on the sealing surface during opening and closing from 0 ° to 10 °, achieving the effect of separation of the sealing surface of the butterfly plate at the moment of opening and sealing upon closing contact, and extending the service life and sealing performance. Therefore, it is widely used in pipelines for corrosive media such as metallurgy, electricity, petroleum, chemical, air, gas, combustible gases, and water supply and drainage with medium temperatures ≤ 550 ℃. It is a device for regulating flow and cutting off fluids.

1. The butterfly valve has a simple, compact structure, light weight, easy installation and disassembly, and convenient maintenance;

2. This butterfly valve adopts a stainless steel "U" - shaped sealing ring, which has a certain degree of elasticity and excellent sealing performance with the butterfly plate under high and low temperature conditions;

3. The three-dimensional eccentricity of this butterfly valve has been rigorously calculated, and the "U" - shaped sealing ring has almost no friction with the butterfly plate, with a long service life and the function of tightening as it is closed;

4. The sealing surface of the butterfly plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life;

5. Electric butterfly valve structure *, the "switch" can be completed by simply rotating the valve stem 90 °. Flexible, convenient, effortless operation, not affected by the high or low pressure of the medium, and reliable sealing performance;

6. High temperature resistance, low temperature resistance, and corrosion resistance.

Electric Actuator
The CXR, HQ, or PSQ angular stroke fully electronic electric actuator is the driving device for O-type ball valves, designed with an integrated structure. It is powered by an AC220V power supply voltage and directly receives a unified standard signal (4-20mA, 0-10mA, or 1-5VDC, 0-10VDC), converting it into displacement corresponding to the input signal. It moves at an angular displacement (0-90 °) to change the opening of the valve core. Therefore, a certain input signal corresponds to a certain position opening, achieving proportional action. The two position switch type accepts power from AC220V or AC380V, achieves switch action through motor forward and reverse rotation, and simultaneously outputs valve position indication signal, which is a high-precision, high-performance, and high reliability product.
