What is the function of electric ball valve and plug valve


The electric ball valve and plug valve can scrub the sealing surface in the process of opening and closing, so it is suitable to be used in the medium with suspended particles. At present, no matter in the petroleum, chemical industry, or other professional piping system, valve application, operating frequency and service are constantly changing, so we should control or eliminate even minor leakage. If the back and forth movement of the closing member to the seat is vertical, particles may be trapped. Therefore, this valve is only suitable for fundamentally clean media unless the sealing surface material allows the insertion of particles.
 What is the function of electric ball valve and plug valve
1. The control of pipeline is valve. The service and reliable performance of valve in various fields are unique. Valve inspection and maintenance after purchase, valve repair and maintenance is not timely, resulting in valve repair and leakage or ineffective switch; valve is not punctual maintenance and pressure test, even used for many years without cleaning, pressure test and technical appraisal.
2. As a result, the debris accumulated in the valve, and the valve was not closed tightly, resulting in serious oil leakage and oil leakage; the valve was not closed after maintenance, or the pipe orifice was not blocked after the valve was removed; the valve dust flange gasket was made of oil resistant and pressure resistant materials. Therefore, it is necessary to strengthen the inspection of valves, and strive to prevent accidents in the bud.
