進口襯氟球閥(耐酸堿，耐腐蝕)內腔及球體均采用高壓注塑工藝，襯有耐腐蝕、耐老化的氟塑料或PTFE，故具有可靠的耐腐蝕性和密封性。能廣泛適用于化工、石油、冶金、醫藥、電力等工業控制系統。對酸、堿等強腐蝕性介質均能很好地應用retz The imported fluorine lined ball valve (acid and alkali resistant, corrosion resistant) adopts high-pressure injection molding technology for both the inner chamber and the ball, lined with corrosion-resistant and aging resistant fluoroplastics or PTFE, which has reliable corrosion resistance and sealing performance. It can be widely used in Industrial control system such as chemical industry, petroleum, metallurgy, medicine and electric power. It can be well applied to strong corrosive media such as acid and alkali

功能介紹 Function introduction

進口襯氟球閥(耐酸堿，耐腐蝕)電動襯氟球閥是由電動執行機構和O型襯氟球閥組成。閥體內腔及球芯均采用高壓注塑工藝襯有耐腐蝕、耐老化的聚全氟乙炳烯，故具有可靠的耐腐蝕性和密封性。電動襯氟球閥主要用于對生產過程中酸堿等強腐蝕介質的調節或切斷。電動執行機構內置伺服系統，無須另配伺服放大器，輸入4-20mA信號及220VAC/380V電源即可控制運轉 retz imported fluorine-lined ball valve (acid and alkali resistant, corrosion resistant) electric fluorine-lined ball valve is composed of electric actuator and O-type fluorine-lined ball valve. The inner cavity and ball core of the valve body are lined with corrosion resistant and aging resistant polyperfluoroethylene by high-pressure injection molding process, so they have reliable corrosion resistance and sealing. The electric fluorine lined ball valve is mainly used to regulate or cut off the strong corrosive media such as acid and alkali in the production process. The electric actuator is equipped with a built-in servo system, which can control the operation by inputting 4-20mA signal and 220VAC/380V power supply without additional servo amplifier
