1, ApplicationHV series gate valve is the main flow control transmission equipment for powder, grain materials, and small particles. The wear parts of this gate valve is used of wear-resistant materials, meanwhile fully considered the hard characteristics of particle, so there was almost no valve jammed phenomenon, it can operate in a poor environment for a long-term without troubles. HV Series gate valve is equipped with the manual, electric drive device to control valve’s operation, is the ideal facility for flow regulation2,Structure Features(1)It has a pleasing appearance, compact structure, small size, light weight, non resistance, and no angle limit.(2)The valve plate is using high-quality heat-resistant materials, with good properties of anti-corrosion in high temperature, wear resistance, no leakage. (3)The German original (SEW) Schneider transmission motor can achieve reversion, smooth transmission with low vibration and noise rate.3,Working PrincipleHV series manual gate valve is operated through the rotation of hand wheel. The clockwise rotation of the hand wheel drives the valve plate to one side of the hand wheel through the rotation of the screw, thus valve is increase opened. When the hand wheel is an anti-clockwise rotation, the valve is increase closed. HV-Series electric gate valve is drive by Schneider transmission motor. When the motor is rotating which drives the valve plate move to one side of the motor through the screw, and thus the valve increased opened. When the motor runs reversely, the valve plates moving away from the motor side, and the valve is increase closed.(1),Technical ParametersNominal Path(mm)200250300400500600Route(mm)200250300400500600Handwheel(mm)φ200Transimission MotorRF37DT90L4RF37DT90L2RF37DV100L4PowerAC220V,AC380V 50HzMotor power(KW)0.751.52.23.0Speed(r/min)71119146148Temperature(°C)≤550
