with heating jacket

Description:

According to the high viscosity characteristic of asphalt, based on our 75 years’ experience PR Raimondi has developed Fig.30/c heat preservation three-way stop valve and it is used for conveying high temperature asphalt mixing equipment, and lowering the labour intensity of highway construction personnel.The opening and closing of Fig 30/care realize by using the upper cylinder to charge air of a certain pressure. When air is charged into the qick-attachable coupling of the lower cylinder cover(15), the pressure inside the cylinder will be inreased, the piston will moved upward, the valve core will work togheter with thw piston thorught valve rod and piston rod, and here, the spring is compressed,the threeway-valve is opened and oil comes out from ther oil outlet. If the valve is not chrged with air, the oil outlet will always be closed due to the pressure function of the spring.Generally, the maximum pressure used is 1.MPa, and the minimum pressure used is 0.4 MPa. The upper and lower covers of the cylinder my be equpped with limit switch, which may be allocated by users upon demand, and connected to a PLC for automatic control.
