【 Working Principle 】 :
The working principle of the JJ.BY1 single-flange pressure-tapping needle valve is the same as that of the stop valve. The valve core is a needle-shaped cone, and the sealing surface is conical. The valve core moves up and down along the centerline of the fluid to control the opening and closing of the valve or adjust the opening degree. Turning clockwise closes the valve, while turning counterclockwise opens it. This belongs to the lifting and rotating stem type (the handwheel and the valve stem rotate and rise and fall together, and the nut is set on the valve body).
【 Product Features 】 :
The design torque is low, which means it is lightweight and easy to operate.
2. The raw materials of all major components are traceable.
3. PTFE or flexible graphite sealing pressure device ensures no leakage during valve stem operation.
4. It features a compact structure, an attractive appearance, flexible use, tight connection and good sealing performance.
The JJ.BY1 single-flange pressure tapping needle valve is easy to install and disassemble, has a firm connection, is conducive to fire prevention and explosion prevention, has high pressure resistance, and good sealing performance. It is a type of valve used in power stations, oil refineries, chemical plants, and instrument measurement pipelines.
