Sewage ball valve >>>Back
Overview:
The company designed the overall high temperature ball valve is a new type of sealing material for the valve seat, the ball valve sealed by the same product PTFE, the service life has increased by 3-5 times. It has the advantages of stable performance, reliable sealing, small friction, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance and long service life. "Roland" brand high temperature ball valve and globe valve, plunger valve, sewage valve, structure length In line with the expansion of the use of ball valves, widely used in petroleum, chemical, rubber, paper, pharmaceutical and other industries, can replace the stop valve, plunger valve, fast drain valve. Applicable medium: water, steam, heat transfer oil and other acids, use temperature: ≤350 °C

Structural characteristics and principle of action:
The ball and seal ring of this type of valve adopt special processing technology and new sealing material of Zui, which makes the surface roughness and roundness of the ball meet the standard requirements, thus improving the sealing performance, service life and high temperature resistance.
The clockwise handle moves the valve stem to drive the ball to rotate, allowing the medium to pass smoothly.
