Cast Iron Rustproof Floating Ball Valve Anticorrosive 1.6 Mpa High Temperature
Cast Iron Pressure 1.6 Mpa High Temperature Ball Valve Floating Ball Valve
Usage
This valve applies to the water, steam or oil pipeline which is noncorrosive medium and the pipeline must be the working nominal pressure is ≤1.6 mpa
Structure and action principle
1. Qj41mf-16 is flange connection, and the product complies with GB / T 15185 standards for iron and copper ball valves.
2. The valve is an integrated high-temperature ball valve. The valve is composed of valve body, ball, valve stem, handle and other parts. The handle parallel to the pipeline axis indicates that the valve is in the open position, and perpendicular to the pipeline axis indicates that it is in the closed position. It can be opened and closed by turning the handle 90 °; It has the advantages of stable performance, reliable sealing, small friction force, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, long service life and so on.
