The trunnion ball valve is a high-performance ball valve suitable for long-distance pipelines and general industrial pipelines.

Ball valve is a kind of valve used to intercept flow, regulate flow and change flow direction, which is widely used in petrochemical, metallurgy,

The size of the ball valve refers to the diameter size of the ball valve, usually in inches or millimeters. Common sizes are DN15, DN50, 2 inches, etc.

The working pressure of the ball valve refers to the maximum pressure that the valve can withstand, which should generally be within the operating pressure range of the valve.

Ball valve is a kind of valve widely used in pipeline and equipment systems, and its diameter is a key indicator to evaluate the size of ball valve.

This term refers to the decrease in fluid pressure due to frictional losses as fluid flows through a system.

Properly sized ball valves can improve system performance, service life and even economic viability.

Ball valves made of plastic are lightweight, high strength and strong corrosion resistance, and are often used for the control of low-pressure and low-flow media.

The medium is one of the first factors to consider when choosing a ball valve. Different media have different material requirements for ball valves.

If it is a problem at the spacer, the bolt should be tightened evenly and symmetrically, and a torque wrench should be used if necessary.

With proper operation and maintenance, semi-open, half-closed operation of a ball valve usually does not cause damage.

The valve body and bonnet materials shall conform to the GB/T12229 standard, and the main classifications are cast steel, stainless steel, copper alloy and cast iron.
