Do Stainless Steel Valves Rust?

Not rust characteristics of the stainless steel material are relative, not absolute. In some special environments, stainless steel valves can also rust

The Methods of Reducing Valve Opening Torque

There are four ways to reduce the opening torque of a valve: optimizing the valve design, choosing the right materials, improving operating conditions, and regular maintenance.

What are the factors that affect the magnitude of the valve opening torque

The magnitude of the opening torque of a valve can be affected by the type and mechanism of the valve, the size and pressure rating of the valve, the nature of the medium and the operating conditions.

What are the Necessary Characteristics of Valve Packing?

Valve packing is the sealing material that be installed between the valve stem and bonnet, its main role is to prevent the medium from the valve stem and bonnet gap leakage. When the valve is closed, packing through the close contact with the valve stem, forming a sealing barrier to prevent the outflow of media; when the valve is open, packing can adjust its own sealing status with the movement of the valve stem, to ensure that in different valve positions can maintain good sealing.

Applicable Occasions of Ball Check Valve

Ball check valve because the sealing member is rubber-covered ball, so the sealing performance is good, reliable operation, good resistance to water strike; and because the sealing member can be a single ball, and can be made into a multi-ball, so it can be made into a large caliber.
