3-way Ball Valve Maintenance

After installing a 3 Way Ball Valve in a pipeline, regular maintenance and care are required. For example, lubricate the valve stem regularly and open and close the valve frequently to prevent wear and tear on the ball, stem, and sealing surfaces. Maintenance and care should be tailored to the structural characteristics of the stainless steel ball valve.

1. Structural Features of Common Wafer-Type Ball Valves:

① The unique design of common wafer-type ball valves allows for frictionless transmission between the sealing surfaces, extending valve life.

② Common wafer-type ball valves generate an elastic seal based on torque.

③ The ingenious wedge-shaped design allows for an automatic seal that tightens as the valve closes, providing compensation between the sealing surfaces and zero leakage.

④ Compact size, light weight, easy operation, and simple installation.

⑤ Pneumatic and electric actuators can be configured to meet user requirements, meeting remote and programmable control needs.

⑥ Replaceable parts are available in various materials for various media and can be lined with corrosion-resistant materials (such as F46, GXPP, and PO).

⑦ A variety of continuous structures: wafer, flange, and butt-weld.

2. Maintenance of Stainless Steel Ball Valves (Commonly Wafer-Type Ball Valves)

The valve seats of most ball valves are made of elastic materials such as polytetrafluoroethylene. A sealing pair composed of metal and non-metallic materials is commonly referred to as a soft seal. Generally speaking, soft seals are easier to maintain and require less stringent machining accuracy and surface roughness.

Due to polytetrafluoroethylene's excellent self-lubricating properties, friction and wear with the ball are minimized. Furthermore, improvements in ball machining have reduced roughness, thereby extending the life of the ball valve.

There are two ways to reduce resistance in a piping system: one is to reduce the fluid flow rate, which requires increasing the pipe and valve diameters. This often negatively impacts the economic efficiency of the piping system, particularly in cryogenic transport systems (such as liquid hydrogen).
