FAQs of Stainless steel 2piece ball valve

1. What material is the valve seat of a stainless steel 2-piece ball valve?

Plumberstar stainless steel 2-piece ball valves use PTFE valve seats.

PTFE seats work well in high and low temperatures. They resist acids, alkalis, oil, and many other chemicals. They have low friction, open and close smoothly, seal tightly, and last long.

They fit most media, such as water, gas, oil, steam, weak acids, and weak alkalis. They work for daily pipelines, heating, the chemical industry, and water treatment.

If you have special working conditions, we can offer other custom seats: reinforced PTFE, RPTFE, Viton, NBR, and more. They suit higher temperatures, stronger corrosion, or special media.

All valve seats pass strict seal and wear tests. They still seal well after thousands of openings and closings, no leaks or failures. They match the stainless steel valve body perfectly. This makes the whole valve more stable and durable.

2. Can the stainless steel 2-piece ball valve provide drawings customization?

Yes, Plumberstar provides drawing customization services. Our engineers can make professional drawings and produce products based on your actual working conditions, installation space, connection needs, and project standards.

We can adjust and optimize many parts of the ball valve: overall structure, connection type, port size, flange, thread standard, valve length, mounting holes, handle style, and more. We can use your original drawings, design plans, or parameters. We can also redraw 2D or 3D drawings to meet your standards, including ASME, DIN, GB, JIS, and others. We make sure the product fits your size, structure, seal, and installation needs.

Once you confirm the drawings, we make samples and mass-produce according to the final version. Bulk products will be exactly the same as the customized drawings.

If you have functional or usage requirements,our technical team can design the drawings first. We check details with you: structure, size tolerance, seal type, and pressure level. We communicate efficiently until you are satisfied.

All customized drawings are properly saved. It’s easy for reorders, changes, or technical tracing. We make sure every batch of products is stable and consistent.
