| Stainless Steel 1 PC Threaded Ball Valve
The stainless steel one-piece threaded ball valve is renowned for its simplicity and reliability in managing fluid flow. With a compact, single-piece body design, it's easy to install and offers a robust structure. Crafted from premium stainless steel, this valve boasts superior corrosion resistance and durability, suitable for various media such as water, steam, and chemicals. The 90-degree ball rotation ensures quick and precise flow control. The full port design reduces pressure drop, improving flow efficiency. The one-piece construction simplifies maintenance and minimizes leakage risks, making it ideal for industrial settings where dependability and performance are crucial.

| FAQ
(1) How long is the usual maintenance cycle for threaded ball valve?
The maintenance cycle of stainless steel one-piece ball valve is generally recommended to be carried out at least once a year. In harsh environments or cases of heavy use, more frequent maintenance may be required, such as semi-annual or quarterly. Regular cleaning, lubrication and inspection are an important part of the maintenance program to ensure optimal valve performance and extended service life.
(2) How to choose appropriate sealing materials?
- Fluid characteristics: Consider the chemical properties of the fluid, temperature, and pressure to determine the material's tolerance to the medium.
- Working conditions: Take care the humidity, temperature, external preaasure to ensure the material’s stability.
- Sealing material types: Commonly used sealing materials include rubber, plastic (such as nylon, PTFE), babbitt alloy, copper alloy, chromium stainless steel, chromium nickel stainless steel, etc
- R & D of new materials: With the development of nanotechnology, new nanomaterials may become the key to valve manufacturing, improving valve strength, corrosion resistance and thermal conductivity.
| Features of sealing materials | |
| Temperature resistance | Nitrile rubber: -20 ~80°C Silicone rubber: -60 ~ 200 ° C |
| Pressure resistance | Metal sealing materials such as stainless steel, copper, aluminum, titanium etc. |
| Abrasive resistance | Ethylene propylene rubber has good resistance to ozone and impact elasticity of various polar chemicals and solvents but poor oil resistance. |
| Aging resistance | Fluorous rubber etc. |
| Elasticity and plasticity | Rubber, plastic, PTFE etc. |
