The valve body is the heart of any industrial valve. It determines the strength, pressure rating, corrosion resistance, and long-term durability of the entire valve assembly. At Perfect Engineers, we offer precision-engineered ball valve bodies in a wide range of materials and construction designs, tailored to meet the exact requirements of fluid type, pressure class, temperature range, and industry standards.
Whether you’re sourcing for chemical plants, oil refineries, HVAC systems, water treatment facilities, or food & pharma lines, understanding valve body material selection and design types is essential for long-lasting performance.
The valve body is the main pressure-retaining component of a ball valve. It houses the ball, stem, seats, and sealing components, and connects to piping systems via threaded, flanged, welded, or clamp-type ends.
It plays a key role in:
| Material | Suitable For | Key Benefits |
| WCB (Cast Carbon Steel) | Oil, gas, water, steam | High strength, economical |
| A105 (Forged CS) | High-pressure pipelines | Compact, durable |
| SS304 (CF8) | Water, air, non-corrosive chemicals | General corrosion resistance |
| SS316 (CF8M) | Acids, chemicals, food, pharma | Excellent corrosion resistance |
| Duplex / Super Duplex | Seawater, chlorides, high pressure | Strength + superior pitting resistance |
| Alloy 20 | Sulfuric acid, aggressive fluids | Anti-corrosive specialty alloy |
| Monel | Saltwater, hydrocarbons | Ideal for marine/offshore use |
| Inconel / Hastelloy | High temp & chemical resistance | High-performance alloy applications |
| Brass / Bronze | Potable water, air, gas | Good machinability & sealing |
| PVC / CPVC | Water, RO, agriculture, chemicals | Lightweight, corrosion-proof |

Only for mild chemicals. For corrosive acids, SS316, Alloy 20, or Hastelloy are recommended.
They allow easy cleaning, seal replacement, and maintenance without disturbing the pipeline.
Yes—for low-pressure, corrosion-prone systems, PVC or CPVC is ideal. Not suitable for high temp or pressure.
Yes—A105 is denser and stronger, making it ideal for high-pressure and vibration-prone systems.
