Materials for Valve Bodies
| Material | Grades | Applications |
|---|---|---|
| Stainless Steel | 316, 316L | General purpose, good corrosion resistance |
| Duplex Steel | 2205, 2507 | Chloride resistance, higher pressure |
| Inconel | 718, 625 | High temperature, extreme corrosion |
| Titanium | Grade 2 | Seawater, extreme corrosion resistance |
| Carbon Steel | 4140, 4340 | Standard valve bodies, cost-effective |

Valve Bodies FAQ
What valve bodies can you manufacture?
Ball, gate, globe, butterfly, and check valve bodies. All sizes, pressure ratings, and port configurations. SAE, ISO, API-standard designs available.
What materials are best for corrosive valve applications?
Stainless steel 316 and 316L for general corrosion. Duplex 2205 and super duplex 2507 for chloride resistance. Inconel for high-temperature corrosion. Titanium for seawater.
What tolerances can you hold on valve sealing surfaces?
Seat sealing surface tolerances held to ±0.05mm. Precision grinding achieves ±0.02mm flatness. Bore and port concentricity within tight limits for optimal valve sealing.
What is the typical lead time for valve bodies?
Simple bodies: 3–4 weeks. Medium complexity: 4–6 weeks. Complex multi-port assemblies: 6–8 weeks. Lead times depend on material, port count, and pressure rating.
Can you manufacture valve bodies to API standards?
Yes. API 600 (gate valves), API 609 (butterfly valves), API 6FA (full opening fire-safe valves) designs available. Pressure rating and certification available.
Do you offer surface treatments for valve seats?
Yes. Seat hardening, nitriding, and hard-facing available to improve valve life. Passivation for stainless valve bodies included.
