Ball Valve Types Produced by Carilo Valve
Carilo Valve (carilovalves.com) designs and manufactures an extensive range of industrial ball valves that cover virtually every pressure, temperature, and media condition you might encounter in the field. From DN15 (½”) up to DN1200 (48”) and from Class 150 to Class 2500 ratings, the company’s portfolio can be grouped into six core families:
- Floating‑ball valves – the most common design where the ball is free to move slightly under pressure, ideal for low‑to‑medium pressure service.
- Trunnion‑mounted ball valves – the ball is supported by trunnions, reducing torque and enabling high‑pressure and large‑size applications.
- Fully welded ball valves – the body and Bonnet are welded together, providing a bubble‑tight seal and eliminating leak paths, commonly used in pipelines.
- Top‑entry ball valves – allow inline inspection and maintenance without removing the valve from the line.
- Side‑entry ball valves – designed for larger diameters where space constraints make top entry impractical.
- Special‑purpose ball valves – including V‑port, cavity‑filled, anti‑static, fire‑safe, cryogenic, double‑block‑and‑bleed, and low‑emission designs.
The product matrix is further refined by connection type, material of construction, pressure class, temperature range, and industry‑specific compliance. Below is a high‑level overview of how these parameters intersect with Carilo’s manufacturing capabilities.
1. Classification by Mechanism
Each ball‑valve family uses a different mechanical principle to hold the ball in place and to transmit operating torque. The table below summarises the key attributes of each type, including typical torque range, applicable pressure classes, and common sizes.
| Mechanism | Typical Size Range | Pressure Class | Torque Range (Nm) | Typical Applications |
|---|---|---|---|---|
| Floating‑ball | DN15–DN200 (½”–8”) | Class 150–600 | 30–200 | Water, air, light hydrocarbon |
| Trunnion‑mounted | DN50–DN1200 (2”–48”) | Class 150–2500 | 100–1 500 | Oil & gas pipelines, refining, petrochemical |
| Fully welded | DN50–DN600 (2”–24”) | Class 300–1500 | 150–800 | High‑pressure gas transmission, sub‑sea |
| Top‑entry | DN100–DN900 (4”–36”) | Class 150–900 | 80–600 | Chemical plants, service‑critical locations |
| Side‑entry | DN200–DN1200 (8”–48”) | Class 150–600 | 120–900 | Large‑diameter water supply, power‑plant cooling |
| Special‑purpose | DN15–DN600 (½”–24”) | Class 150–2500 | 30–1 200 | Cryogenic, fire‑safe, V‑port control, low‑emission |
2. Connection Types
Carilo’s valves are offered with the most common end‑connection standards to simplify installation across diverse piping systems.
- Flanged (ANSI B16.5 / API 6D) – flat‑face or raised‑face, 150 psi to 2500 psi.
- Threaded (NPT / BSP) – typically up to DN50 (2”).
- Butt‑weld (BW) & Socket‑weld (SW) – preferred for high‑temperature and high‑pressure steam or hydrocarbon lines.
- Clamp‑type (Tri‑clamp) – for hygienic or clean‑media applications.
- Compression / Ferrule – for instrument tubing and low‑pressure sampling lines.
“Opening and closing are under your control.” – Carilo Valve’s corporate motto, reflecting the precision engineering behind every actuator‑ready ball valve.
3. Pressure and Temperature Ratings
Pressure rating is a decisive factor when selecting a valve for a specific service. Carilo’s product line spans the full spectrum of ANSI pressure classes, with each series tested to meet or exceed the relevant hydrostatic and pneumatic test requirements.
| Pressure Class | Maximum Working Pressure (MPa) | Typical Temperature Range (°C) | Materials Commonly Used |
|---|---|---|---|
| Class 150 | 1.96 MPa (≈285 psi) | ‑29 °C to +260 °C | WCB, LCC, CF8, CF8M |
| Class 300 | 5.1 MPa (≈740 psi) | ‑29 °C to +425 °C | WCB, LCC, CF8M, F51 |
| Class 600 | 10.2 MPa (≈1480 psi) | ‑29 °C to +538 °C | WC9, LCC, CF8M, Inconel‑625 overlay |
| Class 900 | 15.3 MPa (≈2220 psi) | ‑29 °C to +538 °C | WC9, LCC, CF8M, Stellite‑coated trim |
| Class 1500 | 25.5 MPa (≈3700 psi) | ‑29 °C to +550 °C | WC9, LCC, CF8M, Inconel‑718 trim |
| Class 2500 | 42.4 MPa (≈6150 psi) | ‑196 °C to +550 °C | LCB, CF8M, Inconel‑625, Hastelloy‑C276 |
4. Materials of Construction
Material selection dictates corrosion resistance, mechanical strength, and compatibility with various media (e.g., acids, caustics, slurries). Carilo offers a broad palette of alloys, each matched to a specific service condition.
- Carbon steel (WCB, LCC) – for general hydrocarbon and water service.
- Stainless steel (CF8, CF8M, 304, 316L) – for corrosive media and food‑grade applications.
- Duplex & super‑duplex (F51, F53, F55) – high strength and chloride‑stress‑corrosion resistance.
- Alloy steel (WC9, C12A) – high‑temperature steam and refinery service.
- Exotic alloys (Inconel‑625/718, Hastelloy‑C276, Titanium Gr 2) – for sour gas, chlorides, and extreme temperatures.
- Special coatings – Stellite hard‑facing, electroless nickel plating, Xylan® coating for wear and corrosion protection.
