| Petroleum Products - Adapters, Caps, Couplings, Interlocks, API and Vapor Valves |
| |
| Dixon products are engineered for dependable, long service life and designed for easy, low cost maintenance. Where possible; modular systems are incorporated with common parts to minimize inventory of repair items. |

 |
| |
| 4" API Valves |
|
| API Valves are used for bottom loading and unloading of petroleum tankers. Valve nose shape and opening comply with American Petroleum Institute standard (API RP-1004) enabling Dixon API valves to interchange with competitor items made to the same specification. Two styles are available; a load model without handle and a load/unload model with a handle to allow manual opening. |
|
• Unique flow and fluid level sight indicators are available
• Load/unload versions feature an ergonomically curved handle that opens with a short 62° stroke. Can be ordered with a fixed or removable handle
• Chemical resistant crank seals and poppet seal (Teflon® seals optional)
• Any required maintenance is simplified, can be completely rebuilt without removing the valve from the tank
• The ALH (anodised aluminium hard coat) nose ring can be rotated to provide a fresh cam service |

| Gravity Drop Adapters |
|
Gravity drop adapters attach and seal directly against openable API's and allow drop hose with standard cam and groove couplers to clamp on and transfer petroleum from the API. Dixon manufactures two styles of gravity drop adapters: 1) standard one piece and, 2) a 2 piece bolt together design with sight glass. Both are Dixon quality cast construction with bronze cam arms and Buna O-Ring seals (Viton O-Rings available upon request).
• Quality cast aluminium body with inside lip to hang on API while clamping
• Inexpensive replacement of Buna O-Ring seal (Viton seal available)
• Bronze cam arms with stainless steel pins, finger rings
|
 |
• Consists of a 4500 ring assembly and an outlet which contains mounting bolts, sight glass and seals
• Customer assembly required (see sketch)
• Order 4500 ring and outlets separately |
