Belfield Valve Decants a Variety of Liquids at different gravities

Slide

Belfield Decantation Valve

The Belfield Valve is a precision-engineered automatic decantation system capable of detecting and separating liquids with as little as a 5% difference in specific gravity. Operating at a design pressure of 75 psig (tested to 112.5 psig) ensures efficient phase separation without manual intervention. Constructed from stainless steel or carbon steel with stainless steel internals, it is highly durable and resistant to process conditions.

Belfield Valve Explained

The Belfield valve has been acclaimed, the easiest, most efficient way to decant and recover a wide variety of liquids possessing different specific gravities! It is automatic, extremely sensitive, versatile and provides users with a proven method for decanting or separating the heavier of two liquids. It also eliminates the many problems which occur during manual decanting of one phase in a wide range of multiphase systems, including:

No Waste

No loss of product due to human error, especially where little or no colour variation exists between phases.

Detection

Detects and retains or rejects valuable interface materials containing recoverable products.

Safety

Serves as a safety device on effluent discharge systems reducing and/or eliminating pollution problems.

Automatic

Requires minimal attention, service and maintenance thereby reducing labour costs drastically.

Stainless Steel

Standard body materials of construction are either carbon steel or stainless steel, in both cases the internals are constructed from stainless steel.

Some of our clients

Trusted by industry leaders worldwide, the Belfield Valve is relied upon by major companies in petroleum refining, chemical processing, and wastewater management. Our technology has been integrated into critical operations where precision, reliability, and efficiency are paramount.

How does it work?

Valve operation

Ballasting the float. The float is ballasted by adding water via the hexagon headed screw in the top of the float to give the float positive buoyancy in the heavier liquid and negative buoyancy in the interface or lighter liquid, as required.

Belfield Valve

Real Performance now meets real results.

The Belfield Valve operates on the principle of differential specific gravity, enabling precise phase separation with as little as a 5% density difference. Designed for high-turbulence, self-cleaning performance, it ensures efficient liquid recovery in crude oil storage, reclaimed oil processing, and floating roof tank drainage.
