Compact Isolation for pipe to instrument interfacing

Published: 13 July 2012 - Heather Ramsden

A new monoflange-style ball valve for interfacing instruments to process piping has been launched by the instrumentation products division of Parker Hannifin.

The bidirectional valve range - designated Monoball – is available in four sizes with bores of 10, 15, 20 or 25 mm and offers a full cold working pressure rating of 6,000 PSI (414bar) with 100 per cent bubble-tight shut-off.

Monoflange-style construction makes the new valve lighter and more compact than conventional flange-to-flange mounted ball valves. This makes it suitable for space and weight-sensitive applications such as offshore platforms, as well as the many common isolation requirements which are found in oil, gas and chemical processing installations. Monoball’s compact construction makes it a versatile building block for configuring multi-valve manifold arrangements. This provides a simple means of coupling instruments closely to process piping, to allow safe removal of an instrument valve if it needs to be replaced due to damage or plugging.

Additional construction features employed by Parker further enhance reliability and safety for users. The valve body is machined from a single forging, reducing potential leak paths to the minimum. In addition to NPT threaded interfaces, Parker can also supply the valve with two-ferrule tube fitting ends, thereby eliminating taper threads and the subsequent need for thread sealants, which can be a source of problems in the field.
