Monoflange ball valve

for pipe-to-instrument interfacing

Posted on May 10, 2012 - ( views)


A monoflange-style ball valve for interfacing instruments to process piping has been launched by Parker Hannifin. The bidirectional valve range - designated Monoball - is available in four sizes with bores of 10, 15, 20 or 25mm and offers a full cold working pressure rating of 414 bar with 100% 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 ideal for space- and weight-sensitive applications such as offshore platforms, as well as the many common isolation requirements found in oil, gas and chemical processing installations.

In addition to being used an isolation valve, 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 the safe removal of an instrument valve if it needs replacing 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 cause be a source of problems in the field.

As standard, Monoball valves are available in stainless steel (ASTM A182 F316/F316L), carbon steel (ASTM A350 LF2/A105), or Duplex (ASTM A182 F51) materials. Other high performance alloys, and NACE MR 0175/ISO 15156 compliant versions are available on request. Depending on the bore size chosen, the valve comes with flange sizes from 1/2 to 2 inches NB (15 to 50 DN), compatible with ANSI B16.5 flange classes from 150 to 2500. Users can also specify the valve with a range of seat materials, including PTFE and PEEK. A fire-safe version is optionally available.
