Almost 40 years ago, Flowserve Worcester Controls’ original 3-piece valve was responsible for the development of the UK ball valve market. The Series 44 rapidly established itself as the industry standard for quality, reliability and long service.As you would expect, Worcester has developed and improved the Series 44 over the years to maintain its position as the 8-50mm valve design which others strive to equal. Now, Worcester’s new, larger valve, the 65-150mm Series 459, complements the Series 44 to offer you the most versatile, reliable and widely specified range of 3-piece ball valves available.
Gland nut does not need to be removed for actuator mounting thereby maintaining valve integrity
Anti-static stem design ensures electrical continuity between ball and body
Wide range of seat materials to suit customer applications
316 stainless steel ball as standard with pressure equalising hole to balance cavity pressure with line pressure when valve is open
PTFE body seals as standard for media compatibility but can be interchanged for alternative applications
