Circor brand PV announces 50 year anniversary

Circor International, a manufacturer and marketer of differentiated technology products and sub-systems, joins their brand Portland Valve (PV) in celebrating their 50 year anniversary. Originally incorporated on June 29, 1973, with 5 employees, PV has grown to become a standard name in valves for both submarines and surface vessels over the past 50 years.

Portland Valve manufactures a full line of ship service ball valves and other specialty valves for submarine applications as well as specialty valves for aircraft carriers and destroyers. PV also provides repair services for bleed air control valves and all valves that we manufacture.

In 2004, PV was acquired by Colfax Corporation. During this time PV expanded its product base with a new design Bleed Air valve line for the DDG51 Class destroyer. This was a brand-new PV design that replaced a legacy product and was PV’s first proprietary design valve for a specific ship class. PV valves are currently installed on hull DDG 95 and forward.

PV also designed and developed the Smart Valve and Electric Actuator products for the DDG 1000 Class. Approximately 800 smart valves are installed on the three DDG 1000 ships in the fleet. Today, PV enjoys significant spare business to support the installed base on this futuristic ship class.
