Clarke Valve & Curtiss-Wright Corp. First to Meet NAVSEA Spec. MIL-DTL-32632

Aircraft carrier

On July 25, 2019 the United States Naval Sea Systems Command (NAVSEA) published Detail Specification MIL-DTL-32632, which establishes the criteria for the design, materials, and functional capabilities of all “dilating disk” valves for flow control of Naval shipboard water, oil, and gas service. The specification was developed to explicitly classify low torque, hysteresis-free control valve designs consisting of three or more rotationally closing plate segments.

The Dilating Disk™ Valve, developed and manufactured by Clarke Valve in the USA and protected by nine worldwide patents, is currently the only control valve that meets all the specifications outlined by NAVSEA in MIL-DTL-32632. Clarke Valve has licensed this technology to Curtiss-Wright Corporation, a well-established valve solutions provider to the US Navy, and all valve products delivered to the US Navy appear under the Curtiss-Wright brand name through its Target Rock business unit located in East Farmingdale, New York.

“The release of this Detail Specification by NAVSEA aligns with the US Navy’s goals of reducing weight and increasing efficiency in their valve systems to meet Fleet Modernization goals,” said Kyle Daniels, President and CEO of Clarke Valve. “It is a great source of pride for Clarke Valve to be first in meeting the stringent requirements outlined by NAVSEA, and we are pleased to be working with an industry leader like Curtiss-Wright to fulfill the needs outlined in MIL-DTL-32632.”

“Curtiss-Wright is pleased to enhance its legacy of offering critical valve technology, further building upon our long-standing relationship with the US Navy and continuing our ongoing support of critical national defense platforms,” said Kevin Rayment, Senior Vice President and General Manager, Curtiss-Wright Industrial Division.
