Rock-Solid Solutions

Our company takes its name from a landmark located in Huntington Bay along the north shore of Long Island, New York. Just as the original rock withstood use as a target by British warships during the American Revolution and War of 1812, Target Rock products today perform in the toughest of conditions. 

50+ Years of Experience

Founded in 1951 to meet the special severe service valve requirements of the United States Nuclear Navy, Target Rock is today the premier supplier of highly engineered, valves and related products to both the U.S. Navy nuclear fleet and the global nuclear power generation industry. The first Target Rock valves were installed on the U.S.S. Nautilus, the U.S. Navy’s first nuclear powered submarine.

Target Rock valves continue to be the valve of choice for the U.S. Navy and they are installed on nuclear powered submarines and aircraft carriers commissioned by the United States. Since those early days, Target Rock has expanded to be the leading designer of critical solenoid valves for nuclear power reactors. Target Rock was also one of the first recipients of the ASME “N” stamp in the early 1970s. With over 6,000 valves installed in nuclear safety-related applications worldwide, Target Rock has the proven products and experience to handle the nuclear power industry’s most difficult applications.

Testing Capabilities

Development and Qualification Testing

Target Rock has designed, engineered and constructed an extensive array of test facilities to support the design, development and qualification testing of its products. All of Target Rock’s flow test facilities are supported by complete instrumentation services for measuring and recording pressures, temperatures, flows, noise levels, accelerations, displacements, forces and strains.

High Pressure Steam Testing

Two high pressure (2700 psi) boilers, with a steam generating capacity of 10,000 #/hr., supply four high pressure, stainless steel accumulators with a total capacity of 85 cu. ft. The accumulators supply two 4” and one 6” 2500# test section inlet flanges with the test section discharge piping sized at 10”. This unique facility may be used to achieve extremely high steam flow rates for seat leakage and set point certification testing or may be used for long duration, endurance type steam tests within the generating capacity of the boilers.

Pressurized High Temperature Water Testing

Four closed-loop, high temperature-pressurized water facilities constructed of stainless steel and rated at 3,000 psi @ 680°F can provide continuous flow rates of up to 300 GPM across the test sections. Higher flow tests may be conducted by injecting steam over pressurized hot water using a 65 cu. ft., 3,000 psi stainless steel accumulator.

Cold Water Flow Facilities

Various closed-loop ambient temperature water flow test facilities are available which can produce a wide range of flow rates and pressure drops. One such loop uses a 600 HP diesel to power a four stage centrifugal pump which delivers flow rates up to 1,000 GPM and differential pressures to 1,100 psid.

High Pressure Air

Two four stage compressors with a combined capacity of 40 CFM supply a bank of high pressure air receivers with a total storage capacity of 72 cu. ft. Extremely high flow rates can be achieved when this facility is used in a blowdown mode in conjunction with a 65 cu. ft. accumulator.
