Valcor Debuts New Quick Disconnect Couplings

Posted on Sep 25, 2019 in News & Events |

Published on: September 26, 2019 By: Valcor Aerospace Valcor Engineering Corporation, a designer and manufacturer of fluid control components and subsystems, clutches, brakes & OBIGGS systems, is proud to introduce a new product line capability: Quick Disconnect (QD) couplings. Quick Disconnect couplings are designed for demanding aerospace applications, with high pressure, high vibration, and large temperature extremes.These couplings are lightweight, have a large flow capacity, and minimal liquid loss during the unmating process. Valcor’s QDs are custom designed for specific applications. Therefore, material selection and line sizes can vary. Current QD designs are non-locking type, that require contact to maintain the couplings in the open position. Upon pulling the QD apart, each end closes and maintains the gas/liquid on each side of the fitting. They are capable of meeting low leakage requirements in high vibration environments. Current designs use tube stubs at the inlets and outlets for welding capabilities, with a 4-bolt flange. Valcor can also provide standard male AN fittings. “The addition of Quick Disconnects complements Valcor’s already comprehensive portfolio of fluid controls, which includes solenoid, service, and pneumatically-actuated valves, as well as regulators, tanks, and accumulators,” stated Larry Wismer, Senior Director of Sales & Marketing. “We provide our customers a one-stop shop for complete propellant systems.” About Valcor Valcor Engineering Corporation (www.valcor.com), founded in 1951, designs and manufactures solenoid valves and other fluid control components, as well as subsystems, clutches, brakes and OBIGGS systems in critical applications in the aerospace, nuclear, light industrial and scientific industries. Headquartered in Springfield, New Jersey, Valcor’s world-class staff of engineers, designers, and technical support personnel utilize fully equipped, modern test facilities to test the most precise and exacting standards. With a library of more than 18,000 designs, Valcor’s design team can modify existing technology to suit practically every hard to handle application. Valcor specializes in custom applications and can create an entirely new product to meet your...

White Paper: Comparison of Surge Pressure Mitigation Devices For Use in Propellant Feedlines During a Priming Event

Posted on Aug 8, 2019 in Events, Home Page, News & Events, White Papers |

Published on: August 27, 2019 By: Valcor Aerospace Comparison of Surge Pressure Mitigation Devices For Use in Propellant Feedlines During A Priming Event Vitor Cardoso 1 , Richard Kelly 2 , Yuri Gerasimov 3 Valcor Engineering Corporation, Springfield, NJ, 07081 Abstract The priming of a liquid propellant feed system can create surge pressures that can be damaging to the system. In the past, spacecraft have used flow restrictions such as orifices and venturis. The addition of such restrictions can cause significant pressure loss during thruster firings. This paper will discuss a new approach, which will be to install a flow limiter in the propellant line. Such a device would sense an abnormally high flow, and close so that the orifice size is reduced. This would limit the flow velocity, thus reducing the pressure surge. It would then return to its full open position during nominal flow, thus not producing any excess pressure drop during normal operation. This paper presents a trade study that compares four devices: an orifice, a venturi, a flow fuse, and a flow fuse with a dashpot (slow closing). It will be shown that the use of a flow fuse with a dashpot is the best option. Introduction High pressure spikes typically occur within propellant feedlines during a priming event1. Such an event occurs when a pyro valve, or latch valve opens, allowing liquid propellant to fill the downstream lines, which are at vacuum conditions. These spikes are the result of high velocity propellant flowing into a dead-ended line (closed valve). The impact of the column of liquid propellant hitting the closed valve creates a compression wave, also referred to as “Water Hammer”. This priming event is a well known phenomenon that has been much studied and analyzed. Pressure spikes may lead to detonation of the propellant. As a rule of thumb, pressure spikes should not exceed the proof pressure rating of both the pressurization lines and the flow control components. A possible solution is to install a fixed flow restriction in the line, which will decrease the liquid impact velocity, thus reducing the water hammer. The drawback to this approach is that the system will suffer from a pressure loss during normal flow usage. This paper presents a trade study of four devices: an orifice, a venturi, a flow fuse, and a flow fuse with a dashpot (slow closing). A flow fuse will sense an abnormally high flow, and close a poppet so that the orifice size is reduced. This would limit the flow velocity, thus reducing the pressure surge. The poppet would then return to its full open position during nominal flow, thus not producing any excess pressure drop during normal operation. A literature...

The Artemis Program & Valcor

Posted on Jul 12, 2019 in Events, News & Events |

Published on: July 12, 2019 By: Valcor Aerospace The latest updates on the Artemis-1 include a nice mention of Valcor and our Tank Pressurization Assemblies: “The pressurization / repressurization system within the Core Stage MPS is based on the same concepts as the Space Shuttle MPS that the RS-25 engines flew with Shuttle, but the implementation is significantly different from Shuttle. ‘We redesigned that whole system, so it’s not very orbiter-like,’ John Shannon, Boeing’s Vice President and Program Manager for SLS, noted in a recent interview. ‘We had those little pop-up valves before (Shuttle), now we have these tank pressurization assemblies that Valcor (Valcor Engineering Corporation) makes for us, much more robust.'” The full article can be found here Artemis 1, formerly Exploration Mission-1, will be the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida. The first in a series of increasingly complex missions, Artemis 1 will be an uncrewed flight test that will provide a foundation for human deep space exploration, and demonstrate NASA’s commitment and capability to extend human existence to the Moon and beyond.
