Fluid and motion controls manufacturer Valcor Engineering Corporation (Valcor) has released its new whitepaper entitled, ‘Cryogenic Launch Vehicle Valves’.

Focusing on cryogenic rocket propellants, the paper outlines the challenges involved in designing critical fluid control systems for space launch vehicles (LVs). 

Due to the highly turbulent nature of flight, LVs experience extreme vibrations and shocks during payload delivery. 

This implies very specific testing procedures must be undertaken to ensure that components such as valves can handle the rigorous demands of space flight. 

Commenting on the whitepaper, Larry Wismer, Senior Director, Sales & Marketing, said, “Valcor has the flight-proven capability to design and manufacture a wide range of fluid components and systems, meeting the demanding performance and environmental challenges presented by the extreme cryogenic temperatures found in today’s space applications, including launch vehicles for earth orbiting satellites and spacecraft for deep space exploration.” 

Valcor’s whitepaper also discusses the company’s specialisation efforts involved in developing pilot-operated valves capable of achieving high flows in a compact, lightweight design, in addition to handling complex issues relating to different expansion rates of the valve’s materials. 

It also revealed plans by the company to propose a custom-designed manifold that incorporates ‘most, if not all’ of the fluid control components needed for specific applications. 

The manifolds are indicated by Valcor to provide a modular approach, reducing the need to include a complex assembly of individual components. 

Release of the new whitepaper comes around 18 months after a previous related publication, The Cold Hard Facts of Cryogenic Solenoid Valve Design, which examined Valcor’s cryogenic solenoid valves and its efforts to control cryogenic gases.
