Fill and Drain (Service) Valves

Product catalog summary

Description and Features
Valcor Aerospace's Fill & Drain (Service) Valves are designed for use in propellant and pressurant systems, particularly within Reaction Control Systems (RCS) and Attitude Control Systems (ACS). These valves are suitable for environments with high vibration, extreme temperatures, and corrosive fluids. They are also applicable in aircraft pneumatic pressure vessels, hydraulic systems, and waveguide pressurization systems. Key features include extensive material options for the body and seal, tight internal and external leakage rates (1 x 10^-6 sccs), triple redundant sealing, and options for flange mounting or tube ends. The valves are capable of high operational cycles and are compatible with various liquids and propellants, including Hydrazine, NTO, MMH, ammonia, and pressurants like GHe and GN2.

Applications
The valves are used in aerospace applications where reliability and durability are critical. They are designed to handle high pressures and are available in configurations that support different mounting and connection options, such as flange mounting and tube ends for welding.

Specifications
The document lists various Valcor part numbers with their corresponding inlet and outlet specifications, body materials, compatible media, and operating pressures. For example, part number V24000-01 features a 10-32 UNJF flange with an aluminum body, suitable for GN2 and GHe at 1,100 psi. Another example, V24000-04, uses a 1/4-28 UNJF tube with an Inco 625 body, capable of handling GN2 and GHe at 10,000 psi.

Summary of Key Data
The valves are available in a range of materials including aluminum, titanium, and Inco 625, with operating pressures ranging from 300 psi to 10,000 psi. They are compatible with a variety of media, including GN2, GHe, Hydrazine, NTO, and ammonia, among others. The document provides a comprehensive list of part numbers, each with specific configurations and pressure ratings, ensuring that a suitable valve can be selected for a wide range of aerospace applications.

Catalog excerpts

Valcor Aerospace Valcor Fill & Drain (Service) Valves are metal-to-metal seat valves that maintain extremely low internal and external leakages (1x10A-6 sccs GHe), yet are capable of very high operational cycles (over 100 open/close cycles). Our Fill & Drain Valves are compatible with liquids and propellants (Hydrazine, NTO, MMH, etc.), ammonia, and pressurants (GHe and GN2). Options such as flange mounting, tube ends (for welding), color coded covers and bodies, and covers with lanyards are also available. These valves have applications in propellant and pressurant systems as part of th reaction control systems (RCS) and Attitude Control Systems (ACS), where high vibration, large temperature extremes and corrosive fluids are present. They are also found in aircraft pneumatic pressure vessels, hydraulic systems, and waveguide pressurization systems. Extensive material (body and seal) options Tight external leakage (1 x 10-6 sccs) Tight internal leakage (1 x 10-6 sccs) Triple redundant sealing Flange mounting or tube ends available High capacity and high pressure designs available © 2014 VALCOR ENGINEERING CORPORATION
