Valcor Engineering Corporation, a world-class designer and manufacturer of custom precision fluid controls, motion controls, and turnkey systems for space, aircraft, nuclear, and scientific/industrial customers, is proud to offer custom parallel pressure regulators.

Program Managers of Aerospace propulsion systems are typically challenged with minimizing the development costs of their programs. As program requirements are firmed up, system design engineers probe the industry to ascertain the availability of components that can meet the system requirements. One of the most complex and costly of these propulsion system components is the mechanical pressure regulator (PR). It is usually a challenge to find PRs that can service the inlet pressures, outlet pressures and flow rates of newly developed systems. To that end, a significant benefit to system designers is to have the ability to utilize existing PRs in new propulsion systems.

Using multiple PRs can potentially solve this problem, but historically, parallel PRs (and other mechanical valves) have demonstrated harmful instabilities when plumbed in parallel, and therefore, this arrangement has always been viewed as undesirable.

Valcor has helped several customers meet higher flow demanding applications with dual/parallel PR sets. Valcor’s PRs utilize technologies that produce fast responding and stable PRs. They have tested several different size PRs (with large variations in inlet pressure, outlet pressure and flow rates) in dual/parallel arrangements. These tests have demonstrated increased flow without any dynamic instability.

Valcor has tested 3 different dual parallel pressure regulator arrangements:

1) 3,600 psig GN2 (max inlet) and 160 SCFM.

2) 5,000 psig GN2 (max inlet) and 0.5 #/sec

3) 4,500 psig GHe (max inlet) and 36 SCFM

“The test results from a system of two identical pressure regulators, operated in parallel, without any adverse interactions are a testament to the unique design features and robust construction of the Valcor pressure regulators,” stated Paul Meyers, Aerospace Sales & Marketing Director.
