Swagelok® Back-Pressure, Spring-Loaded Regulators

 

back pressure spring loaded regulatorBack-pressure spring-loaded regulators are designed to maintain back-pressure control in analytical or process systems upstream of the regulator, high-flow applications, portable or laboratory analytical systems, gas or liquid applications, and high-sensitivity conditions. They are available in various styles to adapt to any setting or requirement. Their features make possible minimal leakage potential, low internal volume,  lightweight or compact designs, panel-mounting, and more.
