Swagelok® Back-Pressure, Dome-Loaded Regulators
Back-pressure regulators control inlet pressure by balancing the dome pressure against the force of the inlet pressure. When the inlet pressure rises above the dome pressure, the regulator opens until the dome pressure and inlet pressure are balanced again.
Swagelok® Back-Pressure, Spring-Loaded Regulators
Back-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.
Swagelok® Pressure-Reducing, Dome-Loaded Regulators

Pressure-reducing dome-loaded regulators deliver many options and features that include compact sizes, dome- and air-loaded styles, piston sensing, balanced designs, high-purity, high-flow, integral pilot-operated, and differential. They can be ordered as both venting and non-venting. Multiple gauge connection configurations are also available.
Swagelok® Pressure-Reducing, Spring-Loaded Regulators

Pressure-reducing spring-loaded regulators are available in numerous models to fulfill different needs. They are designed for use in applications requiring constant outlet pressure, gas or liquid applications, minimum droop in low-flow and low-pressure conditions, control for pressures up to 10000 psig (689 bar), high-purity or high-flow applications, compact settings, and more. Features include bottom mounting, self venting, tamper-free designs, panel-mounting, convoluted and non-perforated diaphragm, metal or polymer seats, and two-stage.
