Swagelok® Back-Pressure Regulators
Back-pressure regulators control inlet pressure by balancing an adjustable spring force against the force of the inlet pressure. The spring force is adjusted by turning the stem/handle, which sets the desired inlet pressure. When the force rises above the force of the spring, the regulator opens until the spring force and inlet pressure are balanced again.

 KBP Series General-Purpose Diaphragm-Sensing Back-Pressure Regulators
The KBP series is a high-sensitivity, general-purpose regulator designed to control back-pressure levels in analytical or process systems upstream of the regulator. The convoluted diaphragm provides excellent sensitivity and set-point repeatability. The metal-to-metal diaphragm seal minimizes the potential for leakage.
