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 caused by the inlet pressure rises above the force of the spring, the regulator opens until the spring force and inlet pressure are balanced again.
General-Purpose Diaphragm-Sensing Back-Pressure Regulators (KBP Series)
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.
Features
- Self-venting
- Convoluted, non-perforated diaphragm
- Metal-to-metal diaphragm seal
- Low internal volume
- Two-piece cap design provides linear load on the seal
High-Flow, High-Sensitivity Diaphragm-Sensing Back-Pressure Regulators
(KFB Series)
The KFB series regulator is designed to maintain back-pressure control in high-flow applications.
Features
- Large-diameter convoluted, non-perforated diaphragm for increased pressure sensitivity
- Metal-to-metal diaphragm seal
Compact Piston-Sensing Back-Pressure Regulators (KCB Series)
The KCB series provides high sensitivity back-pressure control of sampling conditioning systems. It is ideally suited for use in portable or laboratory analytical systems as well as being embedded in the instrument bays of OEM equipment or sampling cabinets.
Features
- Low internal volume
- Fully contained piston
- Excellent flow characteristics
- ANSI/ISA 76.00.02-compliant modular platform component (MPC) configuration available
Medium- to High-Pressure Piston-Sensing Back-Pressure Regulators
(KPB Series)
The KPB series provides back-pressure control in gas or liquid applications. This compact and lightweight regulator provides an ideal pressure-control solution within high-density compact OEM equipment, as well as other applications.
Features
- Integral high-pressure over-range protection
- Lightweight, compact design
High-Pressure Piston-Sensing Back-Pressure Regulators (KHB Series)
The KHB series provides control of back pressures and high sensitivity across the control range.
Features
- Integral high-pressure over-range protection
- Lightweight, compact design
