Regulators
A regulator is a device designed to automatically maintain an operating characteristic. Regulators monitor a set characteristic, measure the operating characteristic against the set value, and maintain operation at, or within range, of the desired value.

In pump and flow control applications, regulators are commonly designed to measure and control pressure. Pneumatic and hydraulic regulators are used for air pressure and liquid pressure, respectively.

As the regulator monitors fluid pressure in the system, an actuator opens or closes valves to increase or decrease internal pressure. The regular can also measure flow rate and ambient, and account for both when adjusting system pressure.

TYPE 10 Series Image
  • The exceptionally large capacity of this relief valve assures immediate response
  • Type 10 Regulator controls output pressure with an accuracy of 0.1%,
  • Particularly good from dead end to 20 cubic meters per hour
  • The standard Type 10 regulator has a locking nut
  • The unit may be installed in any position.
Industrial processes, inspection procedures, control and analytical instrumentation require precise regulation of air pressure in pipes and vessels. Maintaining constant pressures in these applications is usually complicated by the presence of numerous disturbances, such as changes in supply pressure, flow, and ambient temperature that tend to upset prevailing conditions. Bellofram Pressure Regulators provide accuracy, precision control, and maximum stability under the most adverse operating conditions.
TYPE 41 Series Image
  • Self-relieving of excess downstream pressure
  • Rugged, corrosion-resistant construction
  • Superior regulation characteristics
  • Excellent stability and repeatability
  • Low droop at high flow
The Type 41 regulators are designed for applications requiring high flow capacity, low droop, high accuracy, and fine adjustment sensitivity. The use of Bellofram’s rolling diaphragm provides greater sensitivity and improved accuracy. In addition, Type 41 regulators offer reduced over-all size and several mounting options, providing direct interchangeability with more expensive competitors’ units.
TYPE 91 Series Image
  • Designed for applications with limited space and for low flow or dead end service
  • Small package size and lightweight construction
  • Corrosion resistant anodized aluminum exterior
  • Excellent stability and repeatability
  • Self relieving
The Type 91 Subminiature Regulator is a compact, low-cost unit which operates in pressure ranges up to 100 PSI, with a maximum supply pressure of 250 PSI. It provides dependable reliability and accuracy for low flow or dead end applications, but is not designed for critical flow applications. The Type 91 subminiature regulator is available with a corrosion resistant anodized aluminum body and bonnet or with a brass body and bonnet. Both come standard with a fluorocarbon diaphragm.
TYPE 70 Series Image
• Buna-N and polyester rolling diaphragms are designed to give millions of cycles
• Construction can be disassembled and serviced without removal from air line
• Responds quickly to minute changes in upstream pressure
• High flow Capacity - Up to 50 SCFM (1400 LPM)
The Type 70 Back Pressure Regulator functions as a high flow, high precision pneumatic relief valve with an adjustable setpoint. The Type 70BP can be used in place of a standard relief valve to improve pressure control while maintaining protection against over pressurization, as in supply pressure lines to instruments and other control devices.
20000 Series Image
  • ˝” to 1 ˝” NPT or SAE Ports
  • Ideal for Oil Drilling Applications
  • High Sensitivity and High Flow Capacity
  • Failsafe Motor Control Options
  • Tolerates Contaminated Media
Barksdale's pressure regulators are sensitive pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. The regulated output pressure can be controlled either by the force of a spring, or a motor (hydraulic or pneumatic). Design features ensure excellent accuracy, repeatability and high flow coefficients. Designed to provide years of trouble-free operation and virtually zero leakage, the Shear-Seal® design uses fluid pressure to maintain a leak-free metal-to-metal seal that improves with use. The shearing action between the rotor & pressure seal continually laps the mating surfaces and prevents contaminates from lodging between the sealing surfaces. The result is a valve that doesn’t wear out – but wears in over time, providing you superior control consistently through the entire life of the product.
