The EL-PRESS series digital electronic Pressure Meters and Controllers have a well-proven compact thru-flow design and are available in pressure ranges from 2-100 mbar up to 8-400 bar, both in absolute and relative (gauge) pressure. A differential pressure transducer can also be supplied in the ranges of 2-100 mbar up to 0,3-15 bar. The pressure controller performs with high accuracy and repeatability and should be specified for forward or backward pressure control. Todays EL-PRESS series are equipped with a diaphragm type piezoresistive pressure sensor and a digital pc-board as standard and offer high accuracy, stability and reliability. The basic digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output, the instruments also offer analog I/O. As an option, an integrated interface board provides DeviceNet, PROFIBUS-DP, Modbus-RTU or
FLOW-BUS protocols.

The Type-700BP Back Pressure Regulator is a high flow, highly accurate pneumatic relief valve with an adjustable set point. It's primary function is to provide protection against over pressurization in the downstream portion of a pneumatic system. This precision unit is capable of handling flows up to 50 SCFM. A rolling diaphragm provides the sensitivity that causes the Type-700BP to vent to atmosphere in response to the slightest upstream changes.

The Type-9OOX l/P, E/P transducers are a series of compact electronic pressure regulators that convert an electrical signal (current or voltage) to a proportional pneumatic output. Utilizing internal solid-state feedback circuitry, the Type-9OOX provides precise, stable pressure outputs to final control elements. Immunity to the effects of vibration or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for use in demanding applications.
The heart of this unique technology is a bimorph piezo actuator that is encapsulated in a protective skin. This protective skin provides defense against the humidity and contaminants often found in process operating environments.

Beswick Engineering’s "PCFCD" Pressure Compensated Flow Control Valve was selected as the Best Product Winner, in the Motion Control category, of Design News magazine’s 2008 Golden Mousetrap Awards. This accolade was just announced to the public in the September 22nd, 2008 issue of Design News.
The PCFCD-1N1 is designed to maintain a constant flow rate, which the customer can adjust, regardless of upstream or downstream pressure variations. It works with both liquids (incompressible fluids) and gasses (compressible fluids) but is primarily intended for the control of liquids. The pressure regulation is accomplished with a low friction diaphragm mechanism. Beswick has applied for patent protection on this unique valve.
The PCFCD-1N1 sets an industry standard for miniaturization. It is lightweight….tipping the scales at only 48 grams. Customers will find it particularly useful when space, weight, and precise liquid flow control are critical.
The PCFCD-1N1 controls flow rates of 0 to 4.2 gallons per hour of Water (0 to 20 cubic feet/hour of Air). It is especially suited for the control of low flow rates. The maximum rated inlet supply pressure is 500 psig. Both the inlet and outlet ports are tapped 10-32. The valve body is both small and lightweight allowing for convenient in-line mounting without the need for a panel mount thread. The PCFCD-1N1 is currently available in brass. Buna-N is the standard seal material. Fluorocarbon (Vitonâ) is optional.

The Type-800 is a compact air regulator that supplies precise air pressure control for applications where space is limited. This high quality unit, available in five pressure ranges up to 100 psig (700 kPa), offers the same dependable performance as ControlAir's larger precision air pressure regulators. An oversized supply valve provides the Type 800 with significantly higher flow capacities than competitive units of similar size. The Type 800 is also available with a variety of convenient port sizes and mounting options. Corrosion resistant materials, lightweight construction and low cost, combine to make the Type 800 ideal for any application where space is at a premium.

PRD - Single-Stage Diaphragm Pressure Regulator
Description: The PRD-ANB-C-DEF regulator sets an industry standard for miniaturization as well as lightweight. It is an excellent choice for gas and pneumatic pressure regulation applications and is particularly useful when space and weight are critical. The PRD-ANB-C-DEF weighs approx. 25 grams in brass & stainless steel and about 15 grams in aluminum. The PRD-ANB-C-DEF non-relieving regulator controls output pressures from 0 to 30 psig and is especially suited to low pressure regulation such as ½ psig. Maximum inlet supply pressure is 500 psig. Both the inlet and outlet ports are tapped 10-32 UNF. Its lightweight design allows convenient in-line mounting however a 10-32 threaded panel mount option is also offered. Applications include hydrogen fuel cells, medical equipment, instruments, laboratory equipment, ink jet print engines, and semiconductor manufacturing equipment.
Material: Brass, aluminum, 303 & 316 stainless steel.

Description: The new PRD2 –ANB-C-DEF two-stage nonrelieving diaphragm regulator sets an industry standard for both miniaturization and light weight. It weighs approx. 50 grams in brass and stainless steel, and about 23 grams in aluminum. It accurately reduces high-pressure inputs (up to 500 psi) down to 0 to 20 psi (and is especially suited to low pressure regulation such as ½ psi.) with minimal droop or rise even with wide swings in inlet pressure. The Beswick two-stage diaphragm regulator is an excellent choice if the inlet pressure will decay over time such as with hydrogen storage tanks commonly used in hydrogen fuel cell applications. Both the inlet and outlet ports are tapped M3. Its lightweight design allows convenient in-line mounting however a 10-32 threaded panel mount option is also offered.
Beswick Engineering designs and manufactures high-performance miniature fluid power components, such as: fittings, valves, quick disconnects, pressure regulators/gauges, cylinders, filters, orifices, shock absorbers, pressure electric switches, tubing, etc. Applications include: medical and dental equipment, instruments, laboratory equipment, semiconductor manufacturing equipment, aerospace equipment, packaging machinery, industrial robots and many more.
