Pressure valves gover the pressure within a hydraulic system. The types below are intended for the following purposes:
* Pressure limiting valve (safety valve):
Safeguarding the system against excessive pressure or for the limitation of working pressure.
* Sequence valves:
Generates a constant pressure difference between inlet and outlet of the flow.
Directly controlled valves feature a dampening device to ensure quiet operation, but they are also available without it if necessary for an application. There is also a version of the pressure limiting valve (Type MV.X), conforming the Pressure Equipment Directive 97/23 EC, which features a type approval and a CE-stamping, usually necessary when used as safety valves for accumulators.

The In-Line pre-set regulator must be mounted directly on the pneumatic tool or system in order to ensure correct pressure, so that possible pressure drops in hoses, tubes etc., do not influence the pressure on the tool or system it self.
The pre-set regulator supplies a constant, exact outlet pressure regardless of the inlet pressure. The pressure is factory-set and cannot be changed. This ensures that nobody can alter the specified pressure.

DOPAG material pressure regulators (MPR) reduce the pressure of the incoming material to the optimum operating pressure.
As well as accurately regulating material pressure, these valves will also compensate for pulsations that occur as a result of the reciprocating action of piston pumps.

Lee Company restrictors have become the accepted “standards” worldwide. Design engineers find their small size, light weight, and proven reliability are indispensable when the flow of fluids has to be controlled.
Our miniature precision flow restrictors are specified by manufacturers of aircraft hydraulic and fuel control systems, oil drilling equipment, missile controls, machine tools, and countless other products. Lee restrictors are a vital part of almost every military and commercial aircraft manufactured in the world. By employing already proven and qualified Lee restrictors in their designs, design engineers are using their own time and talents much more productively.
Lee offers a wide selection of single-stage or multi-stage orifices. Lee Jets, High Watt and Kilowatt Jets, and the Lee Microjet are all single orifice restrictors. Lee High Watt and Kilowatt Jets handle low Lohm rates (high flow rates) while higher Lohm rates (lower flow rates) are covered by Lee Jets.

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.

Especially suited for use with Airpot actuators and Airpel cylinders where low friction/low hysteresis, sensitive response, long life, clean operation, and extreme temperature are critical requirements. Offered in both compact and standard configurations for moderate and high flow, Airpot FFR systems are available with standard or precision regulators for precise control and sensitivity. Airpot FFR systems are composed of lightweight aluminum/resin hybrid material built into a compact and modular 40mm x 40mm envelope per component (compact series). Standard and Precision series (with increased low pressure sensitivity) regulators are available; all with hand adjustability and single push lock operation. The precision series offers a pressure range of 0.005 to 0.4 MPa and sensitivity within 0.1% of the full scale. Port connections are available with NPT or G metric threads. Each system is equipped with dual filtration modules that remove particles, dust, oil, moisture and mist down to 0.01 micron. This two stage filtration system is comprised of a 5 micron dust and moisture filter augmented by a 0.01 micron coalescing filter. The long life media transitions from a coarse outer surface to a fine interior structure to reduce clogging prolong life and prevent rust formation. All filters boast a standard corrosion resistant filter bowl guard, one quarter turn filter element removal and a unique O ring slip prevention design. FFR gauges offer highly visible color zone indicators, field adjustable limit marks, flat face design with a non- protruding (standard series, compact and high flow types) gauge embedded in the module made to JIS3 grade with either MPa or PSI readings.
