NUMATICS SANDWICH REGULATOR
Frequently asked questions
Common questions about NUMATICS SANDWICH REGULATOR from 3G Electric.
What is a Numatics sandwich regulator and how does it differ from a standard inline regulator?
A Numatics sandwich regulator is designed to mount directly between a valve manifold and an actuator, using the same mounting interface as the valve. This eliminates the need for separate piping and fittings, reducing potential leak points and saving space. Unlike a standard inline regulator that is installed in the air line, a sandwich regulator provides pressure control at the individual valve station, allowing different pressures for different actuators on the same manifold. It is part of a modular system where components stack together. The regulator is typically used in pneumatic circuits where precise, localized pressure adjustment is required. Installation involves removing the valve, placing the regulator between the manifold and valve, and reattaching the valve with longer mounting screws. This design simplifies maintenance and modification of pneumatic systems.
Which Numatics valve series are compatible with the sandwich regulators supplied by 3G Electric?
3G Electric supplies Numatics sandwich regulators for several valve series, including Mark 15, Mark 55, and others. Compatibility is determined by the mounting interface and port configuration. For example, part numbers starting with 152 and 153 are typically for Mark 15 series, while those starting with 554 are for Mark 55 series. It is essential to match the regulator to the specific valve series and manifold type. The product listings include manufacturer part numbers and descriptions that indicate the intended series. If you are unsure, provide the valve series and manifold model, and 3G Electric can confirm the correct regulator. Using an incompatible regulator may result in leaks or improper mounting. Always refer to the original equipment specifications or consult 3G Electric for assistance.
What pressure ranges are available for Numatics sandwich regulators?
Numatics sandwich regulators are available with adjustable pressure ranges typically from 5 psig to 130 psig, depending on the model. Some models offer a range of 5 to 60 psig, while others cover 10 to 130 psig. The maximum supply pressure and regulation range are specified for each part number. For example, the 809FN1 provides regulation from 5 to 60 psig, while the 809FN2 offers 10 to 130 psig. It is important to select a regulator whose range encompasses the desired operating pressure. Operating a regulator near the extremes of its range may affect performance. The regulators are designed for compressed air service and should not be used with other gases unless specifically rated. Always verify the pressure rating against your system requirements.
Can Numatics sandwich regulators be used in applications requiring relieving or non-relieving operation?
Yes, Numatics sandwich regulators are available in both relieving and non-relieving configurations. A relieving regulator vents excess downstream pressure when the set pressure is reduced, which is useful in applications where trapped pressure could be hazardous or affect actuator performance. Non-relieving regulators do not vent downstream pressure and are used when venting is not desired or when the system includes separate exhaust valves. The model number typically indicates the type; for example, part numbers with an 'R' in a specific position may denote relieving. It is important to select the correct type for your application. If you are unsure, consult the technical specifications or contact 3G Electric for guidance. Using the wrong type can lead to performance issues or safety concerns.
What materials of construction are used in Numatics sandwich regulators?
Numatics sandwich regulators typically feature bodies made from aluminum or zinc die-cast alloys, with internal components such as springs, diaphragms, and seals selected for compatibility with compressed air. Seals are commonly nitrile (Buna-N) or fluorocarbon (Viton) for higher temperature or chemical resistance. The adjustment mechanism may include a thermoplastic or metal knob, or a screw adjustment. These materials are chosen for durability and resistance to corrosion in typical industrial environments. The regulators are not intended for use with corrosive gases or liquids unless specifically rated. For applications with unusual media or extreme temperatures, consult the specifications or contact 3G Electric to discuss suitable options. Proper filtration and drying of the compressed air supply will extend the service life of the regulator.
How does 3G Electric support the Numatics sandwich regulator line for international customers?
3G Electric supplies Numatics sandwich regulators to customers worldwide, with logistics coordination and export documentation. The company maintains inventory of common part numbers and can source less common configurations. Technical support is available to help match the correct regulator to your valve series and pressure requirements. 3G Electric can provide datasheets, dimensional drawings, and installation guidance.
