The Ashcroft GC35 is a compact indicating transducer with analog scaling and switch outputs. Incorporating field-proven thin film sensor, this model can monitor a wide variety of applications. An ideal choice for optimizing instrument costs.

The new Ashcroft Model GC52 is uniquely compact wetwet differential pressure transmitter, ideal for flow and tank level applications where reliable, low dP measurements are required.

Equipped with the patented SiGlas 316 Stainless Steel isolated sensor, the GC52 can monitor a wide variety of wet or dry media.

Available in unidirectional ranges from 0-4 to 0-400 in.W.C and bidirectional ranges up to 200 in.W.C., the GC52 operates on line (static) pressures up to 300 psi. A rugged aluminum NEMA 4X IP65 enclosure measures only 2.56 inches in diameter and incorporates a backlit LCD display for local reading. The output is a two-wire configurable 4-20 mA signal that can be adjusted to re-range the transmitter or "tare" unwanted fluid head preloads.

In addition, this instrument offers flow measurementsquare root extraction, where the momentary flow rate can be displayed and analog signal can be output.

Jordan Valve is a leading manufacturer of high quality products for the U.S. and international markets. Founded in the late 1940's with just one product - a small mixing valve - Jordan Valve has evolved into a complete line of pressure and temperature regulators, pneumatic and electric control valves and sanitary valves.

The cornerstone of the Jordan Valve product line is the sliding gate seat. Jordan is the originator of the sliding gate design which was first developed in 1947 by William Jordan. The sliding gate is a unique and superior seat design that provides many advantages over traditionally designed pressure and temperature regulators and control valves.

Straight-Through Flow

The disc is moved across the surface of the plate by the disc pin. When throttled open, the slots of the disc and plate align to allow the required flow through the seats. Since the flow path is straight through the slots, turbulence, noise, and wear are reduced. Another feature of this unique design is that the disc is supported from behind by the plate. This enables the seats to operate efficiently in the near closed position without being disturbed by the high, un-balanced forces a single seated globe valve would experience. This unique ability provides much higher rangeability than can be achieved with a globe style valve while maintaining tight shut-off. In conventional rising stem globe style valves.

The new Ashcroft Model GC51 is a uniquely compact pressure transmitter, ideal for monitoring pressures in process automation, hydraulic systems, compressors, pumps and in tank level applications where consistent, reliable pressure measurement is essential.

The GC51 is equipped with Ashcroft's field-proven thin film sensor and can monitor a wide variety of wet or dry media.

Available in ranges from 0-50 to 0-7500 psi and compound ranges up to -1550 psi, this versatile transmitter includes a min.max. hold feature to record high and low pressure events.

A rugged aluminum NEMA 4X IP 65 enclosure measures only 2.65 inches in diameter and incorporates a backlit LCD display for local reading.

The output is a two-wire configurable 4-20 mA signal that can be adjusted to re-range the transmitter or "tare" unwanted fluid head preloads.

A compound gauge is a device that can display both positive and negative (vacuum) pressures. You need to use a compound gauge when you are measuring a system that is exerting both positive and negative pressure on the gauge. Gauges are designed to measure specific types of pressure, so if you pick a simple pressure or vacuum gauge for a system that requires a compound gauge, the gauge will most likely be damaged. The exertion of negative pressure on a pressure gauge will cause damage, and likewise the exertion of positive pressure on a vacuum gauge will also damage the gauge.

Pressure gauges use pounds per square inch (psi) as the unit of measure. Vacuum gauges, on the other hand, measure force in units of inches of mercury (in.Hg). Both of these measurements will be displayed on the face of a compound gauge. The needle in a compound gauge will move clockwise when measuring positive pressure, and counterclockwise when measuring negative pressure.

To check if your gauge is operating properly remove the gauge from the line. Turning off your process is not sufficient because pressure may still be present. Once pressure has been removed from the line, a properly working gauge will read zero. If the gauge does not return to zero, then the gauge is likely damaged.

Did you know that a pressure snubber will protect pressure gauges from the harmful effects of vibrations generated in a pressurized system? The pressure snubber works by evening out the rate at which the fluid or gas being measured arrives. While the snubber does not alter the pressure of the process, it will lessen the pulsation on the line, thereby improving the consistency of the gauge reading, and extending the effective lifetime of that particular gauge.

Now you might be thinking to yourself, doesnt a fluid filled gauge achieve the same result? Well, yes it does. Most of the time you will need a snubber though, is after you have already installed a liquid filled gauge. In many intensely pressurized systems, you would start out by installing a liquid filled gauge to improve the readability of the gauge, while also offering it some protection. But some pressure systems are so intensive that you need to install a snubber in addition to the liquid filled gauge.

As with all pressure system components, the price of a snubber varies based on a number of factors. At the low end of the scale, are porous disc snubbers. These snubbers utilize a fixed mesh disc to provide steady gauge measurements. The price is heavily dependent upon the size, material, and pressure rating of the snubber. Higher end snubbers utilize a piston mechanism which can drive up the price. If you feel your system might be improved with a pressure snubber, make sure that you choose one suitable to the process in which it will be used. When you are selecting a snubber, be sure to check the pressure generated by your system, and then choose a snubber with an appropriate PSI range.

The A-Series stainless steel pressure switch is designed for tough OEM and industrial applications requiring a durable, high quality miniature switch. Choose from NEMA 4 watertight or NEMA 7 explosion proof enclosures.

The Hex monoweld is used on upstream offshoreonshore gas and oil production and initial processing installations. Typically used on single or dual gauge pressure or analyzer installations to minimize the size and weight of the pipe-valve assemblies used for primary andor secondary isolation, vent and calibration. Also used in downstream oil and gas refining and petrochemical production on welded, or flanged pipe processes, primary on gas applications or light end liquids.
