Gas Detector

Gas Detector Analyzer. A device which detects the presence of various gases within an area, and identifies them. These devices are used as part of a system to warn about gases which might be harmful to humans or animals. Gas detectors can be used to detect the presence of combustible, toxic, or specific gases.

  • SPEC #: 17723
  • Code: 17-20-03

Gas Manifolds

Gas Manifold: A chamber having several outlets through which gas is distributed or gathered. They range from simple supply chambers with several outlets to multi chambered flow control units including integral valves and interfaces to electronic networks.

  • SPEC #: 18468
  • Code: 18-41-18

Gas Poly

Gas Poly Piping. This polyethylene pipe is commonly called gas poly piping because of its nearly exclusive use by the natural gas industry for its distribution lines. This is due to several of its characteristics. It has excellent diffusion resistance. It can be installed with bends over uneven terrain in continuous lengths without additional welds or fittings. It is extremely resistant to scale build up and is impervious to most aggressive chemicals and corrosive elements. Its exceptionally smooth inner surface offers minimal resistance to flow over the life of the pipe. This pipe can be joined by a several methods, but heat fusion is preferred. Polyethylene pipe can also be joined with mechanical and flanged connections.

  • SPEC #: 18408
  • Code: 18-40-08

Gaskets

Piping Gaskets: Mechanical seals that fill the space between two pipes or fittings, and prevent leakage between them while under compression. Gaskets fill the irregularities between mating surfaces. Pipe gaskets are commonly manufactured from sheet materials, such as gasket paper, rubber, silicone, metal, cork, felt, neoprene, fiberglass, or plastic.

  • SPEC #: 18458
  • Code: 18-41-08

Gate

Automated Gate Valve: The same as a manual gate valve (see above), except the valve mechanism is moved by an electric, pneumatic, or hydraulic motor which is controlled by a remote switch or remotely generated electronic signal.

  • SPEC #: 17910

Gate

Manual Gate Valve: A valve that is opened by lifting a gate out of the path of the fluid. The sealing surfaces between the gate and the seats are flat. The gate faces can form a wedge or they can be parallel. Gate valves are designed to be fully opened or closed. When fully open, a gate valve presents no obstruction in the flow path, resulting in very low friction loss.

  • SPEC #: 17810

Gauge

Pressure Gauge: A device that measures pressure or vacuum. There are many types of pressure gauges operating upon several different physical principles, depending upon the environment and the level of pressure being measured. All function by sensing the pressure level and converting this information by either analog or digital means into a visual readout.

  • SPEC #: 17110
  • Code: 17-01-01

Gauge

Temperature Gauge: A device used to indicate the temperature of an item being monitored. The display can be an analog dial or a digital readout. Common methods of measuring temperature include bimetallic strip (bending of which increases with temperature) and the thermocouple which produces an electronic voltage that depends on the temperature.

  • SPEC #: 17210
  • Code: 17-02-01

Gauge

Mechanical Scale. Any of several mechanical devices that measure the weight of an object. The two most common types are spring scales and balances. A balance measures the weight of an object by comparing it to standardized weights. In compares the weight of the object placed in a pan on one end of the balance with standard weights placed in a pan on the other end. A spring weighing scale measures the forces necessary to stretch or compress a spring and convert this displacement to weight on an analog indicator.

  • SPEC #: 17310
  • Code: 17-03-01

Gauge for Chemical Process

Chemical Process Pressure Gauge. These gauges operate like all other pressure gauges. They sense the pressure level, and use that input to operate a readout.The characteristic that differentiates them from other gauges is the requirement to operate in processing systems that handle chemicals such as, hydrocarbons, petrochemicals, solvents, organic and inorganic acids, halogens, salts, caustics, etc. Many of these devices are designed to handle a broad range of chemicals, but must be selected for the specific process.

  • Code: 17-01-01 CP

Gauge for Chilled Water/Glycol

Chilled Water/Glycol Pressure Gauge. These gauges operate like all other pressure gauges. They sense the pressure level, and use that input to operate a readout.The characteristic that differentiates them from other pressure gauges is the requirement to operate in chilled water air conditioning systems that must cool below the freezing temperature of water. The gauge components that interface with the water/glycol media are usually made of copper.

  • Code: 17-01-01 CW

Gauge for Clean Air/Gas

Clean Air/Gas Pressure Gauge: These gauges operate like all other pressure gauges. They sense the pressure level, and use that input to operate a readout. The characteristic that differentiates them from other gauges is the requirement that the piping components of the gauges be made of a material like ABS or stainless steel, that will not break or chip from decompressing air, and that will withstand temperature swings of 30° F and pressures up to 140 psi

  • Code: 17-01-01 CA

Gauge for Instrument Air

Instrument Air Pressure Gauge. These gauges operate like all other pressure gauges. They sense the pressure level, and use that input to operate a readout.The characteristic that differentiates them from other transmitters is the requirement that they operate in an instrument air environment with pressures from 90 to 150 PSI

  • Code: 17-01-01 IA

Gauge for Sanitary Process

Sanitary Pressure Gauge. These gauges operate like all other pressure gauges. They sense the pressure level, and use that input to operate a readout.The characteristic that differentiates them from other pressure gauges is the requirement for extreme levels of cleanliness. They require special materials and have stringent cleaning requirements. Costly corrosion-resistant materials and special finishes are required for product contact areas, which must be cleanable and smoothly polished.

  • Code: 17-01-01 SP

Gear

Gear Positive Displacement Pumps. These pumps are fixed displacement, meaning they pump a constant amount of fluid for each revolution. They are one of the most commonly used pumps for hydraulic fluid power applications. There are two main variations: external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gear. As the gears rotate they separate on the intake side of the pump, creating a void and suction which is filled by fluid. The gears move the fluid to the discharge side of the pump, where the meshing of the gears displaces the fluid.
