Pressure & Temperature Controls |
|
|
Armstrong pressure-reducing valves (PRVs) and temperature regulators help you manage steam, air and liquid systems safely and efficiently. And they ensure uninterrupted productivity by maintaining constant pressure or temperature for process control.
Steam, liquids and gases usually flow at high pressure to the points of use. At these points, a pressure-reducing valve lowers the pressure for safety and efficiency, and to match the requirements of the application. There are three types of PRVs:
|
|
|
|
|
| The simplest of PRVs, the direct-acting type, operates with either a flat diaphragm or convoluted bellows. Since it is self-contained, it does not need an external sensing line downstream to operate. It is the smallest and most economical of the three types and is designed for low to moderate flows. Accuracy of direct-acting PRVs is typically ± 10% of the downstream set point. |
| |

An industrial-grade valve for water systems, the GD-24 is lightweight, compact and economical. The valve comes with screwed connections and will mount in any position. It requires no external sensing lines, and its bronze body and high-temperature diaphragm are suitable for hot or cold water service. The valve, seat and diaphragm are renewable in-line. The GD-24 has an external adjusting screw with lock and is available in six sizes, 1/2" through 2" (15–50 mm). |
The GD-200/200H valves offer high capacity and highly accurate control, with a large, cupped diaphragm for a long stroke. Compact and rugged, the GD-200's composition valve and bronze metal seat mean high performance over a longer service life. Well suited to non-viscous liquid pressure reduction, the valve is widely applied in domestic water applications, construction equipment, irrigation, tank-car loading, and industrial or commercial air conditioning. Upstream variations do not affect the balanced pressure valve, and the composition disc ensures tight shutoff. The turndown ratio is 10:1, and sizes range from 2" through 6" (15–50 mm). |

|
Internally Piloted Piston-Operated PRV |
|
| This type of PRV incorporates two valves-a pilot and main valve-in one unit. The pilot valve has a design similar to that of the direct-acting valve. The discharge from the pilot valve acts on top of a piston, which opens the main valve. This design makes use of inlet pressure in opening a large main valve than could otherwise be opened directly. As a result, there is greater capacity per line size and greater accuracy (± 5%) than with the direct-acting valve. As with direct-acting valves, the pressure is sensed internally, eliminating the need for an external sensing line. |
| |
GP-1000 Internally Piloted Pressure Reducing Valves
For Steam, Air, and Non-Corrosive Gases
|
The GP-1000 Series valves are pilot-controlled for accurate regulation of pressure under widely ranging flow. The internal-pilot design eliminates external components and piping.
Internally piloted GP Series valves are capable of larger capacity and greater accuracy than direct-acting valves. Internally piloted GP Series valves are rated for dead-end service and have a 20:1 turn down ratio and an accuracy of ± 5% of set point.
Completely supported by piping, lightweight GP Series valves install easily with NPT or flanged connections. A stainless steel diaphragm, hardened stainless steel working parts and integral removable strainer team up to provide higher performance over a long, trouble-free service life.
Valves are equipped with a caged main valve assembly (separate shutoff surfaces and flow-control ports), piston valve rings for longer life, and an external adjusting screw with locking nut and cover. All working parts are renewable in-line. For air service, a Teflon® seat ensures tight shutoff.
|
| |
|
Externally Piloted Diaphragm-Operated PRV |
|
| In this type, double diaphragms replace the piston operator of the internally piloted design. This increased diaphragm area can open a large main valve, allowing a greater capacity per line size than the internally piloted valve. In addition, the diaphragms are more sensitive to pressure changes, and that means accuracy of ± 1%. This greater accuracy is due to the location, external to the valve, of the sensing line, where there is less turbulence. This valve also offers the flexibility to use different types of pilot valves (i.e., pressure, temperature, air-loaded, solenoid or combinations). |

DS Series In-Line Separators DS-1/DS-2 |
|
| |
 DS-1/DS-2 In-Line Separators
|
|
Condensate in steam and air piping reduces thermal efficiency, causes water hammer, corrodes equipment such as valves and pipes, and causes other problems.
n-line (drain) separators DS-1 and DS-2 separate condensate efficiently by using the centrifugal force of steam or air created by introducing it into a specifically shaped path. Because of the simple structure of the drain separators, pressure loss is minimized, enabling clean, dry steam or air to be fed to equipment. |

The major cause of flooded heat exchangers is a lack of sufficient pressure differential across the steam trap under modulated steam conditions. With Armstrong's Posi-Pressure Control System, there is always a minimum preset differential pressure between the heat exchanger and the condensate-return system. Even if the pressure in the condensate return changes, the Posi-Pressure Controller automatically adjusts to maintain the preset differential. |
