Type 884 Extended Bonnet (14 in.) Globe Control Valve

DESCRIPTION

The U.S. Type 884 extended bonnet globe control valve is available in varying lengths for 1/4 in. through 1 in. line sizes. It is specifically designed for the control of extremely cold or hot fluids and gases. In cryogenic applications, the bonnet length serves to extend the packing area, as well as allow room for insulation around the body and bonnet. The design also facilitates cold box mounting. A casing flange is available as an option if sealing to the cold box is required. Other models are available to facilitate the removal of the inner valve and seat from outside the cold box (Type CBX). In hot applications, the extended bonnet allows the standard TFE packing to be isolated from high temperatures. The factory should be consulted when the service temperature exceeds 800° F (426° C).
NOTE: In all applications, the TFE ring packing should not be used when the temperature at the packing is below –120° F (–84° C) or above 350° F (176° C).

APPLICATIONS

The Type 884 valve is widely used in industrial applications, research, and process pilot plants for liquids and gases when temperatures are in the cryogenic range. The 14 in. (356 mm) bonnet normally performs well for temperatures down to – 450° F (–268° C) such as liquid C02, hydrogen, and nitrogen. Bonnet lengths up to 6 in. (1524 mm) can be supplied. Also available are extended bellows seal bonnets for applications where stem sealing is critical.

The heat reduction allows the standard CV ring packing to be used at higher process temperatures than could normally be tolerated with the standard valve.

APPLICATIONS

Type 973 valves are widely used in high-temperature applications where steam, hot water, hot hydraulic oil, or other fluids and gases must be controlled precisely at temperatures exceeding the limits of the standard finned bonnet valve. Follow the appropriate pressure and temperature rating of the body material and the packing and trim material.

Type 808 Bellows Sealed Global Control Valve

DESCRIPTION

The U.S. Type 808 bellows sealed globe control valve is especially suited to applications where the possibility of packing leakage cannot be tolerated. The bellows form a flexible static seal that is virtually leak-free, as long as the integrity of the bellows remains intact. The unit contains a set of backup packing that, in many cases, will allow the valve to continue in service until repairs can be made, should the bellows fail. The bellows are available in two pressure ranges:

  • The low-pressure bellows fits 1/4 in. (6.4 mm), 1/2 in. (12.7 mm),
    3/4 in. (19.1 mm) or 1 in. (25.4 mm) valves and is available in
    four materials.
  • The high-pressure bellows fits 1/2 in. (12.7 mm) through
    1 in. (25.4 mm) valves and is rated at 1500 psi for
    throttling applications.

NOTE: Consult the factory when using this bellows.

APPLICATIONS

The Type 808 valve is widely used in industrial applications, research, and process plants on liquids, gases, or steam. The statically sealed bonnet makes it especially suited to applications where expensive concentrates are controlled and cannot be allowed to leak. Other applications arise when fugitive emissions must be prevented or when sensitive flow streams must be isolated from the ambient atmosphere. This type of seal performs well in high vacuum service where standard packing is not desired.

Type 1118 Three-Way and Diverting Valve

DESCRIPTION

The U.S. Type 1118 three-way valve is available in either 3/4 in. (19.1 mm) or 1 in. (25.4 mm) sizes for modulating control of liquids,
gases, or steam in either mixing or diverting applications. The unit features one common port and two non-common ports. When used
in a diverting application, the common port is piped as the valve inlet with flow proportionally controlled through the two outlet ports. When used in a mixing application, the common port is piped as the outlet with incoming fluid entering the two non-common ports. In this application, the inlet pressure to the two inlets should be the same. Each inner valve within the unit is connected by a common stem and is stroked simultaneously by the actuator. This action causes one orifice to open as the other is closing. The Cv of each inner valve can be the same or of different value, depending on the requirements of the application.

APPLICATIONS

The Type 1118 three-way valve is used in mixing applications such as temperature control. By varying the position of the inner valve,
the percentage of fluid passing through each port can be controlled as it exits the common port. The same concept can be applied to the blending of various chemicals, dyes, additives, and other fluids or gases that must be proportionally mixed. The Type 1118 valve is also well suited to diverting applications such as flow or pressure control in hydraulic systems. In a hydraulic system, the fluid enters the common port of the valve with one of the non-common ports controlling the flow to a cylinder or a vessel. The unused fluid is re-circulated back to the sump through the other non-common port.

The unit features one common port and two non-common ports. When used in a diverting application, the common port is piped as the valve inlet with flow proportionally controlled through the two outlet ports. When used in a mixing application, the common port is piped as the outlet with incoming fluid entering the two non-common ports. In this application, the inlet pressure to the two inlets should be the same. Each inner valve within the unit is connected by a common stem and is stroked simultaneously by the actuator. This action causes one orifice to open as the other is closing. The Cv, as well as the characteristics, of each inner valve, can be the same or of different values, depending on the requirements of the application.

APPLICATIONS

The Type 564 valve is widely used in mixing applications such as temperature control; for example, when a cold fluid enters one of the non-common ports of the body and a hot fluid enters the other. By varying the position of the inner valve, the percentage of fluid passing through each inner valve can be controlled as it exits the common port. The same concept can be applied to the blending of various chemicals, dyes, additives, and other fluids or gases that must be proportionally mixed. The unit is also suited to diverting applications such as flow or pressure control in hydraulic systems. The hydraulic fluid enters the common port of the valve with one of the non-common ports controlling the flow to a cylinder or vessel with the unused fluid re-circulated back to the sump area through the other non-common port.
