Series 240 Control Valves are available in nominal sizes ranging from DN 15 to DN 300 (½" to 12") and up to a nominal pressure PN 40 (Class 300).
Control valves in the standard version are suitable for temperature ranges between -10 and 220 °C (15 and 430 °F). An insulating section allows the temperature range to be extended to -200 and 450 °C (-325 and 840 °F).
The plug stem is sealed either by a self-adjusting PTFE V-ring packing or an adjustable packing. To meet stricter emissions control requirements, a stainless steel bellows is used. The Type 3241 Control Valve can be equipped with a heating jacket that may also include the bellows.
Series 250 Control Valves are used when large nominal sizes and/or high pressures are involved in process engineering, power plant or supply engineering.
In addition to globe, three-way and angle valves, four-flanged valve bodies with bottom plug stem guides, and valves with axial multi-stage throttling plugs, customized valve constructions to meet customer specifications can be engineered as well.
The valves are manufactured in nominal sizes from DN 15 to DN 500 (½" to 16") and for nominal pressures between PN 16 and PN 400 (Class 150 to 2500).
The standard versions of these control valves are suitable for temperatures ranges between -10 and 220 °C (15 and 430 °F). This temperature range can, however, be extended by using an adjustable high-temperature packing to a temperature range between %u201310 and 350 °C (15 and 660 °F) and by using a bellows seal or an insulating section to a temperature range between %u2013200 and 500 °C (%u2013325 and 930 °F).
Series 280 Steam-converting Valves are used to reduce both the steam pressure and steam temperature to optimize plant operation and heat efficiency in process plants, for example, in refineries, food and beverage, tobacco or pulp and paper industries.
Steam-converting valves are based on Series 250 Valves fitted with a flow divider St III and an additional spray water connection. They are available in nominal sizes ranging from DN 50 to DN 400 (1" to 16"), with nominal pressures of PN 16 to PN 400 (Class 150 to 2500) and for temperatures up to 500 °C (930 °F).
The Type DUV-C3 Steam-converting Valve from Welland & Tuxhorn is designed for high-pressure ranges and can be engineered with varying inlet and outlet sizes. The inlet nominal sizes range from DN 80 to DN 500 and the outlet nominal sizes
from DN 100 to DN 1600. Large amounts of spray water can be injected thanks to the integrated atomizing steam cooler. The valve can be operated in a wide load range.

Brief introduction
BT-1000 was developed by Bettersize dedicated to determine the flowing properties of the ppowders. Whether flow or stay, powder is two-phase system. Intrinsic properties and collisions of particles will generate special flowing properties it is significant to study for powder processing, transport, packing, storage. This unit is characterized by multi-functions, easy operation, good repeatability, flexible test device to suit many standards. The success of the instrument provide a new measure for universal deployment of the powder integrative characteristics work.
It can test angle of repose, collapse angle, flat plate angle, dispersibility, bulk density and tap density, after that can obtain difference angle, compressibility, voidage, regularity & uniformity, also by Caar index user can get flowability index and jetting ability.
Standard test properties
1. Tap density: vibrate a container loaded with powder to fill up air gap among particles thus make powder more compact, in which means flowability and voidage are obtained. (Note: tap density of metallic powders are measured in conformity with related standard.)
2. Loose density: the density of powders, which fill a special container naturally. It is important for storage container and design of packing bags. (Note: loose densities of metallic powders are measured in conformity with related standard.)

Demand continues to mount for improved comfort conditioning combined with lower operating costs. New architectural designs have created real problems for contractors and engineers to maintain humidity control at reduced loads, and to control load variations. Refrigeration and air conditioning systems are usually designed to provide a given capacity at maximum conditions. These operate with little fluctuation throughout a narrow load range. However, only the larger size machines make any provisions for operation at reduced capacity. In some systems, integral cylinder unloading, the installation of a gas engine drive with variable speed control, or even multiple smaller systems, provide a logical solution.

The Series 9000 high-pressure manual pinch valve is designed with ANSI Class 300 flange drilling. The heavy-duty elastomer sleeves are reinforced with high strength nylon, polyester fabrics, or Kevlar® material. Several heavy-duty sleeve designs are available. The elastomer sleeve will close even on solids, and the flexing action of the sleeve eliminates the possibility of scaling. Two heavy-duty pinch bars close the sleeve. All valve working parts are isolated from the process by the sleeve. Combining these features with a sealed body design and no packing to maintain, results in a simple, rugged, no-hang-up, maintenance-free valve.
