With its Copes-Vulcan brand, SPX FLOW has
been providing control valves and desuperhe-
aters for the power, process and nuclear
industries since 1903. SPX FLOW provides a
wide range of valves for control of pressure,
temperature and flow-induced noise in all types
of power plants. Products include severe service
and general service control valves, variable orifice
desuperheaters, RavenTM, trim and steam-con-
ditioning valves and nuclear control valves, as well
as custom designed specially valves. The Copes-
Vulcan brand is recognized worldwide as a leader
in valve for severe and critical service applications.
Our Strength lies in our ability to provide innovative
valve solutions for our customers’ application needs.
Finding innovative ways to help the world meet
its ever growing demand for power is a key
focus for SPX FLOW so we can provide creative
solutions that serve global energy markets in a
myriad of ways. Our ideas are helping build more
efficient power plants and renovate older existing
facilities. SPX FLOW supplies a wide range of co-
mponents – from air preheaters to filter systems
for nuclear, coal-fired, combined cycle, solar,
thermal and geothermal power plants. With ope-
rations in over 35 countries, SPX FLOW has the
global experience and regional presence, products
and powerful ideas it takes to help our customers

GV-200 Series cage control valve is a kind of high performance pressure balancing control valve produced by our company through introducing advanced technology from abroad. In this series valve, the structure of body is compact, the plug can realize complete guiding through cage with good anti-vibration performance and the high performance seal ring are adopted for sealing so as to enhance the leakage level. It has such features as small volume, light weight, small pressure drop loss, large flow, wide rangeability, highly precise flow characteristic curve, good dynamic stability, low noise, small cavitation corrosion and small leakage. The series products can be widely used in the occasions where the allowable pressure drops is relatively higher.
The structure of large stroke and complete guiding enhances the stability of plug under large pressure, reduces side load and plug vibration, and prolongs the service life of valve.
The standardized and modularized design makes the performance more reliable.
The piston ring and high performance seal ring are adopted for sealing so as to enhance the leakage level.
The packing box adopts maintenance-free self-tightening sealing design, which is more safe and more reliable.
The packing box system is additionally provided with dust cover to effectively prevent dust and sundries from entering into the packing box.
The body is completely interchangeable with that of single seat valve, and the online replacement of valve trims can be realized.
The pressure containing parts are designed in accordance with ASME nuclear power level standard, with more safe use and being more applicable to severe working conditions.
The control valve is allocated with new generation high performance actuator as a standard. With compact structure and large output force, it is suitable for controlling various media of different pressure and temperature.

globe style bodies feature smooth, streamlined, constant -area internal passages with no pockets, permitting high capacity with minimum turbulence. They are designed with nearly constant wall thickness, providing lower weight and cost when manufactured in expensive stainless or alloy steels.

The standard bonnet enable the forming of a Deep packing box together with a long guide Housing there by providing a robust and vibration resistant assembly. Teflon rings are the standard packing up to 250 ℃.Protects the packing from excessive heat or cold, which may adversely affect valve or packing performance. Application temperature range depends upon valve and bonnet construction materials.
Provides for a positive metalic gland seal within the rate pressure and temperature of the bellows metarial selected. Use on hazardous, lethal service an auxiliary packing box in the upper bonnet serves as a back up seal in the unlikely event of a bellows failure.Permits stagnated moderate temperature gas to from within the bonnet which protects the packing from the extremes of temperature produced by the line fluid. Normally constructed in stainless steel it operated to – 196℃

Equal Percent
The flow characteristic describes the relationship between the flow coefficient and the valve stroke. It is inherent to the design of the selected valve. For example, as the valve is opened, the flow characteristic allows a certain amount of flow through the valve at a particlar percentage of the stroke. This is especially important for throttle control because it controls the flow in a predictable manner. The flow rate is affected by the flow characteristic as well as the pressure drop. Inherent flow characteristic is when the valve is operating with a constant pressure drop without taking into account the effects of piping. Installed flow characteristics consider both the valve and piping effects. This is also considered an ideal curve and takes the entire system into account.
Equal percentage is the characteristic most commonly used in process control. The change in flow per unit of valve stroke is directly proportional to the flow occurring just before the changeis made. While the flow characteristic of the valve itself may beequal percentage, most control loops will produce an installed characteristic approaching linear when the overall system pressure drop is large relative to that across the valve.
An inherently linear characteristic produces equal changes in flow per unit of valve stroke regardless of plug position. Linear plugs are used on those systems where the valve pressure drop is a major portion of the total system pressure drop.
Quick opening flow is characterized by the maximum flow produced immediately as the valve begins to open. It is only used for on-off applications and due to the extreme nature of the flow, the inherent and installed characteristics are similar.
