SINGLE SEATED BALANCED PLUG CAGE GUIDED GLOBE VALVE
97/98-41000 Series Pneumatic Cage Guided Control Valve
41000 Series cage guided valve produced with masoneilan technique are designed for applications involving Pressure drops and temperatures beyond those for which the 21000 series are suitable. 41000 series valves are Equally suited for gas and liquid applications: Both low noise and anti-cavitation trim are available. The type of 97/98-41000 pneumatic control valve is composed of 41000 cage guided valve and pneumatic diaphragm Multi-spring actuator which is self-developed and meets the standards of IEC. It not only has the small volume And light weight actuator, but also has the advantages of 41000 series cage guided valve, such as large capacity, and Higher allowable pressure drop. It is a kind of ideal actuator. Receiving control signal from control instrument, automatically Controlling the opening of valve to attain the constant control of the technological parameters, such as pressure, Temperature, flow, level. Automatic control in producing process can be achieved. Therefore it is widely applied Into auto control system of power, petroleum, metallurgy, chemical industry, textile and other industrial departments.
Features:
High Capacity with Low Recovery
Capacity for the 41000 series valve exceeds the levels established for contemporary cage Type globe valves. These capacities are attained with low pressure recovery, as indicated By high critical flow factors of 0.90 to 0.94. Thus the possibility of cavitation on liquid service Is minimized.
High Allowable Pressure Drops
The 41000 series will handle a wide range of pressure drops encountered in severe service.
Tight Shutoff
Single seated leak tightness in accord with ANSI B16.104 Class IV or Class V, can be Provided.
Wide Temperature Range
The 41000 series handles temperature from -195 ~566 degrees. An extension bonnet is Available for temperature above 201 degrees and below -18 degrees.
Simple, High Performance Trim Packages
Virtually every valve is available with standard and reduced Cv's.
High Performance Material are standard
Without exception, 41000 series materials have been selected to handle the maximum Inlet pressure and maximum pressure drop in their temperature range. So, specification is Simplified and longevity on any application is assured.
V-FLO Group of Companies, originally known as V-FLO Pumps & Systems, was established in 2001 in the form of corporation with 14 strongest and carefully qualified pump manufacturers in China. All these 14 manufacturers are ISO certificated companies and some of them were founded as early as in 1949. V-FLO, on top of these companies and based on their cooperation with world leaders of the field including Ebara, Nash Elm, Allweiller, Boremman, Dresser, KSB, Sulzer and Byron Jackson, has grown to be the strongest pump developer, pump station solution provider and equipment supplier in China.
V-FLO started from pumps but now we are much more than the pumps. In addition to the pump manufacturing section, we have developed to cover a system engineering for EPC projects as well as general trading business, especially focusing on the design, manufacturing and OEM packaging of all types of special industrial process and production lines with supports and partnerships from all the senior R&D organizations and experienced manufacturers all over China for different industries.
V-FLO has started a new journey to serve our customers in diversified industries for power, oil & gas, chemical and other industries. This can be translated into a wide scope of services. V-FLO offers from private basement to municipal sewage treatment, from the boiler room in a high rise building to a marine pier, in processing plants, power generating stations, paper mills, construction sites, utility maintenance fleets and in farm fields as well.
V-FLO Group, with two factorices we are cooperating, has more than 2500 employees working at positions of manufacturing, R&D, sales and management. We are dedicated to strive for a higher standard of service not only in providing pumps, motors, expansion tanks, valves, specialized equipments and so on, but also in EPC, engineering design and project planning and even a lot more. Our investment in technology and research is second only to the support we give to our customers and employees. We approach the 21st century reaffirming our dedication to our customers, employees and vendors.
