CONTROL VLVES KOSO HMMEL DHL B U L L E T I N V 5 0 / 5 0 - FETURES Globe bodies for in-line service; angle bodies for difficult service. Each body style accepts all standard trim sets. Balanced plugs for use with smaller more economical actuators. plugs for simplicity of design, fewer parts, and ease of maintenance. Standard linear or equal percentage characterized ported cages; optional linear or equal percentage cages for difficult applications. Series V50/V50 Globe nd ngle Valves /"- 8" (DN5-00) NSI 900- The V50 (NSI 900 and 500) and V50 (NSI ) Series control valves are heavy cage guided type globe and angle valves with quick change trim. Designed for high temperature and high pressure applications, these valves feature a close tolerance integral cage and seat ring for accurate, vibration free service. The pressure drop in this design occurs across the cage openings (ports) rather than the seating surface, thus minimizing seat wear and seat leakage. pplications include throttling and on/off control of non-gritty liquids, gases, and steam at moderate to high temperature and pressures. Maximum parts interchangeability and simplicity of design result in minimum parts inventories and lower maintenance costs. Specifications ll cages for a given valve size have constant bore diameters, therefore all plugs are interchangeable regardless of design, requiring fewer part replacements. ( /" - 8" sizes) Cv reductions are achieved by reducing the area of the cage openings, not by changing its diameter or valve travel, thus eliminating the need for changing actuators. Body Style: Cage guided globe or angle Body Size: /" through 8" (5-00 mm) Body Rating: NSI 900, 500 (/" through 8"); NSI (" through ") Body Materials: Carbon steel, stainless steel, chrome-moly steel, other castable alloys End Connections: Socket weld, butt weld, raised face flange, ring type joint and others on application Bonnets: Plain or extension Trim Style: Balanced or unbalanced plug, standard ported or cage with integral seat ring.

Trim Designs The V50 Series and the V50 Series are two separate product lines each designed to be a fully integrated, interchangeable system of parts. While all parts are common within each series, parts cannot be interchanged between series. Standard trim sets for the /" - " NSI 900 and 500 and " NSI valve bodies include a seat ring, a cage that acts as the seat ring retainer and the guide for a contoured plug (Fig. ). Trim sets for all other valve bodies are cages with integral seats and piston style plugs (Figures,, 4, 5, 6). 4 V 5 0 / 5 0 - Figure 4. Balanced Plug The standard balanced plug is piston style, which has a primary metal seat and secondary bidirectional piston rings set in ring grooves. The pressure above the plug is equalized with the pressure below the seat ring by large vent holes which pass completely through the plug. In the closed position, the plug rests on the seating surface machined in the cage and the piston rings seal the anulus between the upper plug and cage. Figure. Seated Cage The standard cage construction is a cast cage with integral seat ring. The cage serves as a massive plug guide and the close tolerance fit eliminates plug vibrations at high differential pressures. The four cage openings are contoured to establish the flow characteristic. The cage shown has openings which will provide equal percentage characteristic. linear characteristic is also available. Figure 5. Optional Balanced Plug This unique design includes a special unidirectional, spring-loaded, pressure-energized TFE cup seal. Upstream pressure enters the seal cavity compressing the seal outward, sealing the annulus between the plug and cage walls. 5 Figure. Flash-Flo This unique cage has a series of diametrically opposed drilled holes that break the flow stream into many smaller streams. For liquid applications, the trim is used as flow into the cage. Thus the high velocity streams impinge upon each other which dissipates the energy and keeps the cavitating liquid away from metal valve parts. For gas/steam applications, the trim is used as flow out of the cage. 6 Figure 6. Plug The unbalanced plug (no vent holes) is used in only flow from under the plug applications. The plug is grooved along its sides to equalize pressure in the valve body above the seat with the pressure above the plug. Thus the high velocity streams radiate out of the cage causing a redistribution of the acoustical energy with resultant noise attenuation. The cage has an integral seat ring. The V50 Series and the V50 Series together fulfill the design concept of a streamline product offering which provides maximum versatility and flexibility, yet requires a minimum of inventory and maintenance time.

NSI IV V IV II III IV V The unbalanced plug used in conjunction with any metal seat ring will provide IV shutoff or may be lapped to provide V shutoff. The standard plug seal for temperatures below 400 F (04 C) is a PTFE piston seal energized by a Viton O ring (refer to Figure 0 for pressure and temperature limitations). Supplied with any metal seated cage, this seal will provide IV shutoff. plug seal for temperatures and pressures beyond the capability of the PTFE piston ring is carbon graphite. This seal supplied with any metal seated cage will provide II shutoff. The standard plug seal for temperatures and pressures beyond the capability of the standard PTFE piston ring is a metal piston ring, which provides III shutoff. For those applications where V shutoff is required in a balanced valve, a special spring-loaded pressureenergized PTFE cup seal is available to be used in conjunction with a lapped seating surface.
