　　Series E Globe Valves

　　Available in sizes 1, 1?, 2, 2?, 3, 4, 6 and 8 inch

　　The CVS Series E is a single port globe-style body with composition or metal seats and a balanced “push-down-to-close” valve plug.

　　There are two styles of valves available:

　　Design “CVS ED” is intended for general control application over a wide variety of temperature and pressure drops. Design “CVS ET” is intended for applications requiring low leakage rates with composition seating (TFE) for tight shutoff requirements or metal-to-metal seating for higher temperature capabilities. The valve plug has a two-piece upper seal. The flow direction for standard cages is flow down, with the following flow characteristics available: linear, quick opening, and equal percent. The end connections are ANSI Class 150, 300 and 600 Raised Face or Ring Type joint flanges as per ASME B16.34-1996. Valve bodies are available in LCC, WCB and 316sst material. CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.

　　Series EW Globe Valves

　　Available in sizes 4x2, 8x4, 8x6 and 12x6 inch

　　The CVS Series EWD, EWS and EWT valve bodies are a single port globe-style body with cage guiding, clamped seat rings and “push-down-to-close” plug action.

　　There are three styles of valves available:

　　Design “CVS EWD” is intended for general control application over a wide variety of temperature and pressure drops. This design has a balanced plug with metal-to-metal seating. Design “CVS EWS” is intended for applications requiring better shutoff capabilities than those suitable for the EWD. This valve uses an unbalanced valve plug with metal-to-metal seating or optional metal-to-TFE seating. Design "CVS EWT" is suitable for applications with stringent shutoff requirements. This valve uses a balanced valve plug with metal-to-TFE seating, or metal-to-metal seating for higher temperatures.  The flow direction for EWD and EWT is normally flow down, and the EWS is normally flow up with the following flow characteristics available: linear, quick opening, and equal percent. The end connections are ANSI Class 300, 600, and 900 Raised Face or Ring Type joint flanges. Buttwelded ends are available in Schedule 40 or 80 for class 300 and 600 and schedule 80 or XXS for class 900. Valve bodies are available in LCC, WCB and 316sst material. CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.

　　Series D Globe Valves

　　Available in 1 or 2 inch sizes

　　The CVS Series D is a single port, screwed-in, metal-seated globe style valve with unbalanced post-guided plug and push-down to close plug action used for high-pressure applications. These valves are used in oil and gas production, distribution systems and power plants. These valves are especially useful for throttling or on/off control of liquids or gasses. The flow characteristic is equal percent, and the flow direction is up through the seat ring and past the valve plug. This valve is available with cast integral flanges, welded flanges or screwed connections. The valve plug and seat ring can be fitted tungsten carbide inserts or satellite overlay. Please contact your CVS Controls sales representative for availability and delivery time. Valve bodies are available in LCC, WCB and 316sst material. CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.

　　Series H1500 Lb. Design Bodies

　　Available in 3, 4 and 6 inch sizes

　　Design “H2D” is a single port globe-style body with cage guiding, balanced valve plug and metal seats. This configuration is used for general applications where tight shutoff is not required. Design “H5T” is a single port, globe-style body with cage guiding, balanced valve plug and composition or metal seats. The valve plug has a two-piece upper seal and is designed for applications that require low leakage rates. The flow direction is through the cage openings and out through the seat ring (flow down). Flanged end connections are raised face, and ring-type joint. The three types of flow characteristics available are: quick opening, equal percentage and direction is flow down. Valve bodies are available in LCC, WCB and 316sst material. CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.

　　Series HPX Control Valve

　　Available in 2, 3, 4 and 6 inch sizes

　　The HPX Control Valve is a rugged single port high-pressure globe valve, with metal seats, quick-change trim and push down to close plug action. The HPX2 uses a balanced valve plug, and piston rings are used to provide the seal between the valve plug and cage. The HPX5 uses a balanced valve plug, and a pressure-assisted spring seal to provide the seal between the valve plug and cage. For standard cages, the flow direction is flow down with the following flow characteristics: equal percentage, modified equal percent, and linear. The end connections are Class 900 and 1500 raised face and ring type joint flanges as per ANSI B16.34 196. Valve bodies are available in LCC, WCB and 316sst material. CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.

　　Series V100 Ball Valve

　　Available in 2, 3, 4 and 6 inch sizes

　　The CVS V100 Ball valve design utilizes a standard ball with a triangular shaped wedge formed in it. This design allows for both throttling control and on/off service used in conjunction with a variety of actuators. The CVS V100 valve design closes against one of several available ball seals with a shearing action. The CVS V100 is a flangeless design and allows the valve body to fit between two exiting flanges. The flow characteristic is modified equal percent, with normal (forward) flow into the convex side of the Ball. Bi-directional flow is into either side of the V-Ball. TCM ball seal, metal ball seal and flow-ring construction can be used in Bi-directional flow. Typical actuators used are the pneumatic spring and diaphragm rotary actuator (CVS1051) and the pneumatic piston rotary actuator (CVS1061). Mounting of these actuators can be on the right-hand or left-hand side viewed from the forward flow inlet. Valve bodies are available in LCC, WCB and 316sst material. CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.
