SERIES ED AND ET CONTROL VALVES
	1-16 Inch The CVS Series E is a single port, globe style body with composition or metal seats, and a balanced valve plug. Design ED: Intended for general control application over a wide variety of temperature and pressure drops. The ED has an upper piston ring seal and metal to metal seating. Design ET: Used in application requiring low leakage rates. The flow direction for standard cages is flow down, with the following characteristics available: linear, whisper, quick opening and equal percent. The end connections are ASME Class 150, 300 and 600 raised face or ring type joint flanges as per ASME b16.34-latest edition, and butt weld, threaded on the 1" &2" only.
SERIES EWD, EWS AND EWT CONTROL VALVES
	The CVS series EWD valve bodies are single port, globe style bodies with cage guiding, clamped seat rings and push down to close valve plug action. The series features large end connections and expanded internal flow cavities. The series is available 8X6, 10X8,12x^ and 12X8 inch sizes. The first number refers to the line size and the other refers to the trim and bonnet size. Design EWD: Intended for general control applications over a wide variety of temperatures and pressure drops. This design has a a balanced valve plug with metal-to-metal seating. Design EWS: Intended for applications requiring better shut-off capabilities than the EWD. This valve uses an unbalanced valve plug with metal-to-metal seating, or optional metal-to TFE seating. Design EWT: Suitable for applications with stringent shut-off requirements. Uses a balanced valve plug with metal-to-TFE seating or metal-to-metal seating for use in higher temperatures.
SERIES D GLOBE VALVE AND DA ANGLE VALVES
	1 &2 Inch 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 & gas production, distribution systems and power plants. These valves are especially useful for throttling or on/off control of liquids or gases. 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 with tungsten carbide inserts or stellite overlay.
SERIES H900/H1500/H2500 CONTROL VALVES
	The HD2 Design is a single port, globe style body with cage guiding and balanced valve plug. Metal seat, piston rings are used to provide the seal between the valve plug and cage. This configuration is used for general applications where tight shut-off is not required. The H5T design is a single port, globe style body with cage guiding, balanced valve plug, metal seat, and pressure assisted spring seal to provide the seal between the valve plug and cage. It is designed for the applications that require low leakage rates.
SERIES HPS/HPAX
	2 TO 6 Inch, 2 Inch Angle Valves CVS HPX Control Valves are designed for high pressure applications in the process industry. Valves are cage guided with metal seats and quick change trim. Balanced plugs are push down to close. The HPX is a straight globe valve while the HPAX is an angled valve. Series HPX2D & HPAX2: A piston ring provides the seal between the cage and the balanced valve plug. Series HPX5D and HPAX5: Sealing is provided by pressure assisted seal ring.
SERIES 128 PAQ
	The CVS Series 128-PQC Control Valves are suitable for on/off dump valve service in oil & gas production applications, in either sweet or sour gas conditions. These valves are also useful for on/off high pressure control of numerours gases and liquids and can be used with materials that are viscous or erosive. This is a single port valve with unbalanced stem-guided valve plug and push to close valve action. Operated by a type 128 spring and diaphragm actuator, the assembly can be operated in normally open or normally closed applications. This setting can be reversed in the field with minimal disruption and no additional parts.
V100 BALL VALVE
	2-8 INCHES SIZES The CVS V100 Ball Valve design utilized 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. These can be mounted horizontally or vertically on the right or left-hand side viewed from forward flow inlet.
PNEUMATIC ACTUATORS
657 bulletin 667 bulletin	The VCS Series 657 is a direct acting, spring opposed diaphragm actuator wit ha 3 inch maximum travel. Signal pressure supplied to the upper housing chamber forces the stem downward. When the signal pressure is reduced, the compressive force on the spring moves the stem upward. If the signal pressure should fail, the spring will force the stem in the upward direction providing "fail-open action?" The CVS Series 667 is a reverse acting, spring opposed, diaphragm actuator with a 3 inch maximum travel. When the signal pressure increased to the lower diaphragm casing, the actuator stem is forced upward compressing the spring. When the signal pressure is reduced, the spring moves the actuator stem in the downward position. If the signal pressure should fail, the spring will force the stem in the downward position providing a "fail Closed" action.
MISCELLANEOUS
	The Oil Thief is a simple, one spring device for taking accurate samples of the tank bottom. Features include one-line, adjustable controls, adjustable hanger, and replacement valve seat. Choice of bronze or aluminum body.
