CONTROL VALVES - Series E Globe Valves

Available sizes in the Series ED & ET Globe Valves: 1, 1½, 2, 2½, 3, 4, 6 and 8 inch

Available sizes in the Series EZ Globe Valve: 1, 1-1/2, and 2 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 three 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.

     
  • Design "CVS EZ" valves are globe-style with integral end connections, post guiding, and quick-change trim. These valves are used in chemical or hydrocarbon processing applications or in applications that require control of non-lubricating, viscous, or other hard-to-handle fluids.

*Flow Characteristics are Equal percentage, quick opening,

The flow direction for standard cages ("CVS ED & CVS ET") is flow down, and the flow direction for the CVS EZ is up through the seat ring 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.

CONTROL VALVES - Series V100 Ball Valve

Available in 2 thru 12 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.

ACTUATORS - CVS 657, 667, 1051, 1061

The CVS 657, CVS 667 sizes 30-80, and the CVS 1051 and 1061.

The series CVS 657 is a direct acting, spring opposed diaphragm actuator with a 4-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” for “push-down to open” valves.

The series CVS 667 is a reverse acting, spring opposed, diaphragm actuator with a 4-inch maximum travel. When the signal pressure increases 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 direction. If the signal pressure should fail, the spring will force the stem in the downward position providing “fail-closed action” for “push down to close” valves.

Both the Series 657 and Series 667 actuators are used for automatic operation of control valves used in applications where throttling or on/off service is required.

The series CVS 1051 and 1061 is used for on-off service without a positioner or for throttling service with a positioner. The stroking time is dependent on the actuator size, rotation, spring rate/compression, supply pressure, and size of supply line.

CVS Controls manufactures Control Valves and associated instrumentation products to specification that facilitate the direct replacement with FISHER* process control equipment.

POSITIONERS - CVS-1000R

The CVS Electro-Pneumatic Positioner CVS1000R is used for operations of pneumatic rotary valve actuators by means of electric control for a systems pneumatic output signals of 3-15 psi, or 6-30 psi.

Input signal is DC 4-20mA

The positioner is CSA approved and rated EXdmIIBT5 explosion proof, zone1, class 1, division 1.

Can be reverse acting or direct acting, and is suited for single or double acting actuators.

It is possible to prevent hunting with the correct orifice size for smaller actuators.

The CVS 1000 has a very low air consumption.

Easy to read indicator allows for positioner monitoring from a distance.

It is possible to control the 1/2 split ranges with simple field adjustments without the need to replace parts.
