Fisherr 655 and 655R Actuators for Self-Operated Control

Fisher 655 and 655R diaphragm actuators, in combination with Fisher valves, provide control for a wide variety of pressure regulation applications. The 655 is used for pressure reduction service on push-down-to-close valves, and the 655R is primarily for pressure relief use on push-down-to-open valves. These actuators may be either self-operated or remote-loaded.

Features

Versatility–Typical industrial service includes pressure control of water, steam, oil, gas, and other fluids. Actuators can be operated by pneumatic switches, solenoid valves, pilot valves, or remote panel loaders for shutoff service.

Large Valve Body Selection–easy-e valves up through the NPS 4 (NPS 6 for Fisher EA angle valves) with wide choice of end connections, flow directions, flow characteristics, valve plug designs, and seating constructions can be specified.

Broad Actuator Spring Selection–Spring of the proper rate is available for nearly any control valve application. Spring selection procedure is quick and accurate.

Severe Service Capability–Rugged yoke and casings help provide stability and corrosion protection.

Fast Acting– Direct-operated configuration provides faster speed of response.

6.Average for minimum and maximum pressures at zero and 0.25 inch travels.

Installation

These regulators may be installed in any position, as orientation is not a problem. But for steam service, the control line should be installed so that condensate drains back into the diaphragm casing, thus maintaining a water seal on the diaphragm. A strainer (such as the Fisher 262K) is always recommended ahead of the valve body to protect body and trim from damaging particles.

Dimensions are given in figure 1. Refer to the appropriate instructions before installing the regulator.

Ordering Information

When ordering, specify:

1.All information requested in the Ordering Information section of the valve body bulletin.

2.Actuator type number and size

3.Actuator travel

4.Valve plug stem diameter and connection size

5.Desired regulator orientation in pipeline

6.Magnitude and type of remote loading pressure, if applicable (for instance, 3-15 psig controller output signal)

7.Desired actuator options

Total Capability of Fisher 655-ED

The following charts (figures 2 through 11) show the complete capability of the 655-ED, including travels greater than 0.25 inch. Included are charts for Cv, Cg, and Cs for the ED valves of various sizes and charts for various casing sizes for the 655 actuator.

An example on the use of the charts follows:

1.Refer to the chart showing the Cv for the ED design. Assume your customer says his normal Cv is 37, but can vary from 30 to 44 and the customer wants to control at 110 psi. The NPS 2 will fit this quite well and at the top of the chart you will notice that this requires a travel from 0.25 inch to 0.375 inch with the normal travel at 0.3125 inch.

2.Next, refer to the curve on the 655-ED, A-CASING chart of diaphragm pressure versus valve travel. Enter

the chart at 0.3125 inch valve travel and proceed up until you intersect the 110 psi pressure. You will note that spring drawing 1F7143 is at this intersection. You can then readily see that when the flows vary, the pressure will vary from approximately 118 psi to 105 psi as the valve travels from 0.25 inch to 0.375 inch.
