Class for use in all applications

requiring 800 Limited Class ratings

or below.

Available in 1" nominal pipe size with1/8", 3/16", 1/4" or 5/16" orifice,

depending on desired flow capacities.

A micrometer dial position indicator

allows fast, precise and repeatable

settings.

(ASME SA 105) body with 13%chrome stainless steel trim.

One-piece drop forged body

Graphite packing, complete with

braided graphite filament yarn

anti-extrusion rings, is standard.

All Hancock 5505 series valves

comply with ASME/ANSI B 16.34 and

the ASME Boiler and Pressure Vessel

Code, Section 1.

Applications

In addition to continuous blowdown

service, the Hancock High Pressure

Drop valve is also used on feedwater

bypass relief, sampling systems, drains

and other services where erosion isextremely severe.

Specifically designed to withstand the deleterious effects of continuous blowdown

service so damaging to conventional valves.The high velocity stream of boiler water,

flashing into steam, is forced to expend its kinetic energy within the confines of the

diverging hardened stainless steel delivery tube, thus eliminating damage to the valve

body wall and downstream piping.

Example 1: To determine the correct sizeorifice for an 800 Class Continuous BlowdownValve which will flow 3500 lbs/hr at 800 psiginlet pressure.

A. On the Continuous Blowdown-Wide Open

chart to the right, locate 3,500 on theBlowdown Capacity scale and draw ahorizontal line (a) across the chart fromthat point (see example below).

B. Draw a vertical line (b) from 800 on theBoiler Pressure scale to intersect withthe horizontal line (a).

C. Continue the vertical line (c) until itintersects with the next higher orifice curve(in this case, 3/16").

D. Draw a horizontal line (d) from theintersection of the 3/16" orifice curve tothe Blowdown Capacity line and readthe maximum capacity of the 3/16" orificevalve (3800 lbs/hr).

E. Check to ensure that the selected orifice

will result in the correct valve position toallow for proper control without throttlingtoo close to the seat (see steps F- H).

F. On the Handwheel Turns vs Percent ofWide Open Capacities chart (see page 5),locate the 3/16" orifice curve and draw avertical line (e) from where it intersectswith the 100% open line down to theHandwheel Turns scale. Read the numberof turns to reach maximum capacity of thevalve (2 turns).

G. Determine what percent of the full opencapacity is required to attain the Normalrequired flow rate (Divide the NormalRequired Flow Rate by the Maximum FlowRate and multiply by 100 to obtain thecorrect percentage.) 3500/3800 x 100 = 92%.

H. Verify that the required flow rate will beobtained when the valve is between 1/3 and2/3 open (in this case, between 0.66 and1.33 full turns) by drawing a horizontal line(g) from the 92% point on the capacityscale to intersect with the 3/16" orificecurve.Then draw a vertical line (f) from thatintersection to the Handwheel Turns scaleand read the number of turns open (1.7)required to attain the specified flow (3500lbs/hr).

Since 1.7 turns is much greater than thedesired 1.33 and will result in little or nocontrollability, the next larger size orifice (1/4")should be utilized and the flow rate versusvalve disc position reverified by repeating

steps A through H.

Water Flow Chart

Example 1: To determine the correct sizeorifice for an 800 Class Continuous BlowdownValve which will flow 6000 lbs/hr of water at800 psig inlet pressure with a pressure dropof 400 psi:

A. On the Water Flow chart to the right, locate6000 on the Capacity scale and draw ahorizontal line (a) across the chart fromthat point (see sample chart below).

B. Draw a vertical line (b) from 400 on thePressure Drop scale to intersect with thehorizontal line (a).

C. Continue the vertical line (c) until itintersects with the next higher orificecurve (in this case, 3/16").

D. Draw a horizontal line (d) from theintersection of the 3/16" orifice curve tothe Capacity scale and read the maximumcapacity of the 3/16" orifice valve (8800lbs/hr).


will result in the correct valve position toallow for proper control without throttlingtoo close to the seat (see steps F-H).

F. On the Handwheel Turns vs Percent ofWide Open Capacities chart (see page 5),locate the 3/16" orifice curve and draw avertical line (e) from where it intersects withthe 100% open line down to the HandwheelTurns scale. Read the number of turns toreach maximum capacity of the valve (inthis case, 2 turns).

G. Determine what percent of the wide opencapacity is required to attain the requiredflow rate. (Divide the required flow rate bythe maximum flow rate and multiply by 100to obtain the correct percentage.)

6000/8800 lbs/hr x 100 = 68%H. Verify that the required flow rate will be

obtained when the valve is between 1/3 and2/3 open (in this case, between 0.66 and1.33 full turns) by drawing a horizontal line(g) from the 68% point on the capacityscale to intersect with the 3/16" orificecurve.Then draw a vertical line (f) from thatintersection down to the Handwheel Turnsscale and read the number of turns open(1.2) required to attain the specified flow(6000 lbs/hr).

Since 1.2 turns falls between the optimumrange of 0.66 and 1.33 turns, the 3/16" orificeis satisfactory for the application.

Steam Flow Chart

1" Figure Numbers 5505W (Reference #MM342)

Example 1: To determine the correct sizeorifice for an 800 Class Continuous BlowdownValve which will flow 500 lbs/hr of steam at600 psig inlet pressure with a pressure drop of400 psi:

A. On the Steam Flow chart to the right,locate 500 (0.5) on the Capacity scale anddraw a horizontal line (a) across the chartfrom that point (see sample char t below).

B. Draw a vertical line (b) from 600 on theInlet Pressure scale to intersect with thehorizontal line (a).

C. Continue the vertical line (c) until itintersects with the next higher orifice curve(in this case, 3/16").

D. Draw a horizontal line (d) from theintersection of the 3/16" orifice curve to theCapacity scale and read the maximumcapacity of the 3/16" orifice valve (780lbs/hr).


will result in the correct valve position toallow for proper control without throttlingtoo close to the seat (see steps F-I).

F. On the Handwheel Turns vs Percent ofWide Open Capacities chart (see page 5),locate the 3/16" orifice curve and draw avertical line (e) from where it intersectswith the 100% open line, down to theHandwheel Turns scale (see sample chartbelow, right). Read the number of turns toreach maximum capacity of the valve (inthis case, 2 turns).

G. Calculate the percent of Wide OpenCapacity necessary to attain the desiredflow rate (divide the required capacity bythe maximum capacity):

500/780 x 100 = 64%H. Determine the number of turns open

required to attain the required flow rateby drawing a horizontal line (f) fromthe 64% point on the Percent of WideOpen Capacities scale to intersect withthe 3/16" orifice curve. Then draw avertical line (g) from that intersectiondown to the Handwheel Turns scale.Read the number of handwheel turnsneeded to attain the desired flow (inthis case,1.20).

I. Verify that the disc will be positionedwithin the proper range (between 1/3and 2/3 open, which in this case isbetween 0.66 and 1.33 full turns)

Since 1.2 turns is well within the properrange of 2/3 to 11/3 turns, the 1 inch valvewith a 3/16" diameter orifice is satisfactoryfor the application and will allow for goodcontrol, both above and below the specifiedflow rate, without getting thedisc too close to the seat.

The required valve size, flow rate ordifferential pressure can be determined fromthe nomographs on pages 4 through 7, orthrough the use of the formulas below. FlowCoefficients (Cv) can be found on page 3.

When determining the required valve sizeeither through the use of flow coefficients (Cv)

or the graphic method, it should be noted thatthe resultant valve size is the size that will givethe required flow (or Cv) in the full openposition. For optimum controllability, a controlvalve should be sized using a 25% greaterflow capacity than the maximum required forthe desired operating conditions.Selection ofa valve on this basis allows for controlvariations above and below the calculated flowrate.

NOTE: For gas or steam, the maximumdifferential pressure (P) cannot exceed1/2 P1 - (Minimum P2 =

1/2 P1)

The formulas shown may be used to calculatevalve capacities or required flow coefficients.

P1 = Inlet Pressure (psia)

P2 = Outlet Pressure (psia)

P = Pressure Drop (psi)

G = Specific Gravity of Liquid (water = 1.0)
