The V46 pressure-actuated modulating valves come in two types of control action: direct acting or reverse acting. Direct-acting V46 valves are typically used for regulating refrigerant head pressure in water-cooled condensers. Reverse-acting V46N valves are typically used for bypass service on refrigeration systems and heat pump applications.

Commercial V46 valves may be used with standard non-corrosive refrigerants. V46 models are also available for ammonia refrigerant. For applications where the coolant may be corrosive to the valve trim, maritime models are available, which have nickel copper (monel) valve trim.

Benefits

Provides robust control in less than ideal conditions.

Promotes longer valve life.

Allows easy manual flushing, if required.

Allows access to interior of valves without removing the valve from refrigeration system or pumping down.

Maintains consistent setpoint against both gradual and sudden water pressure changes.

V46 Pressure-Actuated Water-Regulating Valve Product Bulletin 1

Application Overview

The V46 direct-acting models open on an increase in pressure. Models A, B, and C are typically used for regulating water-cooled condensers, while the low flow

D model is generally used in ice machines. The reverse-acting V46N valve model closes on an increase in pressure and is typically used for bypass service on refrigeration systems and heat pumps that control water temperature.

Commercial V46 valves are available in 3/8 in. through

2-1/2 in. sizes. Commercial all range models (3/8 through 1-1/2 in.), may be used with standard non-corrosive refrigerants, or ammonia refrigerant applications, depending on the model.

V46 Series valves also come in models designed for

Navy or maritime salt water applications. These valve bodies are constructed of bronze, and any metal parts that come into contact with salt water are constructed of nickel copper (monel), which withstands the corrosive action of salt water.

IMPORTANT: The V46 Pressure-Actuated Water-

Regulating Valve is intended to control water flow under normal operating conditions. Where failure or malfunction of the V46 valve could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system.

Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the V46 valve.

Valve Sizing

Follow Steps 1 through 3, and use the information obtained to locate a point on one of the flowcharts

found under V46 Flowcharts

that satisfies all three steps.

1.

Determine maximum water flow required using tables provided by the manufacturer of the condensing unit, or calculate the flow using the following formula:

Figure 4: Flow Equation

Note: If the outlet water temperature is unknown, assume it to be 10

°F below the condensing temperature.

Example: A 9-ton capacity system has an inlet water temperature of 65

°F and an outlet water temperature of 95

°F. The maximum required water flow is:

Figure 5: Example

2.

Determine refrigerant head pressure rise above the valve opening point.

a.

Valve closing point (to assure closure under all conditions) must be the refrigerant pressure equivalent to the highest ambient air temperature the equipment will be subjected to in the off cycle. Read this in psig from a

Saturated Vapor Table for the refrigerant selected.

b.

To determine the valve opening point, add about 7 psig (48 kPa) to the closing point.

c.

From the same table, read the operating head pressure corresponding to the selected condensing temperature.

d.

Subtract the valve opening point from the operating head pressure. This gives the head pressure rise.

3.

Determine water pressure drop across the valve.

This is the pressure actually available to force water through the valve.

a.

Determine minimum water pressure available from city mains or other sources.

b.

From condensing unit manufacturer’s tables, read the pressure drop through condenser corresponding to the required flow.

c.

To the value found in 3b, add the estimated or calculated drop through installed piping.

d.

Subtract the total condenser, piping, and static head (if applicable) pressure drop from the available water pressure found in 3a. This is the available pressure drop across the valve.

4.

Select the proper valve size from the V46 flowcharts by locating a point on a chart that will satisfy the flow, the head pressure rise above opening point, and the pressure drop across the valve.

Example: The required flow for a low-range system is found to be 27 GPM. Condensing pressure is

125 psig, and the maximum ambient temperature is estimated at 86

°F. City water pressure is 40 psig and the manufacturer’s table gives a pressure drop through the condenser and the accompanying piping and valves at 15 psi. Drop through the installed piping is approximately 4 psi.

Step 1: 27 GPM

Step 2: Closing point is pressure of refrigerant corresponding to 86

°F = 93 psig

Opening point = 93+7 = 100 psig

Operating head pressure = 125 psig

Head pressure rise = 125-100 = 25 psi

Step 3: Minimum pressure = 40 psig

Pressure drop through condenser = 15 psi

Combined pressure drop = 15+4 = 19 psi

Pressure drop across valve = 40-19 = 21 psi

Using a flow of 27 GPM, a head pressure rise of 25 psi, and a pressure drop across the valve of 21 psi, the only valve that satisfies all three criteria is a 1-1/4 in. valve.

See the 1-1/4 in. V46 - All Range chart on the next page.

Flush water lines to clear any foreign matter that may interfere with valve operation. Mount valves vertically on the inlet side of the condenser with spring housing up. If it is necessary to keep the condenser flooded with coolant, the valve can be mounted on the outlet side. When mounting the valve in a position other than vertical, follow the instructions of the equipment in which the valve will be installed. Make refrigerant head pressure connection to bellows. If additional capillary tubing is required, use 1/4 in. O.D. tubing or larger.

!

CAUTION: Risk of Environmental and

Property Damage.

Avoid sharp bends in the capillary tubes.

Sharp bends can weaken or kink capillary tubes, which may result in refrigerant leaks or restrictions of flow.

Adjustment

Valves may be adjusted with standard service valve

wrenches or screwdrivers; see Table 6. All range valve

settings can be changed quickly from low-range refrigerants, such as R134, to high-range refrigerants, such as R22, or from high range refrigerants to lowrange refrigerants. To raise the valve opening point, turn the adjusting screw, located at the top of range

spring housing, counterclockwise. See Table 6

and

Figure 19. Turn the adjusting screw clockwise to lower

the opening point. Exact settings can be made using a pressure gauge in the refrigerant line to determine the throttling point. Put the system under normal operating load and adjust to the desired operating pressure. See

Table 15 for pressure range specifications.

If the compressor operates in high ambient temperatures, head pressures may remain high enough during off cycles to prevent the valve from closing completely. In such instances, the opening point of the valve should be raised just enough to cause the valve to close during compressor standby periods. This will also raise the throttling point.

Manual Flushing

To clear any sediment that might accumulate, valves may be manually flushed. Insert screwdrivers under both sides of the valve spring guide and lift upwards to

flush the valve. See Figure 19. Manual flushing does

not affect valve adjustment.

Figure 19: Manual Flushing
