ntroduction

These pressure actuated modulating valves

control the quantity of water to a condenser by

directly sensing pressure changes in a

refrigerant circuit. The valves can be used in

non-corrosive refrigerant systems. Ammonia

power elements and valves designed for salt-

water applications are available. The valves

have a quick opening characteristic and open

on pressure increase (direct acting). Reverse

acting (close on pressure increase) is possible.

Series V46

Pressure Actuated Water Regulating Valve

Feature and Benefits

! Pressure balanced valve design Setpoint is independent from water inlet pressure

! High refrigerant pressure resistant

bellows

Refrigeration pressure may increase up to 28 bar

without bellow damage

! Pressure actuated Direct and fast response to pressure variations

! 3/8, 1/2, 3/4" are angled body type

valves with high Kv value

Small dimensions with high flow capacity

! 3/8" up to 2" pressure valves "all

range" types

Reduces stock. One valve for all non-corrosive

refrigerants

! Quick opening valve characteristics Fast response to pressure increase

! No close fitting or sliding parts in

water passages

No hysteresis increase or stuck valve caused by

contamination

! Easy to disassemble. All parts can

be replaced

Valve can easily be repaired "in line". Valve piece

parts are available "world-wide"

! Special bronze bodies and monel

parts

Used for sea water applications

! Power elements with stainless steel

bellows available

For use on ammonia filled equipment

! Wide range of pressure connection

styles

Possibility to meet the legislation in your country

! Nickel plated seats available for 3/8,

1/2, and 3/4" valves

High resistant against erosion/ corrosion and

cavitation

! Direct/reverse action Control action can be (factory) changed

V46 Issue 9911 2 Note All series V46 water regulating valves are designed for use only as operating devices. Where system closure, improper flow or loss of pressure due to valve failure can result in personal injury and/or loss of property, a separate pressure relief or safety shut off valve, as applicable, must be added by the user.

V46 Issue 9911 3 Valve size selection by the use of the diagram page 4 3 Q: The quantity of water (m /h) is indicated on the left side of the upper diagram (= scale A). ∆ P: The curves for the pressure drop across the valve are indicated in the lower diagram (0,1 up to 4 bar, see scale C). Solution: 3 a. Draw a horizontal line through 6 m /h (scale A) and determine the intersection of this line 3 with the /4" valve curve. b. Draw a vertical line from this intersection point to the 2,5 bar HPR line. c.

V46 Issue 9911 5 Ammonia (NH3)applications Repair and replacement For all larger valve types an ammonia element is available. These elements have style 15 pressure connection and consist of a stainless steel bellow in a steel cup (coated). The existing element can be replaced by this ammonia element. The pressure range does not change. For the high range valves (V46AS/AT/BS/BT) the spring inside the power element has to be placed in the ammonia element.
