1 Pressure ctuated Water Valves V46 2-way Pressure ctuated Water Valves - ommercial pplications 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. mmonia power elements and valves designed for salt-water applications are available.

7 Pressure ctuated Water Valves V46S Pressure ctuated Water Valves, Low low refrigeration components The V46S is a direct acting, all range, pressure actuated modulating valve, used to control the waterflow to a condenser by directly sensing pressure changes in a non-corrosive refrigerant circuit. The V46S is specially designed for use on equipment requiring a low condenser waterflow such as icemakers, small heatpumps and watercoolers. The springhousing and power element are rolled to the valve body. Rubber diaphragms seal the water away from the range spring and bellows part so these are not submerged in water where they would be subject to sedimentation and corrosion. The valve can be ordered style 5 (without capillary), style 13, style 34 and style (incl. cm capillary). The capillary part will be delivered separated from the valve. eatures zvalve designed for low flow z ll range power element and spring housing zsmall dimensions zpressure actuated zvarious pressure connection style zhigh refrigerant pressure resistant bellows imensions in mm (bar) ody SizeThread according to ISO 228 apillary Length Ordering odes V46S V46S-9110 apillary separate V46S Straight 3/8 V46S apillary separate V46S-99 V46S dditional eatures It is possible to change 13 into 45 by ordering KIT031N600 apillary soldered to power element apillary soldered to power element 213

8 Pressure ctuated Water Valves V48 3-way Pressure ctuated Water Valves refrigeration components These watervalves are especially designed for condensing units cooled either by atmospheric or forced draft cooling towers. They may be used on single, or multiple condenser hook-ups to the tower. The type V48 valve senses the compressor head pressure and allows cooling water to flow to the condenser, to by-pass the condenser, or to allow waterflow to both condenser and by-pass line in order to maintain correct refrigerant head pressure. further advantage of this system is that the 3-way valve permits a continuous water flow to the tower so the tower can operate efficiently with a minimum of maintenance on nozzles and wetting surfaces. The valves can be used in non-corrosive refrigerant systems. mmonia power elements and valves designed for salt-water applications are available.

10 Pressure ctuated Water Valves V246 and V248 Water Regulating Valves for High Pressure Refrigerants refrigeration components The V246 & V248 Series 2-way and 3-Way Pressure-ctuated Water-Regulating Valves for High-Pressure Refrigerants regulate water flow and control refrigerant head pressure in systems with single or multiple watercooled condensers. These valves have an adjustable opening point in a refrigerant pressure range of 200 to 400 psig (13.8 to 27.6 bar). These Series valves are designed specifically for condensing units cooled either by atmospheric or forced draft cooling towers. They are used on single or multiple condenser hook-ups to the tower to provide the most economical and efficient use of the tower. V246 & V248 valves may be used with standard non-corrosive or ammonia refrigerants. or applications where the coolant may be corrosive to the internal parts, maritime models are available, which have nickel copper (Monel ) internal parts. eatures zno lose itting or Sliding Parts in Water Passages zccessible Spring ztake-part onstruction zpressure-alanced esign zorrosion-resistant Material for Internal Parts Standard Production Models to 27.6 bar Product odes onstruction Valve Size and onnection lement Shipping Weight (kg) V246G1001 3/8 in.
