The direct-acting V46 pressure-actuated modulating valves typically regulate refrigerant head pressure in water-cooled condensers.
You can use commercial V46 valves with standard noncorrosive refrigerants. For applications where the coolant may be corrosive to the valve trim, maritime models are available, which have nickel copper MONELĀ® valve trim.
