V148 Series Three-Way Pressure-Actuated Water-Regulating Valves
Code No. LIT-1900164
Description
The V148 Series Three-Way
Pressure-Actuated Water-Regulating Valves
regulate water flow to control refrigerant head
pressure in systems with single or multiple
water-cooled condensers. The V148 valves
are designed for applications with system
water pressures of up to 350 psi (24.1 bar),
such as high-rise buildings.
V148EK and V148AL valves have an
adjustable opening point in a refrigerant
pressure range of 145 to 190 psi (10.0 to
13.1 bar). V148EK and V148AL valves are
available in 3/4 in. and 1 in. sizes. Use these
valves with standard, non-corrosive
refrigerants.
V148GK1 and V148GL1 valves have an
adjustable opening point in a refrigerant
pressure range of 200 to 400 psi (13.8 to
27.6 bar). The V148GK1 and V148GL1
Valves are available in 3/4 in. and 1 in. sizes
for use with standard, non-corrosive,
high-pressure refrigerants.
Refer to the V148 Series 3-Way
Pressure-Actuated Water-Regulating Valves
Product Bulletin (LIT-121712) for important
product application information.
Features
no close-fitting or sliding parts in water
passages
high water pressure design
pressure-balanced design
corrosion-resistant material for internal
parts
accessible range spring
take-apart construction
Applications
Each application is unique and requires
specific engineering data to properly size and
design a system to fulfill the appropriate
requirements. Typically, a valve is replaced
with another valve of the same size in a
properly sized and engineered system.
