DESCRIPTION

The Bell & Gossett Model MV is a combination calibrated bal-

ance, commissioning and positive shutoff valve for use in

HVAC systems. An efficient brass venturi design provides

accurate flow balancing with minimal system pressure loss.

Valves are furnished with two readout valves (pressure and

temperature p

orts), standard port ball valve with memory

stop, and a hanging ID tag for commissioning. A variety of

end connections are available on both the fixed and union

ends.

Venturi/Ball valve provides highly accurate flow measurement

capabilities.

INSTALLATION INSTRUCTIONS

1. For installing Sweat Connections:

a) Clean tube ends and valve connections thoroughly per

good piping practices with a fine grade emery clot

h or

fine grit sandpaper.

b) For soldering, use 95-5 (Tin-Antimony) solder and a

good grade of flux.

c) Use a torch with a sharp pointed flame.

d) When sweating the joints, first adjusting the valve in the

full open position, then wrap the valve with a cool wet

rag and then direct the flame with care to avoid subject-
