tion in any position from fully opened to fully closed. Also see Section 3.6 “Torrent SVS
Valves” on page 44.
Each discharge valve may be equipped with a drain. Opening the drain before uncou-
pling the hose relieves the pressure in the line and drains remaining water from the
pump during freezing conditions.
Drain Valves
Various types and styles of manual and automatic drain valves are available, with both
single and multiple ports opening.
The screw knob valve (MMD6) can connect up to six individual drain lines. The
MMD12 can connect to 12 individual drain lines. Each connection is individual. The
control knob is located on the operator’s panel. Turning the knob counterclockwise
OPENS the drain valve.
Suction Valves
Hale has valves that mount in the suction of the midship pump.
The Hale Master Intake Valve (MIV) becomes an integral part of the fire pump. When
the valve is ordered as part of a Hale Midship fire pump, the pump will pass UL
requirements up to 1,500 GPM (5,678 LPM) from the draft through a single 6” NST
suction hose with the valve in place. When two valves are mounted to the fire pump,
the pump can achieve NFPA Performance Point flows of 2,000 GPM (7,580 LPM)
from draft with dual 6” NST suction hoses. NFPA Performance Point flows of
2,250 GPM (8,516 LPM) is achieved with two MIVs and three 6” NST suction hoses.
The Hale MIV meets NFPA requirements for operations using a large diameter supply
hose. (See Figure 3-13: “Master Intake Valve (MIV),” on page 47.) Further information
on the MIV can be found in manual P/N 029-0020-35-0.
