11 Class 1 Valve Manual
p/n: 119138
Evaluate the best location for the valve installation, taking the following into consideration:
• Customer requirements
• Discharge location on the vehicle
• Maintenance accessibility
• Linkage Geometry – Refer to Hale Products service bulletin SB92 for details.
• Valve actuation
o
Manual – left or right close; actuator position: left, right, top, or bottom; push rod or
handwheel
o
Electric – wiring path; securing wire harness and mounting the controls
o
Clearance around the actuator
• Control panel layout
5.1 Principals of Operation
• The Class 1 ball valve controls flow with a stainless steel internal ball. The valve uses a quarter-
turn design to minimize travel and is operated by manual lever, remote push rod, electric actuator,
or gear-driven actuator.
• The “swing out for service” design allows for watertight operation that is easy to use and easy to
maintain.
5.2 Installation Guidelines
• Pump body and compartment – Examine the pump body and the available space inside the pump
compartment to decide the best pump discharge opening to use. Account for space restrictions
from piping and valve control linkages throughout the compartment.
• Fasteners – Verify that all fasteners used on Class 1 valves are plated Grade 8 steel. Apply Loctite
#242 or equivalent to any threaded fasteners used to install an inlet or outlet valve adapter. Install
and tighten fasteners in a cross pattern, to ensure an even, watertight seal between the valve and
adapter. Torque the fasteners to a maximum 45 ft-lbs (Grade 8). [Refer to Hale Products
document ES018-002 – Torque Values for Threaded Fasteners, for more details.]
• NPT fittings – Use a joint sealing compound (Loctite or equivalent) on all NPT threaded adapter
fittings.
• Victaulic® connection – If the valve outlet adapter uses a Victaulic® fitting, connect the appropriate
coupling seal with a Victaulic® approved lubricant. Follow the recommended Victaulic® installation
procedures.
