Class 1 Valve Manual
1. Introduction & Specifications
The new Class 1 four-piece stainless steel ball valves were created for reliability, corrosion resistance,
customization, and ease of maintenance.
Class 1 Stainless Steel Ball Valve
• The Class 1 stainless steel ball valves are available in 2.0”, 2.5”, and 3.0” sizes.
• Ball valves are composed of four main components: valve body assembly, inlet and discharge flange
adapters, and actuator.
• The center bodies are constructed of 304 stainless steel, and the balls are machined from 304
stainless steel.
• The stainless steel ball valves are bi-directional.
• The stainless steel ball valves use a single-piece seat and seal.
• A wide variety of 304 stainless steel valve end flanges are available to meet most of your plumbing
connection needs.
• Removing three of the four bolts on both flanges allows the valve to swing away from the plumbing,
and provide access to the waterway.
• For each valve size, the same stem geometry is used for all actuation options, eliminating the need
to change or remove the stem. For many options, only one bolt is required to add or remove a
valve handle.
• All valves are designed to meet or exceed NFPA 1901 standards.

Electric actuators require Class 1 controller 117010 to operate.
The 117010 smart switch uses position feedback from the actuator to display
the valve’s open/close position. The smart switch can also be field programmed
for both high- and low-flow preset valve positions.

4. Safety Information
!
!
The Class 1 ball valves are designed for optimum safety of its
operators. For added protection, please follow the safety guidelines
listed in this section and adhere to all warning, danger, caution, and
important notes found within this manual.
The following section must be carefully read, understood, and
followed by all installers and operators before attempting to install or
operate Class 1 Valves. Failure to follow the installation and
maintenance requirements discussed below may result in serious
personal injury and/or damage to equipment.
When developing departmental apparatus operating procedures,
incorporate the warnings and cautions as written herein.
• READ ALL INSTRUCTIONS THOROUGHLY BEFORE BEGINNING ANY
INSTALLATION OR SERVICE PROCESS.
• Use care when removing the Class 1 valve from its packaging to prevent personal injury
and/or damage to the unit.
o The weight of the Class 1 ball valves varies according to size. Check your bill of
lading for the approximate weight. Where deemed necessary, be certain to use
proper lifting support devices or additional personnel.
• Before beginning any inspection, installation, maintenance, or service of any kind on the
valves, verify that the pressure has been released from the system. Lock out the equipment
in the system in accordance with the manufacturer’s recommendations.
• Installation should be performed by a trained and qualified installer. Be sure the installer has
sufficient knowledge, experience, and proper tools before attempting any installation.
o The installer is responsible for observing all instructions and safety precautions in his
or her daily routine as dictated by regional safety ordinances or departmental
procedures.
• DO NOT tamper with or disconnect safety features which could affect safe operation of
the valve and/or cause personal injury.
• Do not weld in proximity to the valve. Heat transfer from the welding process will damage
the plastic valve seals.
• No modifications or additions may be made to the Class 1 valve without prior written
permission from:

• Disconnect all power sources before servicing an electric valve.
o Electrical systems have the potential to cause sparks during service or repair.
Eliminate explosive or hazardous materials in the environment during installation or
service.
