• Prior to installation, flush line to remove debris.
• Install valve horizontally “in line” (cover facing UP), so flow arrow matches flow through the line. Avoid
installing valves 6” and larger vertically. Consult factory prior to ordering if installation is other than
described.
• Install inlet and outlet isolation valves. NOTE: When using butterfly valves, insure disc does not contact
control valve. Damage or improper valve seating may occur.
• Provide adequate clearance for valve servicing and maintenance.
• Install pressure gauges to monitor valve inlet and outlet pressure.
• Provide adequate drain for cover chamber discharge if “wet drain” option is selected. Consult “Valve
Cover Capacity” chart on appropriate main valve Engineering Bulletin.
• Connect Solenoid Pilot to appropriate power source in compliance with local electrical codes.
Proper Automatic Control Valve start-up requires bringing the valve into service in a controlled manner. All
adjustments to control pilots and speed controls should be made slowly, allowing the valve to respond and
the system to stabilize. NOTE: Control Valves should be set‑up in a dynamic (flowing) condition for
proper start‑up. Provisions for flow must be made to insure proper settings.
1. Close upstream and downstream valves to isolate the valve from line pressure. Open all Isolation Ball
Valves, if so equipped. If valve is fitted with adjustable speed controls, turn needle(s) in (clockwise)
until seated, and return out (counterclockwise) 1-1/2 to 2-1/2 turns. These are approximate settings,
and should be fine tuned to suit system requirements.
2. Slowly open upstream isolation valve to allow controlled filling of the valve. Vent entrapped air by
carefully loosening control tubing or pipe plug at the highest point possible. If valve is equipped with
a Position Indicator, open Air Bleed Petcock to vent air. Water will be milky in appearance and will
begin to clear as air is vented. Re-tighten when water vents clearly.
3. Slowly open downstream isolation valve.
4. Energize and de-energize Solenoid to insure proper valve actuation. NOTE: Solenoid is equipped
with a Manual Operator. Engaging Manual Operator simulates electricity to the Solenoid. Turning
Manual Operator clockwise engages Solenoid. Turning Manual Operator counterclockwise
disengages Solenoid.
5. Fine tune Speed Controls (if equipped) to suit system requirements. Adjust Closing Speed Control
clockwise for slower closure and counterclockwise for faster closure. Adjust Opening Speed Control
clockwise for slower opening and counterclockwise for faster opening.
