ƒ Storage: All equipment and materials after inspection shall be carefully prepared for storage or immediate installation.
ƒ Handling: All equipment and materials shall be handled in accordance with manufacturer’s recommendations.
ƒ Description: The emergency cylinder valve closure system(s) is to be specifically designed to close 1-ton containers and 150-pound cylinders. This shall be accomplished by using an electrically operated motor directly coupled to the cylinder or container valve. The electrically operated actuator shall utilize common 120 VAC as a power source for the actuator control system. The system shall use an assembly that is clamped directly to the cylinder or container valve and shall not require any external supports. The system shall also avoid contact with the yoke and yoke adapter system. The system shall be designed to allow an operator to open the valve without removing the actuator by depressing an open button on the actuator. The system shall be designed to simultaneously close up to two cylinder valves when activated using the standard control package. Systems that cannot close multiple valves simultaneously shall not be acceptable.
ƒ The emergency cylinder valve closure system(s) shall consist of the following components:
ƒ Electrically operated actuator capable of producing no more than 40-ft. lb. of stall torque. Motor power supply is obtained from 120 VAC circuit. The control system coverts to the required DC voltage.
ƒ Two piece bracket system: One piece permanently attached to the electric actuator. Second half is field attached to cylinder valve prior to installation of vacuum regulator or a closed yoke adapter. The Electrical actuator bracket shall be installed into lower bracket and secured using a pin. Bracket assembly shall use a hitch pin to allow quick disassembly and shall not rely for support on packing nut or yoke assembly for support, or any other external support. The fully assembled actuator and bracket shall weigh less than 9 pounds.
ƒ No part of the bracket mounting system shall attach to the yoke. Equipment attaching to the cylinder yoke shall not be acceptable.
ƒ A corrosion resistant multi-connector electrical cord of 20 feet in length shall be used to supply power to actuator. The cord shall be pre-wired to the control panel by the manufacturer. The contractor shall be responsible for installing the quick connect plug to each electric actuator.
ƒ Control Panel
ƒ The control system shall be designed to activate two electric actuators simultaneously. The valve closure system shall be furnished with a local control panel with a FRP NEMA 4X enclosure to house the required controls. The control panel shall be mounted in the chlorine room. The control panel shall include the following switches and pilot lights: Emergency Stop, Reset Switch, System Ready, and System Activated.
ƒ The control panel shall be labeled by Underwriters Laboratory to UL 508A.
ƒ All control devices shall be mounted on the front of the control panel enclosure. Each control device shall have an engraved or etched nameplate describing its function.
ƒ The control panel shall have a nameplate identifying it. The nameplate shall be plastic with engraved letters and shall be securely fastened to the control panel.
ƒ The control panel shall have a terminal strip for connection of power and control circuits in the field. All terminals shall be numbered, and terminal numbers shall be shown on the manufacturers wiring diagram.
ƒ Electrical connections of supply power, external alarm and control wiring shall be the owner’s responsibility.
ƒ Uninterruptable power supply shall be mounted and wired external of the control panel by the contractor. The
UPS shall have a minimum 1500 VA output power with no transfer time required. The UPS shall utilize “true” on-line double conversion technology. The UPS shall be installed in a motor control room or equipment with a
NEMA 1 Environmental rating.
ƒ Uninterruptible power supply shall provide supply power when main power is offline or lost. The system shall be configured to either activate or not activate the actuators when supply power is lost. This shall be field selectable by removing a jumper. The UPS shall be able to provide up to 4 hours of emergency power.
Fabrication & Manufacturing, Inc.

ƒ The system owner shall provide 120 VAC, 15 A power supply for the system. The supply power shall be field wired to the control system as required. Contractor to install in accordance with the N.E.C., State and local code requirements.
ƒ The contractor shall inspect all equipment immediately upon delivery to site. All visible damage shall be reported and repaired.
ƒ Damaged equipment shall not be installed until repairs have been made in accordance with manufacturer’s written instructions and approved by the Engineer. Damaged items shall be sent to factory for repair or replacement, unless otherwise approved by the Engineer.
ƒ Install equipment in complete conformance with manufacturer’s written instructions and Engineer approved shop drawings.
ƒ Notify the Engineer of any discrepancies.
ƒ Make all field connections required to place equipment in proper operation in accordance with manufacturer’s instructions and recommendations.
ƒ Provide all required appurtenances for a complete installation.
ƒ If required by the specifications, the equipment manufacturer shall provide a qualified factory trained technician for equipment startup and operator training.
ƒ The manufacturer will provide one person on site for a maximum of two days.
