VALVE OPERATION MANUAL
• Never use pressurized gases with plastic piping systems.
• Ensure all testing is done using established and secure hydrostatic equipment.
Certain liquids may be prone to vaporization [o-gassing] which might cause presure uctuation.
Valves may be damaged.
• Do not apply excessive weight or mass on top of the valve.
• Avoid slurries, this might result in uneven ow.
• Avoid crystallized or gelled substrate, this might result in uneven ow.
• Always operate valves and piping systems within their designed engineering limits and reccomended conditions.
• Ensure adequate space is always kept around the valve for inspections and maintainence.
• Ensure the right materials, seats and valve types are used that have adequate chemical resistance to the substrate.
• Keep valves from being exposed to direct sunlight for long periods. UV rays might aect the composition.
• Ensure routine and periodic maintenance and inspection is done to avoid costly problems.
SECTION 1 - GENERAL OPERATING GUIDELINES
• When suspending valves use common sense, ensure adequate support and spacing is maintained.
• Thermoplastic may be damged with impacts and sharp objects. Avoid blunt and sharp trauma.
• Ensure cartons and packages are stored appropriately, excessive cartons being stacked might collapse.
• Avoid contact with paint, tar-sand, insecticides and pesticides, and highly corrosive agents.
• During assembly and handling do not carry valves by their handles.
• Keep valves from being exposed to direct sunlight for long periods. UV rays might aect the composition.
• Prior to assembly ensure a quick and eective visual check is done to ensure items are not defective.
SECTION 2 - TRANSPORTATION AND STORAGE
• Perform a visual check prior to installation.
• Wear adequate protective equipment when working with tools, solvents, power drills etc.
• If using U Clamps or anything similar during assembly make sure not to over-tighten.
• During installation of piping systems ensure adequate spacing and hoops are designed in the system.
• Ensure no unnecessary stresses are caused on the piping system such as tension, compression, impact etc.
• Visually check to determine the direction of ow of valves before installing.
• Before hydrostatic testing ensure that union nuts are rmly screwed into position. Take care not to over-tighten.
• If connecting to metallic systems ensure that no undue stress is caused to valves.
• Never use a pipe wrench on thermoplastic.
• For detailed solvent welding, threading and anging connections read Hydroseal Canada’s Technical Guide.
SECTION 3 - INSTALLATION
• Do not exert excessive force when opening or closing valves.
• If sand or other large particles are in the piping system ensure to ush these out before operation of valves.
• Ensure that valves are opened and closed only by trained people, never use tools to open/close valves.
• If valve provided is lubricant free ensure that water is owing before attempting to operate handles.
