For appropriate installation, check pertinent pressure/temperature diagram,
as shown on our main technical data sheets.
Security notes
• If overpressure or overheating are possible, the piping system must be
provided with adequate protection systems
• Befo re assembling, check on the valve th e marked pressure limit (it refers
to a temperature of 20°C)
• Immediately prior to valve installation, the pipework to which the valve
is to be fastened should be checked for cleanliness and freedom from
debris.
• Do not operate any maintenance with piping system under pressure
• Do not overstress the assembled valve with additional weight
• Do not hit or strike the valve
• Open/close slowly to avoid hammer shock
• Do not overheat the valve
• The operator should use suitable hand protection at extreme temperature
conditions.
• The valve should only be used in the open or closed position. Regulating
or throttling service should be avoided.
• After installation, the valve may be opened and closed fully to confirm
satisfactory operation.

Installation
• Confirm that the pipe threading length is correct to avoid excessive
penetration of the pipe into the valve, which would otherwise cause
damage.
• Ensure the threads are properly engaged and proceed to tighten the
valve onto the pipe. The wrench must only be located on the valve end
into which the pipe is being threaded to avoid distortion of the valve.
• After installation, the valve may be opened and closed fully to confirm
satisfactory operation.
