Valvepac
One of the most common leak problems encountered by maintenance
engineers, is leaks from valve gland stuffing boxes.
Traditional methods of valve sealing such as thermo-setting
compounds, substitute packing or sealants can lead to a fresh
batch of problems that include:
Difficulty in operating the valve.
Gland leakage re-occurrence when operating the valve.
Removal of sealant during onsite shutdown maintenance proving
time consuming and costly.
Smaller valves are almost impossible to re-pack and scrapped
incurring costs for removal, the replacement unit and its
installation.
Stork Cooperheat's solution to these difficulties is the Valvepac
system. Valvepac allows the leaking valves to be re-packed with
the original manufacturer's gland packing by direct injection into
the gland stuffing box. The valve remains fully operational and
can be re-packed in the same way at any time in the future.
 The
Valvepac system can be used on any type of valve that incorporates
conventional gland/packing. Gland leaks with temperatures from
sub-zero and over 600 ēC and pressures ranging from vacuum to
3500psi can be re-packed using this system. Whilst gland leaks of
steam and water are the most common, gland leaks of chemicals,
hydrocarbons, acids and almost any product can be re-packed
on-line using the Valvepac system.
