Bronze Gate Valves
•
Gate valves provide complete shut off,
providing the seats remain undamaged,
and offer very little resistance to flow in
the open position. Gate valves are best
suited to infrequent valve operation,
as any dirt in the system can cause
scuffing of the seats. Gate valves are
not recommended for use in the partially
open position because vibration and
erosion of the disc may occur.
•
Service temperature and pressure
indicated on the identification plate or
body marking should not be exceeded.
•
Hattersley gate valves have not been
designed as fire safe valves.
•
Valves must be installed into a well
designed system and it is recommended
that the system be inspected in
accordance with the appropriate
member state legislation.
