VALVE CARTRIDGE, VALVE CARTRIDGE KIT, VALVE INCORPORATING A VALVE CARTRIDGE OR VALVE CARTRIDGE KIT AND A METHOD OF ASSEMBLING A VALVE

A valve cartridge (1) having a body (10), a piston (12) and a piston support (22). The body has a seat (14). The piston (12) is supported on the piston support (22) and movable between first and second positions. The piston (12) is spaced from the valve seat (14) at the first position and the piston...

Beschreibung
Zusammenfassung:A valve cartridge (1) having a body (10), a piston (12) and a piston support (22). The body has a seat (14). The piston (12) is supported on the piston support (22) and movable between first and second positions. The piston (12) is spaced from the valve seat (14) at the first position and the piston (12) seats on the valve seat (14) at the second position. The piston (12) and piston support (22) form a confined space. The volume of the confined space is at a maximum when the piston (12) is at the first position and is at a minimum when the piston (12) is at the second position. The piston (12) is under bias such that the piston (12) is biased away from the valve seat (14) to the first position and, in use, the piston (12) is able to seat on the valve seat (14) in the second position when subjected to sufficient pressure to counter the bias.
