Swing-Check and Spring-Check
Non Return Valves are ideal for preventing back flow of water when pumps are
switched off.
The plastic swing-check valves
offer low flow resistance while the spring checks are more positive in
shutting. They are available in 1½ and 2” sizes in plain and double union
styles, the later allowing the valve to be dismantled and cleaned.
The brass non-return valves
offer higher flow resistance but more positive shut off.
They are stocked in 4 sizes
from 1” to 2” female threaded BSP.
