150 psi rated retractable injection quills are for water mains where pressures do not exceed 150 psi.
With caution, operators can remove and insert alloy solution tubes made from Hastelloy C, Alloy 20, Titanium, or Stainless Steel for inspection or replacement purposes, while the main remains in service. No shutdown is required. A mechanical assist may be required for alloy solution tubes larger than 1/2".
We do not recommend inserting PVC or CPVC solution tubes into water mains when pressures in the main are above 100 psi. This poses an unnecessary risk to the operator.
These units are available with or without a ball check valve. Some models include an integrated injection check valve.
A single stainless steel hook and chain locks the solution tube securely to the main connection. A stainless steel limit chain will stop the solution tube from extending past the main connection during withdrawal.
Solution tube adapter and packing nut thread together, compressing the 300 series o-ring against the outer diameter of the solution tube.
