Purge and Fill Valves
Any hydronic system may be drained, flushed, and refilled at the same time using these plumbing valves. They have an adjustable packing gland, PTFE seats, and PTFE seals, and are activated by a blowout-proof stem. Valves are appropriate for use in residential, commercial, and industrial applications and enable for the isolation and draining of an expansion tank in a closed-loop hydronic heating system.
