HOLMBURYDIN SERIES

Our DIN couplings are offered with a choice of either ball or poppet valve mechanisms for automatic flow shut-off when disconnected. The ball valve option is primarily intended forapplications where compatibility with existing equipment is essential. For new applications we recommend poppet valve couplings as the more durable option.
