WLD1900 Series Float Type Liquid Drain Trap
 |
HOW IT WORKS
This liquid drainer has a float-operated valve that gives the trap a modulating flow characteristic. The amount of liquid flowing into the drainer is sensed by the float which positions the main valve to discharge the liquid at the same rate as it is received.
FEATURES
• In-line repairable
• All stainless steel internals
• Hardened valve seat for longer service life
• Cast Iron body
