The WLD1703S is used on air and gas applications as drip traps on system mains and other piping runs. These drain traps are ideal for outdoor applications where units are subject to freezing.
• Rugged, stainless steel body and hardened seat
• Handles a wide range of pressures up to 250 PSIG
• Works in any position (horizontal preferable)
• Integral strainer with blowdown option
• Three-holed balanced discharge
• Freeze-proof in vertical flow-down position
The disc type liquid drain trap has a cyclic on/off operation with a disc that is pushed open when condensate is present and pulled closed when air or gas tries to escape.
Selection / Sizing / Capacities
| Notes: |
1) Maximum back pressure not to exceed 80% of inlet pres sure. |
|
2) To determine gallons per minute of flow, divide values in chart by 500. Example: 600 lbs/hr = 600 –: 500 = 1.2 GPM |
Blowdown valve allows strainer to be cleaned without removal.
Installation and Maintenance Drain Trap can be installed in any position; however, horizontal is preferred. Installation should include isolation valves for maintenance purposes.
Dirt is the most common cause of premature failure. The strainer may require periodic cleaning. For full maintenance details see Installation and Maintenance Manual.
Drain Trap shall be a Disc Type with an all stainless steel construction. Body shall have a built-in strainer with optional blowdown valve. Integral seat design and disc to be hardened for long service life. Unit shall be capable of installation in any orientation and self-draining when mounted vertically with flow direction downwards.
