PULSAtron J40117 Foot Valve & Strainer Assembly
PULSAtron J40117 foot valve and strainer with FPP body, CSPE/Hypalon seat, ceramic check ball and weight for 3/8-inch ID x 1/2-inch OD tubing.
The PULSAtron J40117 is a foot valve and strainer assembly designed for compatible PULSAtron chemical metering pump suction lines. Installed at the chemical source, it combines a check valve with a strainer to support reliable chemical pickup while helping prevent unwanted debris from entering the suction tubing.
The J40117 uses an FPP filled-polypropylene body, CSPE/Hypalon valve seat, ceramic check ball and ceramic weight. It is configured for 3/8-inch ID x 1/2-inch OD tubing.

Foot Valve & Strainer Function
The J40117 installs at the end of the pump suction tubing inside the chemical supply tank or container. Its integrated check-valve action helps maintain liquid in the suction line when the metering pump stops.
This can help the pump retain prime between operating cycles and reduce the amount of air that must be removed from the suction line when the pump restarts.
Integrated Suction Strainer
The strainer surrounds the chemical inlet and helps prevent larger debris or foreign material from entering the suction tubing. Keeping contaminants out of the suction line can help protect the pump head and valve components from blockage or improper seating.
The strainer should be inspected periodically, particularly when chemicals may contain sediment or when contamination is present in the supply tank.
FPP, Hypalon & Ceramic Construction
The J40117 combines an FPP filled-polypropylene body with a CSPE/Hypalon valve seat and ceramic check ball. This material combination is identified in PULSAtron documentation as FPP/CSPE/C.
Chemical compatibility should always be verified for the actual process fluid, concentration and operating conditions before installation.
Ceramic Check Ball
The ceramic ball operates against the valve seat to provide check-valve action. During the pump suction stroke, the pressure change allows chemical to enter the suction tubing. When conditions reverse, the ball seats to help restrict chemical from draining back toward the supply tank.
Ceramic Weight for Stable Positioning
The assembly includes a ceramic weight that helps keep the suction tubing extended downward and positions the foot valve near the bottom of the chemical container.
The foot valve should remain properly oriented rather than lying horizontally on the bottom of the tank. Correct positioning allows the check ball to move and seat as intended.
Tubing Connection
The J40117 is designed for 3/8-inch ID x 1/2-inch OD tubing. Some catalogs simplify this connection to 1/2-inch OD tubing; both descriptions refer to the same documented J40117 tubing configuration.
PHC3 Wet-End Application
Current PULSAtron replacement-parts documentation identifies J40117 for PHC3 wet-end pumps. It may also appear in additional compatible pump configurations that use the same FPP/CSPE/ceramic suction-side arrangement.
The complete pump model and existing wet-end configuration should be checked before selecting a replacement foot valve.
Benefits of the J40117 Assembly
- Combines foot valve and suction strainer functions
- Helps maintain pump prime when the pump stops
- Helps restrict chemical drain-back through the suction line
- Strainer helps keep larger debris out of the pump
- Ceramic weight helps position the suction line in the chemical tank
- FPP body with CSPE/Hypalon valve seat
- Ceramic check ball for compatible chemical applications
Maintenance & Selection
Inspect the J40117 if the pump becomes difficult to prime, loses prime after shutdown or shows reduced chemical output. Check the strainer for blockage and inspect the check ball and valve seat for deposits, wear or chemical deterioration.
Before replacement, confirm that the application requires the J40117 FPP/CSPE/ceramic configuration with 3/8-inch ID x 1/2-inch OD tubing.
