PTFE Double-Ball Construction
The TDBL designation identifies a PTFE double-ball check-valve arrangement. This differs from the ceramic double-ball construction specified for K4VTC1 and K4VTC3.
PVC Head and PTFE Seals
The PVC/PTFE combination is an important part of the original wet-end specification. Check the actual chemical and operating conditions before confirming material suitability.
Why Use a KOPkit?
PULSAtron KOPkits package common liquid-end service components for scheduled maintenance. A typical kit includes the pump head, diaphragm, valve assemblies and associated hardware, depending on the model.
VTT1 Versus PTT1
K4VTT1 has a PVC head, whereas K4PTT1 has an FPP head. Both list PTFE double-ball valves and 3/8-inch OD tubing, but their head materials are different.
Connection Details
The specified tubing connection is 1/4-inch inside diameter by 3/8-inch outside diameter. Confirm the original fittings and wet-end designation before installation.
Maintenance Procedure
Isolate electrical power and the chemical feed system. Relieve pressure and follow the official Pulsafeeder instructions for liquid-end component replacement.
