PULSAtron L1900600-FPP Five-Function Valve Adjustment Knob

The Pulsafeeder PULSAtron L1900600-FPP is a replacement adjustment knob designed for compatible five-function and five-function/degas valve assemblies used with chemical metering pump systems. This component provides the manual adjustment interface for the designated valve mechanism.

Pulsafeeder parts documentation identifies L1900600-FPP as an adjustment knob for five-function valves. The five-function/degas valve parts schedule further describes it as a black FPP adjustment knob.

Replacing a damaged or missing adjustment knob with the correct original equipment component helps maintain the intended manual control arrangement of the valve assembly.

Five-Function Valve Adjustment Knob

The L1900600-FPP adjustment knob is part of the manual adjustment mechanism in compatible Pulsafeeder five-function valve assemblies.

Five-function valves are used with chemical metering pumps to provide multiple fluid-control functions within a single valve assembly. Depending on the valve design and configuration, these functions include pressure relief, back pressure, anti-siphon protection, bleed and drain operations.

The adjustment knob provides the operator interface for the designated adjustment mechanism. The exact adjustment procedure depends on the valve model and should follow the manufacturer instructions.

Five-Function Valve Applications

Pulsafeeder identifies L1900600-FPP in the parts diagrams for its five-function valve equipment.

Potential applications include:

• PULSAtron chemical metering pump accessories
• Pulsafeeder five-function valve assemblies
• Compatible five-function/degas valve assemblies
• Chemical dosing system valve maintenance
• Water treatment chemical feed equipment
• Industrial chemical injection systems
• Replacement of damaged valve adjustment knobs

Five-Function Valve Operation

Compatible five-function valve assemblies combine several functions used in chemical metering installations.

These may include pressure relief, back-pressure regulation, anti-siphon protection, bleed and drain functionality.

The PULSAtron L1900600-FPP is an adjustment component within the valve assembly. It is not a complete five-function valve, pressure relief valve or chemical metering pump.

Replacement and Maintenance

Inspect the adjustment knob during routine valve maintenance for cracks, deformation, damage and difficulty operating the adjustment mechanism.

A damaged knob should be replaced with the correct manufacturer-specified component. Inspect the associated adjustment mechanism for wear or damage before installing the replacement.

Do not force a seized adjustment mechanism or substitute an incompatible knob.

Compatibility and Installation

Before purchasing the Pulsafeeder L1900600-FPP, verify the original part number, valve assembly model and applicable parts diagram.

The standard five-function valve parts diagram lists two adjustment knobs per assembly, while the five-function/degas valve parts diagram lists one. Confirm the quantity required for the specific assembly.

Follow Pulsafeeder maintenance procedures and isolate and depressurize the chemical feed system before servicing the valve.
