Pulsafeeder L380DT01-PVD PVDF Five-Function Valve - 100 PSI, 3/8-Inch OD
PVDF five-function valve for compatible PULSAtron and CHEM-TECH metering pumps. Features pressure relief, back-pressure control, anti-siphon protection, air bleed and discharge drain. Rated configuration: 100 PSI; 3/8-inch OD tubing; PTFE O-rings.
Five Essential Functions in One Pulsafeeder Valve
The Pulsafeeder L380DT01-PVD combines five chemical metering system functions in a single PVDF valve assembly. Designed for compatible PULSAtron and CHEM-TECH pumps, it provides a convenient way to manage discharge pressure, priming and maintenance without installing separate accessories for every function.
What Does the Five-Function Valve Do?
- Pressure Relief: Provides a relief path when excessive discharge pressure develops.
- Back-Pressure Control: Helps maintain consistent metering output, including applications discharging to atmospheric pressure.
- Anti-Siphon Protection: Helps prevent unintended chemical movement through the pump.
- Air Bleed: Allows trapped air to be released during priming.
- Discharge Drain: Provides a controlled method for relieving discharge-line pressure during service.

Why Choose PVDF Construction?
PVDF is used in chemical-handling equipment where resistance to selected aggressive fluids is important. The valve combines a PVDF body with PTFE sealing components. Always confirm material compatibility for the chemical concentration and operating temperature.
Applications and Pump Compatibility
The five-function valve is listed for compatible PULSAtron metering pumps up to 240 GPD and selected CHEM-TECH Series 100 and Series 200 models. Confirm the exact pump, tubing arrangement and operating pressure before installation.
Operating and Safety Considerations
The 100 PSI value identifies the valve pressure-rating configuration. The manufacturer manual notes that pressure relief may occur above the nominal rating; do not treat the designation as a precise relief-opening setpoint. Follow the official installation and operation manual, including return-line routing and safe depressurization procedures.
Replacement and Ordering
Order L380DT01-PVD when the application requires the 100 PSI PVDF five-function valve with 3/8-inch OD tubing and PTFE O-rings. The L380DT03-PVD version uses 1/2-inch OD tubing.
