ProMinent Multifunction Valve Pump Accessory for Metering Pumps, PVDF Body, Back and Relief Pressure, 740427

ProMinent 740427 multifunction valve pump accessory is designed to enhance the performance and reliability of dosing pump installations. Tailored for use with ProMinent Beta, Gamma/X, and Delta metering pump ranges, this accessory integrates essential functions for process safety and precise chemical dosing.

Constructed with a robust PVDF body and a PTFE coated diaphragm, the valve offers resistance to a wide variety of chemicals. The use of high-grade FKM and EPDM seals ensures compatibility with aggressive media and enduring leak-tightness under continuous operations. Two rotary dials allow easy adjustment and reset of operational settings.

A key feature of this unit is its dual function as both a back pressure and relief valve. The back pressure valve opens at 1.5 bar, maintaining consistent line pressure for accuracy even at varying flow rates. The relief valve opens at 6 or 10 bar (dependent on the specific pump model), providing system safety by preventing overpressure situations. The integrated priming aid simplifies startup procedures, and a service-friendly discharge line enables straightforward maintenance, minimizing downtime.

Provides uniform back pressure for metering accuracy and process stability. Prevents dosing inaccuracies caused by fluctuating line pressures. Relief valve function protects pumps and system plumbing from overpressure damage.

Resistant to aggressive chemicals, suitable for chemical and water treatment applications. Compatible with ProMinent's full range of solenoid metering pumps, including alpha and gamma/X models. Meets the demanding requirements of industrial, laboratory, food & beverage, water treatment, and pharmaceutical sectors.

Simple installation and maintenance procedures via rotary dial adjustments and service line.

Engineered to meet the rigorous standards of modern process engineering, this multifunction valve ensures stable dosing operation and offers operational safety. The part is delivered as a ready-to-install accessory with all necessary fittings for integration onto supported pump heads.

Applications include water treatment dosing, chemical manufacturing processes, laboratory fluid handling, and food industry chemical metering. This accessory upholds the reliability and engineering precision expected from ProMinent.
