Mazzei (MV-5-PP) 1/2" Metering Valve Customized "V Port" Characterized Seat Control
Mazzei MV-5-PP 1/2" Metering Valve with Customized V Port Characterized Seat
Engineered for precise chemical injection control in water treatment systems, the MV-5-PP metering valve delivers consistent, repeatable flow regulation through its characterized V-port seat design.
Characterized Flow Control for Chemical Injection Systems
V-Port Seat Design
The customized V-port geometry provides characterized flow control, meaning you get predictable, linear adjustments throughout the valve's range. No guesswork when dialing in chemical dosing rates.
Polypropylene Body
Chemical-resistant PP construction handles chlorine, acids, peroxide, and most water treatment chemicals without degradation. Built for continuous exposure in harsh injection environments.
Precision Metering
Fine-thread adjustment stem allows micro-adjustments to flow rates, essential when pairing with Mazzei injectors for accurate chemical dosing in irrigation, sanitation, or industrial water treatment.
Repeatable Control
Once you set your flow rate, the characterized seat maintains that setting session after session. No drift, no recalibration—critical for automated chemical feed systems.
Designed for Mazzei Injector Systems
The MV-5-PP metering valve integrates directly with Mazzei 1/2" chemical and air injectors, including the 287, 287V, 487, 584, and 684 series. Use it to throttle chemical flow upstream or downstream of the injector, or to control suction side flow rates for precise dosing control. Standard 1/2" NPT female threads fit most water treatment plumbing systems.
Chemical Feed Accuracy
Dial in exact dosing rates for chlorine, fertilizer, acid, or any injected chemical with repeatable precision.
No Special Tools
Hand-adjust the valve stem without wrenches or special equipment. Thread-on connections install quickly.
Long Service Life
Polypropylene wetted parts resist corrosion and chemical attack for years of trouble-free operation.
System Integration
Pairs perfectly with Mazzei venturi injectors for complete control over chemical injection rates in any flow condition.
