PVA Positive Displacement Dispense Valve With Micrometer, Ss, (0.10-1.45 Cc)

PVA MV500 — Positive Displacement Dispense Valve with Micrometer | Stainless Steel | 0.10–1.45 cc

The PVA MV500 Positive Displacement Dispense Valve with Micrometer delivers highly repeatable, volumetrically controlled fluid dispensing for precision manufacturing applications. The stainless steel wetted path and micrometer-controlled shot size adjustment (0.10–1.45 cc) make this valve ideal for dispensing adhesives, solder paste, epoxy, conformal coatings, and other medium-to-high viscosity fluids in electronics assembly, medical device manufacturing, and industrial production environments. Positive displacement technology ensures consistent shot volumes independent of fluid viscosity variation or inlet pressure fluctuations.

Frequently Asked Questions

What is a positive displacement dispense valve and how does it differ from other valve types?

A positive displacement valve moves a fixed, mechanically controlled volume of fluid per cycle, independent of fluid viscosity or supply pressure. This contrasts with time-pressure valves, which rely on pressure and time to estimate shot volume and are more susceptible to variation. Positive displacement valves like the PVA MV500 are preferred for applications requiring high repeatability and tight shot-to-shot volume control.

What fluids is the PVA MV500 compatible with?

The stainless steel wetted path makes the MV500 compatible with a wide range of fluids including solvent-based and water-based adhesives, epoxies, solder paste, conformal coatings, greases, and other medium-to-high viscosity materials. Confirm compatibility with highly aggressive or reactive chemistries with PVA or MTE Solutions before use.

How is shot volume adjusted on the MV500?

Shot volume is adjusted using the integrated micrometer, providing precise, repeatable control over the displacement volume from 0.10 cc to 1.45 cc per cycle. The micrometer allows fine adjustment without tools for quick changeover between deposit sizes.

Is the PVA MV500 compatible with automated dispensing systems?

Yes — PVA dispense valves are designed for integration with PVA automated dispensing platforms and robotic dispensing systems. Contact MTE Solutions to discuss integration requirements for your specific dispensing system or production line configuration.

What is the typical maintenance requirement for the MV500?

Regular flushing with compatible solvent after use and periodic disassembly for cleaning of the stainless steel wetted components is recommended. The frequency depends on the fluid dispensed and production volume. Consult PVA’s maintenance documentation for detailed service intervals and procedures.
