725HF High Flow Piston Valves

The 725HF Series high flow piston valve fills small bottles, foil packs, and other packaging with absolute accuracy at up to 450 ml per second.

Ideal for adhesives, cosmetics, creams, grease, lubricants, inks, and sealants, the 725HF is also used for potting electronics and applying braze pastes.

Using a slight pull-back at the end of each dispense cycle ensures accurate fill amounts. A unique ultra-high molecular weight (UHMW) polyethylene diaphragm replaces traditional seals, providing complete separation of the fluid from the cylinder body without the need for seal maintenance.

Features

  • FDA-compliant wetted parts
  • Fully adjustable flow rates
