Polski (EUR)725DA-SS ADJUSTABLE PISTON VALVE WITH SS FLUID CHAMBER
Product code: 7021014
Piston valves for precise deposits of viscous fluids
The 725D Series dispensing valves apply repeatable amounts of medium-to-thick fluids, including greases and silicones.
• 725DA-SS Model: Adjustable stroke for fluid flow and snuff-back control.
• 725D-SS Model: Non-adjustable version providing a constant stroke for fixed setups.
• Robust piston design for long service life.
• Durable stainless steel wetted parts.
• Ideal for consistent dispensing of high-viscosity materials. More
