Lancer Valve Plunger Spring for Check Valves - 03-2021

Lancer Valve Plunger Spring for Check Valves - 03-2021

The Lancer Spring for Check Valve is the essential tensioning component for the internal fluid-stop mechanism. This high-tensile stainless steel spring provides the physical force required to hold the check valve plunger against its seat, preventing the back-migration of carbonated water into the syrup lines.

Problem Solved: Prevents 'flavor-migration' and system pressure loss. Replaces springs that have lost their tension due to chemical fatigue, which allow fluids to bypass the check valve and contaminate the supply lines.

Symptoms of Failure: Finding 'watery' syrup in the lines, the BIB pump cycling on its own when the unit is idle, or finding bubbles in the syrup-in lines near the manifold.

Technician’s Note: Never reuse a spring that shows any signs of rust or compression set. A weak spring is the most common cause of high-pressure carbonated water backing up into a low-pressure syrup pump, which can destroy the pump's internal diaphragm.
Technical Specifications:
  • Material: 302 Stainless Steel (Acid Resistant)
  • Application: Internal Check Valve Tension
  • Manufacturer: Lancer
  • Compatibility: Standard Lancer Check Valve Assemblies
