Sanitary Check Valves
Sanitary check valves allow flow in one direction and close automatically when flow reverses. Caspian Edge supplies spring, ball and other hygienic non-return configurations for pumps, transfer systems and process utilities.

Product Overview
Check valves protect process lines and equipment from reverse flow without external actuation. Selection depends on valve style, cracking pressure, installation orientation, cleanability, line size and whether the media contains particles or has higher viscosity.
Product Range
Final availability and technical details are confirmed against size, connection, operating conditions, quantity and project documentation requirements.

Controlled closure and defined opening pressure for common hygienic duties.

Serviceable gravity-assisted non-return configuration for hygienic transfer and compatible process lines.

Compact clamp-connected non-return assembly for space-conscious hygienic piping and equipment packages.
Configuration & Options
Valve selection is more reliable when body material, connection, seal, actuation, finish and documentation are reviewed as one package.
