Component Specifications

Definition
Valves for diaphragm pumps are precision components that regulate the directional flow of fluids by opening and closing in synchronization with the diaphragm's reciprocating motion. They ensure one-way flow, prevent backflow, and maintain system pressure in various industrial applications. These valves are critical for the pump's efficiency, handling abrasive, viscous, or corrosive fluids with minimal leakage.
Working Principle
Valves operate on a check valve principle, using pressure differentials created by the diaphragm's movement. During the suction stroke, inlet valves open to allow fluid into the pump chamber while outlet valves close. During the discharge stroke, inlet valves close, and outlet valves open to expel fluid. This cyclic action ensures controlled, pulsation-dampened flow.
Materials
Common materials include stainless steel (e.g., SS316 for corrosion resistance), PTFE (for chemical inertness), EPDM or Viton rubber (for elasticity and durability), and ceramic (for abrasion resistance). Material selection depends on fluid compatibility, temperature, and pressure requirements.

  • Pressure Rating Up to 150 psi (10.3 bar)
  • Temperature Range -20°C to 120°C
Standards
ISO 2852, DIN 11851
