Check valves

Overview

Medray procures check valves for maintenance, replacement and project requirements. Provide the model or reference, quantity and operating conditions so the required configuration can be matched and sourced across available suppliers. Check valves respond to the pressure difference across the valve to permit forward flow and close against reversal. Swing, spring-assisted and dual-plate wafer designs have different opening and closing behavior. Selection should account for minimum operating flow, cracking pressure, installation orientation and pump transients. Matching the valve to system dynamics helps avoid unstable operation and abrupt closure. Technical details to confirm: Flow range and permissible pressure loss; Cracking pressure and closing behavior; Installation orientation; Pump cycling and reversal conditions.
