Manufacturing Program Dual Plate Check Valves Model C and B Dual Plate Check Valves Duplex for Desalination Dual Plate Check Valves Model EMG Dual Plate Check Valves Hydraulic data Ball Check Valves BV-05-38 Swing check valve B6 50 Check valves and strainers

Dual Plate Check Valves Operation The plates of the check valve open when for example the pump is started and immediately close again when the pump is switched off. This closure is only driven by the hydrostatic pressure and the reset force of the spring. The check valve can be installed vertically and horizontally making it a flexible solution for different applications. Model C Features Short face to face distance according to ISO 5752, Series16, and DIN 3202 K3 Valid for installation between flanges PN10, PN16, PN25, PN40 or ANSI-150. Maximun working pressure 40 bar. For higher pressures,...

Ball Check Valves - BV-05-38 Flanged and threaded type Features: Maximum working pressure 16 bar up to DN200,bigger sizes 10 bar. Valid for installation between PN10 or PN16 flanges or BSP thread. Temperature from -10ºC to +80ºC Minimum differential pressure to ensure water tightness 0,5 bar. Full bore. Easy maintenance. Anti-corrosion epoxy coating. Operation: Operation is based on a free ball housed inside the body which is pushed by the pumped flow to the side cavity, allowing the liquid to pass through. When the pump stops and the ball is no longer pushed aside, it takes up a position in...
