For water, waste water, chilled water & many other services, to permit pipelines “flex” a bit. Metallic pipes expand and contract when the ambient (or service) temperatures vary and non-metallic pipes (which may be buried) will move with ground settlement etc. Where probable movement can be envisaged the values are designed by a compensator which can flex, thus avoiding undue pipeline damage. Interesting applications are reservoir inlet/outlet connections, pump connections, differing flange standards either end, axial or angular offset of new to old pipelines. Sizes from DN50 to DN5000 and pressures of PN6 to PN25 on rubber, but the larger sizes would be lower pressure capability.. Higher pressures and temperatures in 316SS.
Critically acclaimed for raw sewage lines, for shut off service. Eccentricity of the plug (and its turning away from the flow path) is a great feature in allowing (sewerage) solids to pass freely. Sizes and Pressures. Sizes 3” (DN80) to 48” (DN1200) and Pressures of PN10, PN16. Smaller sizes up to DN300 can also be rated PN25
Pump Control Valves protect pumps, pipelines, and other system components by isolating the pipeline from the sudden velocity changes associated with pump starting and stopping.
The “Active Check Valve” logic of operation, is the method of pumping system control that prevents surges rather than eliminating them.
Solenoid Control Valves are simple electrically activated on/off valves that can be of critical importance in controlling flow in every water system.
The electrical signal used to activate the solenoid can be sent from timers, relays, clocks, pressure, level or flow transmitters, etc.
