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.
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.
Needle Valves open and close by the axial movement of the disc that is connected to a crank and shaft mechanism which the gearbox commands.
When the valve is in fully open position, due to its aerodynamic design, it causes very low head loss and maximum flow capacity.
The disc is guided by circular disc guides deposit welded to the main body, which causes minimum friction loss and stable movement.
Stem, rotated by the gearbox, commands the crank mechanism which moves the disc axially to change the opening area of the valve.
When the valve is in fully closed position, due to special sealing mechanism, drip tight sealing is achieved.
Due to pressure-independent disc operation and special gearbox, torque values needed even in large sizes are minimum.
Quick Pressure Relief Valves protect pumps and water distribution systems from extreme situations by relieving the excessive pressure immediately.
It opens fully in case of a sudden pressure peak and closes drip tight when the pressure level does not exceed the pre-set pressure level.
Main focus is in 316L body units which are normally on 2 weeks manufacturing lead. Due to prompt delivery these find major acceptance on site repair works / marine / shut-down works etc.
Axi-Flex /Stepped Couplings will connect similar or dissimilar pipes, same of differing OD and the wrap-a-round Repair Couplings find favour with end-user like DEWA, ADWEA, EMICOOL, EMPOWER etc. in situation where they experience pipeline cracks and associated leakages.
Sizes from DN50 to DN4000 but as the size goes up the pressure capability decreases.
