Available on back-order
Description
Key Features
-
Terminal discharge valves situated at the end of the pipeline and are installed in a compact stilling sump
-
Stilling sump providing submerged discharge with safe and quiet energy dissipation
- Hydraulic balance, no differential loads, low operating effort, small actuator
- Resilient seal for drop-tight shut off
- Submerged discharge, safe, quiet energy dissipation and cavitation free
- Chloride resistant stainless steel internal parts, bronze ported body with epoxy coated ductile iron components for high corrosion resistance
-
Shaped multi-ports giving wide control range, can be customized for specified condition
-
External mechanism allowing easy maintenance and visible indication
-
Fine screw thread for slow speed operation and fine adjustment, good positioning and gradual flow change
AVK’s Supa Maxi™ range of universal tensile couplings sets a new standard. The patented SupaGrip™ sealing support system with flexible bracket ensures full support of the gasket and full tensile strength on all pipe types up to PN 10. Supa Maxi™ couplings are very easy to mount with the possibility of ±4° angular deflection, the permanent protection caps, the lifting eye and the fact that they are tightened from the sleeve side with no need for re-tightening the bolts.
