Seamless Integration into Your Infrastructure
AVM penstocks and slide gates can be wall-mounted, channel-mounted, or embedded into the structure depending on your design requirements. The frame, invert, and guide system must align precisely with concrete tolerances and site access conditions.
Distinguishing Between the Two Water Heads
A seating head forces the gate against its seat, while an unseating head acts in the opposite direction. Consequently, allowable water heads are not interchangeable and must be specified for each side of the structure.
Select the hydraulic function
Sluice gates, stop logs, and wall flap valves are grouped together here as they share the same integration approach within hydraulic structures, while serving distinct operational functions.

| Selection Point | Documented Information |
|---|---|
| Sluice Gate or Channel Penstock | Movable gate designed to isolate an opening or channel. Features three- or four-sided sealing depending on the mounting configuration. |
| Back-pressure regulating valve | Gate lowered to allow water overflow and regulate level—distinct in function from a standard isolation valve. |
| Stop logs | Removable components designed to temporarily isolate systems or structures, specifically during maintenance operations. |
| Wall-Mounted Flap Gate | A passive discharge device designed to open under upstream head and prevent backflow. Not intended as a substitute for an actuated valve. |
| Materials | Available in 304L, 316L, or duplex stainless steel to suit your application requirements. Features HDPE guides and EPDM seals in documented configurations. |
| Valve Lines | Light-duty series: 200 × 200 to 1,200 × 1,200 mm. Heavy-duty series: 500 × 500 to 3,000 × 3,000 mm; custom dimensions engineered upon request. |
| Design Standards | AWWA C561 and BS7775 referenced for AVM penstocks. Specific requirements, testing procedures, and allowable leakage rates to be defined per supply contract. |
A slide gate is sized based on the opening dimensions, water head, and operating loads. An in-line valve pressure rating is no substitute for this engineering verification.

This depends on the design as well as the seating or unseating head pressures. Water heads on both sides must be provided to validate sealing performance and structural resistance.
Designed for temporary positive isolation or separation, typically during maintenance operations. Safe installation, removal, and load conditions during handling must be properly planned.
