PENSTOCK

Penstock are intended to manipulate the flow of water to the plants, waterways, channels, irrigation systems and the like.

You should always keep in mind that slide gates have some leakage.
According to DIN 19569 is allowed leakage

q= (0, 02 – 0, 05)*L [liters/sec], where L (m) is length of sealing.

This leakage can be minimized if the construction work (walls of the structure) carried out very accurately.

Depending on the physical properties of water such as aggressiveness and pressure, penstock are made of:
• Stainless steel (AISI 304 or similar)
• Carbon steel, corrosion protected
• Plastic material
• Aluminum.

Material of seal is EPDM, VITON, NBR, silicone, PTFE or PA.

EPDM material for seal is resistant to aged, ozone, oil, climate conditions, hot water, diluents, washing liquid.
Temperature range -40° to +80° C.

Possible mounting positions

• Channel, built-in channel and sealed on three sides,
• Built on the wall and sealed on all four sides,
• Overflow, channel mounted on the wall and sealed on three sides.

Possible ways of manipulation

• Manually wheel and helical spindle,
• Manually, reducer and helical spindle,
• Electric motor, actuator-reducer and helical spindle open / closed
• Electric motor, actuator-reducer and helical spindle position regulated and pending of parameter.

The optional relationship between the movement of the helical spindle and nuts, could be:
• Nut rotates, the spindle has a helical axial movement,
• Helical spindle rotates, the nut has an axial movement,

The direction of sealing
• Upstream
• Downstream
• Both sides.

It is desirable to always select such a combination of movements that the spindle and nut are above the water level.
