Penstock is available in several sizes depending on the customers´s needs.
The Penstock is made of stainless steel and after working it is fully pickled to ensure optimum durability.
The Penstock is of a robust and simple construction ensuring limited maintenance and low running costs.
The Penstock principle
The gate is operated by means of af handle or a gear motor. By manual as well as automatic activation of the spindle, the gate plate will be lifted or lowered.
The location of the gate plate with respect to the seal is controlled by four PEHD guide rails.
These four guide rails helf minimize the seal pressure and thus prolong the life of the seal.
The seal has been specially designed for use in a Penstock. Its unique design makes the gate tight in both directions of flow.
The seal is made of EPDM rubber featuring great resistance to the aggressive substances that may be present in waste water.
Penstock type 05.1/05.2 is suited for most shut-off jobs, however, a scissors gate model 05.5 should be used when 100% tightness is required.
The Penstocks are dimensioned for a water pressure of 5mVS as standard.
Model 05.1 is for installation in channels, model 05.2 is for wall installation.
Operated method for Penstocks:
– Hand wheel
– Gear motor
– Pneumatic or hydraulic cylinder
Operation and support bearing is mounted on a console. Console for Model 05.1 is as standard, mounted directly on the frame. Model 05.2 has a various options of mounting positions, depending on the distance from hole to position of operation:
– Console mounted directly on the frame (short distance)
– Console mounted on a separate frame (long distance)
– Wall bracket
– Straight column (through floor/ceiling)
By large dimensions the Penstock can be equipped with a Spiral Bevel gearbox and two spindle arrangements.
As standard the Penstock is made in AISI 304, and fully pickled after production to ensure optimum durability. If an even better corrosion resistance is required, we can supply Penstocks made of acid-proof steel AISI 316 or SMO steel.
