Mounting Types : Wall Mounted with Flat Back Types or Spigot Types.
○The Flat Back type provides ease of mounting againts wall or structures, ensuring secure installation and optimal flow control without additional fittings.
○The Spigot type are one end of the pipe is expanded (spigot end), while the other end is fitted to the spigot end of the adjacent pipe (SOCKET). The joint is typically sealed using a gasket or packing to prevent leaks, ensuring the integrity of the water flow under pressure.
Aperture Sizes : Square | Round | Rectangular
Durable construction : Single piece casting structural to minimum 5 times of safety factor against structural failure. High solid epoxy finish is applied to prevent corrosion to the structural. Penstock for special application can also be custom made.
Seating & Wedges : All seating faces are use with bronze or gunmetal and having it’s good surface contact to achieve water tightening. Seating face gaping allowable is less than 0.1mm. The side wedges, top and bottom wedges are taper machined to give maximum contact face and wedge action. Top and bottom wedges devices are required for all OFF seating penstock. All wedges are design for easy adjustment to achieve better water tightened.
Spindle : Rising and non-rising stem based on customer requirement. Gunmetal thrust nut are used for better thrust movement. Extension stem is given in various lengths as for various site elevations.
Spindle Nut : Manufactured from gunmetal material for Rising and Non-Rising stem applications.
Clamping Bar : Manufactured from cast iron material. Attach adjustable side wedges as pressure bar along the side of the frame as pressure adjuster toward water pressure and leakages control.
Stem Guide : Main for guiding the stem. It is casted in cast iron. Stem guide spacing shall not exceed l/r ratio of 200.
MUFF COUPLE : Casted by stainless steel and used as join for extension stem between penstock and headstock.
HEADSTOCK WALL BRACKET : Casted by cast iron. It is mounted direct to the floor slab for headstock side wall mounting. Used together with headstock as operating pedestal to penstock in manual or motorize operation.
Easy Maintenance : The penstock is designed with accessibility in mind, allowing for easy maintenance and servicing. Components are replaceable and the gate can be manuallly or mechanically operated.
Versatile Applications : Suitable for water treatmentplants, flood control systems, irrigation systems, and industrial applications where controlled flow and shut-off are required.

Type of Penstock's Mounted Method:



You may come across two types of mounting styles: Flush Bottom and Normal Mount.


Flush Bottom:
Flush bottom penstock design is used whenever a continuous smooth opening is desirable. Typical installations include waste water setting tanks, aeration tanks, sedimentation and flocculation basins. The advantage of this penstock is to prevent the rubbish stay or block at the slot between the bottom of the penstock and the mounted wall. This is used for preventing the gate operation stuck and water leakage cause by the stuck at the bottom gapping. This penstock is providing a flat plane across the bottom of frame while the gate is open by using EPDM seal. The seal is mounted to the frame with stronger support by corrosion resistant fasteners. The EPDM seal is design for easy replaceable without dismantle the frame. Bottom wedges will not used on the flush bottom closure.


Normal Mount:
A normal mount is a more conventional mounting style, where the penstock is mounted above or offset from the bottom of the structure. The flange or the mounting bracket is often raised slightly from the penstock might run vertically, at an angle, or where there is space between the base and the pipe.

Type of Penstock's Operation:

On Seating Pressure :

•Pressure forcing the door onto the frame.

Off Seating Pressure : Pressure forcing the door away from the frame
On/Off Seating Pressure : Pressure action from both sides

Applications

○Sewage Treatment
○Water Treatment
○Food control
○Industrial Drainage
○Hydro Dam
