Coplastix® Series 50 - 40

Rectangular faced penstock.

The Coplastix® Series 50-40 is a rectangular faced penstock designed and manufactured to suit modern industrial and domestic effluent environments

  • Latest synthetic materials for both sealing mechanisms and door construction combined with the use of steel or stainless steel in the construction of the penstock frames ranges.
  • A range of penstocks suitable for use in most water, sewage and effluent treatment plants.
  • The penstocks are available for wall mounting and can be provided with either
    • manual or
    • power operators,
  • Manufactured in sizes ranging from 400mm square to 2000mm square as standardWEIR (Downward Opening)

 

Coplastix® Weir Penstocks are constructed as described for the wall mounted type other than the stem is secured to the lower edge of the penstock door via a cast iron bracket, thus permitting maximum unhibited flow over the upper weir edge of the door. Flush invert does not apply for Weir Penstocks. The sealing arrangements for the Coplastix® Penstocks combine the use of resilient and low friction synthetic materials which ensures a high degree of sealing with easy movement.

Technical Specification

Materials Of Construction
ComponentDescription
FramesFrames are manufactured from mild steel to BS EN 10025: 1993 grade S275 or stainless steel to BS EN 10088:1995 grades 1.4301 (304) or 1.4401 (316). Mild steel frames can be protected to suit sea water, potable or sewage application, stainless steel - natural finish. The penstock frames for both wall and channel mounting (downward closing) have a resilient flush invert seal to allow smooth transmission of the flow through the penstock.
Frame SealsThe sealing arrangements for the Coplastix® Penstocks combine the use of resilient and low friction synthetic materials, which ensures a high degree of sealing with easy movement.
DoorsDoors are manufactured as a composite sandwich construction comprising a lightweight rigid, cellular core with a fully welded steel box section matrix between two other skins of rigid, compressed composite plastic which is asbestos free, ultra violet stabilised, rigid and non toxic. All materials are chemically bonded and sealed. Doors for non-rising spindle penstocks have a stainless steel lining tube inside the central vertical box section of the inner matrix.
SpindlesRising or non-rising type in stainless steel BS EN 10088:1995 grades 1.4301 (304) or 1.4401 (316) with extension spindles in the same material as standard.
Frame YokesFrame yokes form an integral part of the frame and are positioned to allow removal of the door should this be necessary. The yoke material is the same as for the frame.
Stem NutsThe stem nuts are phosphor bronze to BS 12167:1998. For non rising stems, the nut is housed in a cast-iron bracket secured to top of the penstock door. For rising stems, the nut is housed in the handwheel.
Fixing BoltsCan be supplied when requested
Pressure PadsAdjustable pressure pads are fitted as standard and pre-set at the works to provide maximum degree of water tightness.
