wall mounted penstock
Wall-Mounted Penstock is the most common and widely used of penstock in both water and waste water works application in Malaysia and around the world. Lecotech Wall-Mounted Penstock is fabricated with Stainless Steel in BS 7775 / AWWA C561 specification standard. The penstock can be equipped with rising or non-rising stem option and can be used for on seating and off seating water pressure direction. Lecotech offers the sizes from 150mm x 150mm until 1200mm x 1200mm for Wall-Mounted Penstock.
This type is also have a unique self-adjusting seal design that can achieve minimal equal seating and unseating (bidirectional) leakage rates, for sizes of 1300mm x 1300mm up to 4000mm x 4000mm are also available in bidirectional configurations. The maximum leakage rate is lower than the maximum allowed recommended by BS 7775 Standard under normal conditions.

Wall Mounted Non-Rising Stem Penstock
As a standard, non-rising stem gate configurations are used with self-contained frame designs. Therefore, the stem extension does not support the axial load (only torque) and less wall brackets are required. As a general rule, a stem guide should be installed every 3 meters of unsupported stem extension.
Wall Mounted Rising Stem Penstock
As a standard, rising stem gate configuration are used with open-frame designs. Therefore, the stem extension has to support the axial load when the gate is operated to avoid any buckling failure. As a general rule, a stem guide should be installed every 2 meters of unsupported stem extension.
