General

The Trisuria also provide the stainless steel penstock/slide gate in heavy duty and medium duty application. Stainless steel is design for non-corrosive water treatment facilities, sewage treatment plants, water diversion projects, drainage and many other fluid control installations. Generally, stainless steel penstock is design for medium water head with very litter leakage rate performance. The EPDM resilient rubber seals provide the highest leakage resistance with

long life duty cycle. Although, stainless steel penstock having the low head limitation, Trisuria Heavy duty stainless steel series (SS-H) can double up the head level with higher leakage resistance as well. The structural design and leakage requirement is accordance with  BS 7775:2005 and AWWA C-501:1992.

frame and Gate

The frame and gate is fabricated by either SS304 or SS316. Trisuria provided the standard flat back or spigot frame with round or rectangular opening.

The gate and the seating surface having the good flatness for better performance. Penstocks for special applications can also be custom made.

Seating

All seating faces is seal by EPDM rubber. This is the best solution for lowest leakage requirement. EPDM having the good resistance for chemical reaction and high temperature. Double sided seating surface is for maximum leakage resistance.

Spindle

KT Penstock provided stainless steel RISING stem with the extension optional. Gunmetal nut used for better thrust movement.
