Tecofi » Knife Valves » Handwheel Non Rising - DN 50 to DN 900

Handwheel Knife Valves are generally used for infrequent operation, spending most of their lives fully open or fully closed. 

The workhorse Handwheel Knife Gate Valves have a non rising spindle handwheel actuator.
A threaded spindle is mounted off centre, fixed to the handwheel and runs in a threaded nut mounted to the gate.
Turn the handwheel anti-clockwise, the spindle turns and screws the nut up the stem pulling the gate up and opening the valve.
Turn the handwheel clockwise and the nut and gate are forced back down, closing the valve.
Neither the handwheel nor the spindle moves up & down.
These are used where space is at a premium.

Our VG Handwheel Knife Valves are produced with a stainless steel spindle, solid cast iron handwheel, bronze bush and a thick plated steel support plate.  A solid design for years of trouble free operation.
(Unusually this range is also available with Rising Actuator too.)

Our air operated Knife Gate range is available ATEX Certified for explosive atmospheres. For more information please visit our ATEX page: ATEX
