TECOFI knife gate valve is constituted by\u00a0a gate which slides in a narrow body. The\u00a0upper part of the gate, in closed or opened\u00a0position, stands out from the body.
\nThe gate is sharp thanks to a chamfer of\u00a0extremity. The polishing of faces facilitates\u00a0the penetration of the gate in the\u00a0product. At the end of valve closing, the\u00a0gate is stuck to the joint to assure the\u00a0seat tightness.<\/p>\n

The gland packing guarantees\u00a0the internal tightness of the\u00a0valve.
\n\u2013 This technology of TECOFI knife gate\u00a0valve is particularly adapted for difficult\u00a0using conditions such as thick or pow \u2013\u00a0dery products.
\n\u2013 Traditional gate valves contain important\u00a0retention zones. Also thick or powdery\u00a0products prevent the good functioning\u00a0of the wedge. The TECOFI knife gate\u00a0valves with the upper gate part always\u00a0out of body can always open and being\u00a0sharp always can close with sharp edge.<\/p>\n
APPLICATION
\n\u2013 Pulp production.
\n\u2013 Water, water treatment, waste water.
\n\u2013 Chemical industry: powdery or crystallizing\u00a0products.
\n\u2013 Brewery industry: wine-producing.
\n\u2013 Pulverized products: cement work, pneu -matic transport, stocking.<\/p>\n
\u0004 GENERAL CHARACTERISTICS
\n\u2013 Function ON\/OFF or regulation.
\n\u2013 Wafer threaded mounting.
\n\u2013 Unidirectional tightness, direction indication thanks to the arrow on\u00a0the body.
\n\u2013 Small retention zone: the gate is guided in the body and has little\u00a0clearance.
\n\u2013 Gland assembly: packing and O-ring (same materials as seat joint) to\u00a0assure the elasticity and decrease the operating torque.
\n\u2013 Small head loss.
\n\u2013 Possibility to regulate thick fluids with the adaptation of a diaphragm\u00a0ring.<\/p>\n
