We are offering Pinch Valve. Pinch valve is a modified version of laboratory pinchcock. a rubber sleeve is protected under a cast iron casting. the fluid passing through does not come in contact with either body covering or any other metal parts of the valve except the sleeve. hence the body and other metal parts are almost permanently not subjected to the corrosive action of the fluid. the flow through the valve is straight and full as that of a pipeline, when the valve is fully open. further, the collar of the sleeve eliminates gasket. the valve is simple hand wheel operated of rising wheel type. therefore the operation of the valve is just simple as other wheel operated valve. the in-between stoppage will allow the desired throttling. thus the valve offers positive control over flowing media.

We are offering Knife Edge Gate Valve. Sludge, slurries, powders, problems fluids that challenge today?s pulp and paper, chemical, textile, sewage, plants and sugar mills. we meets this challenge, by refining the knife gate valve. a precision-buffed knife plate cuts even the heaviest sludge, sharply and without erosion. one-piece trim provides corrosion-resistant, hi performance shut-off over a long service life. compact, lightweight knife gate valves have been handling industry's problem fluids dependably for many years. technical spec. : body : astm a351 gr cf8/cf8m/cf3m/cn7m/astm a216 gr wcb/is 210-fg 260. gate : astm a479 ty304/316/304l/a-20. stem & piston rod : astm a479 ty304/316/304l/a. gate adaptor : astm a479 ty304/316/304l/a. gland / gland packing : sg iron, is 210-fg 260 / ptfe impregnated asbestos/apt. yoke & yoke sleeve : carbon steel / phosphor bronze. engineering operations : hacatnuda tworheel, gear operated, hydraulic, pneumatic / electrical actuator operated, chain wheel operated, lever operated.
