 ♦ Overview

The Z673H pneumatic knife gate valve used entire circular the channel design, the knife board bottom end processes the knife edge, the smooth finish is high, has guaranteed the good leak-proof quality. Has in the knife board upper extreme installment hardly poly four ethylene, the scraper, may prevent abrasion matter and so on dust gravel enters the stuffing box. Gathers the rubber fat or contains the wear-resisting cone which the Ni wear-resisting cast iron makes to install in the knife gate valve import end, may prevent the pellet material directly washes out in the seal, thus may improve the working condition, lengthens the life. According to the need, may all around establish many flushings mouth in the valve body, straight takes over the use of the air, the steam or the water carries on the flushing, prevented the settling gradually piles up, is specially effective regarding the input difficult fluid. This valve design compact, occupies the space slightly, the weight light, is easy to install, wear-resisting to guard against stops up the measure to consummate, to be advantageous for the service, the service life is long. Widely satisfies the papermaking, the paper pulp industry, the industrial sewage and the city sewage treatment, the chemical plant, flies ash processing, disperses the shape material transportation, food drink industry operation requirements and under the working condition harsh environmental condition.
