cross-section drawn of ZMBX pneumatic film tee cut-off valve

             the drawing of pneumatic stop valve

instruction

ZMQ type pneumatic film cut-off valve adopts top oriented structure, with many spring actuators.

Cut-off valve from receiving instnanent adjustments signals, cutting, open or change the flow direction of medium, reach to pressure, flow, temperature or level parameters automatic control.

Widely used in petroleum, chemical, metallurgical, power, light industry and textile and other industrial sectors of production processes automatic control and remote control system.

 This series of products are film type, piston type two kinds. Body structure has single seat, sleeve, two-seat (tee) three, two sealed forms are packing seal and bellows seal two kinds, product nominal pressure rating has PN10, 16, 40, 64, nominal diameter scope four their ~ 200mm. Suitable fluid temperature by - 60 ~ 450 °C. Flow characteristics for quick opening.

Product features
Cut-off valve adopts multiple spring actuators and adjusting mechanism with three pillars pillar are linked together, the whole height can be reduced by about 30%, weight can reduce about 30%.
According to the body fluid mechanics, design of principle into the non-equal low flow resistance port, the rated flow coefficient increases by 30%.
, trims the sealing parts have strict type and soft seal two kinds, strict type for surfacing welding cemented carbide, soft seal type for soft material production, closing good sealing.
Van with balancing valve internals and improves the cut-off valve of allowable differential pressure.
Van bellows seal type of mobile stem formation completely sealed, plugging away medium leak of possibility.
, piston actuators, operation, use differential pressure great strength.
