The pneumatic membrane cuts off the valveCharacteristic

. Have the bright cardThe pneumatic membrane cuts off the valveAdopt the executive body of many springs and regulate the organization and is linked to three posts, the whole height can reduce about 30% , weight can be lightenned by about 30%.
.The pneumatic membrane cuts off the valveValve body design according to hydromechanical principle section low to is it is it flow line to hinder to flow, specified flow coefficient increase 30%.
. An sealed part has tight type and seal two kinds softly in the valve, tight type, in order to pile and weld the hard alloy, the soft sealed type is made for the soft material, seal of good performancly while closing .
. One, has improved in the balancing type valveCut off the valveXu use press difference.
. Corrugated pipe sealed type transform sealing complete into to valve stem that move , stop up possibility that the medium leaks definitely.
. Piston type executive body, operate strength big , use the difference of pressing to be great.

1)This index of properties of product carries out GB/T4213-92;
2)Allow to pigeonhole difference and is greater than the nominal pressure and fetch nominal pressure value of the form, smaller than and equal to nominal pressure value not changing ;
3)The allowing value can mix and improve and allow to press difference with different air cylinders in order to use standard air cylinder value in the form.
