| The pneumatic membrane cuts off the valve Characteristic |
. Have the bright card The pneumatic membrane cuts off the valve Adopt 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 valve Valve 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 valve Cut off the valve Xu 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. |
